Events Take Place Post Chapter 210
—————————————————————————————————————

The American Troops made their move as they threw in a flashbang. Megumi watched as Yuji knocked away the flashbang. He covered his ears with Cursed Energy and held his face with his hands, shielding himself from the light and sound.

Bang!

The Flashbang sounded as Megumi opened his eyes to see a gigantic curse burst through the building.

Megumi gritted his teeth in annoyance, thinking, 'It's Cursed Energy! It's a Special Grade! Hold on... what the hell? Why does it feel like my Cursed Energy is being sapped?'

Yuji looked at Megumi and shouted, "Fushiguro. It must have some kind of Cursed Energy Absorption Cursed Technique. Get Clear. I'll handle this one."

Hana looked to Megumi and shouted, "I'll deal with the Cursed Spirits!"

She could not bear to see the non-sorcerers being slaughtered by Curses, so she resolved to exorcise the incoming Curses.

Megumi then felt something chilling coming from outside as he thought in dread, 'What the hell is going on? Who the hell is that?'

Megumi looked to Yuji and Hana and shouted, "Something is coming from outside. Keep things under control here."

Megumi ran outside as he felt the overwhelming Cursed Energy flowing over him. He looked and saw him. A man in a haori, with white hair and blue eyes. For a second, he mistook him.

"Is that... Gojo-Sensei?"

The man jumped down and smiled, asking, "Oh? You know one of my descendants? Is that it?"

The man smiled confidently as he looked at Megumi, thinking, 'He said Gojo-Sensei? A Teacher? Times really have changed.'

"Kogane. Who the hell is this guy?"

Kogane displayed the information.

Culling Games Player: Gojo Ren | 89 Points | 0 Rules Added

Megumi's eyes widened as he realised the severity of the situation.

'He's from the Gojo Clan? Descendants? He's a Reincarnated Sorcerer!'

Ren sighed and asked, "Where can I find Sukuna?"

Ren tapped his foot impatiently, waiting for Mergumi's answer.

Megumi looked annoyed, thinking, 'Another Gojo. Just great.'

Megumi made a serious expression and said, "Sukuna isn't available right now, and we don't plan on him being available. But Kenjaku's different. You can fight him..."

Ren made an irritated expression, asking, "Are you dumb or just desperate? I want to fight the strongest. Ryomen Sukuna. I never got the chance back then. I was born too late."

Megumi's expression darkened at the realisation. This was a man born in the Golden Age of Jujutsu. The Era of Heian.

Megumi took a breath as he sweated, thinking, 'This guy is Gojo-Sensei's ancestor and from the Heian Era. Though his eyes don't look the same as Gojo-Sensei's. No Six Eyes? Then, using the Limitless Technique probably won't be possible. He's got to be strong in some other way, though. His Cursed Energy alone... he has more than Yuta-Senpai. It's way too creepy.'

Ren suddenly disappeared. Megumi reflexively reinforced his body with Cursed Energy, and then Ren reappeared next to Megumi, whose eyes shifted, trying to see him, when he felt a painful sensation in his stomach. It was like the point of impact was drawing everything into itself.

"Aggh!"

'What the?!!'

Before he could react, he was knocked backwards as he was sent flying through a wall.

'That wasn't like in Shibuya with that guy.'

Megumi remembered how Toji would disappear from sight via sheer speed thinking, 'This guy just teleported! Is that his Cursed Technique?'

He slowly got up as he finally felt the pain from that one attack.

"Ugh..."

He lifted his shirt, checking his stomach and seeing that a bit of his skin had been torn off at the point of impact. He grimaced at the realisation, thinking, 'His Cursed Energy draws everything in. You can't be serious.'

Ren laughed, saying, "Hey! Not bad. You blocked it. That's impressive. Most people end up having a hole in their stomach when I punch them, but you were able to block it. You've got good instincts."

'He's a freakish monster to be able to hit that hard. He'd give Itadori a run for his money.'

Megumi made the hand sign as he summoned, "Divine Dog: Totality!"

Ren made a surprised expression.

"Oh? Ten Shadows Technique? This might actually end up being fun. Let's have a good fight. What do you say, Zenin?"

Megumi responded with, "I'm not a Zenin. I never was. I'm living under my mother's name. It's Fushiguro. It's always been Fushiguro. It'll always be Fushiguro."

Ren sighed, saying, "Your father would be sad to hear that."

Megumi scoffed and replied, "He can cry his heart out all he wants. I don't give a shit."

Ren shook his head disapprovingly.

"You're the same as my son. Michizane. He took his mother's name and made his old man sad without any remorse."

Megumi froze for a second, thinking, 'Suguwara Michizane? As in the Suguwara Michizane? This guy... is Okkotsu-Senpai's ancestor too?'

Megumi sweated as he sent out Divine Dog: Totality to attack, only for it to practically freeze in place before it could touch Ren, as Ren sighed, saying, "It's rude to attack someone before the conversation is over."

Megumi stared at the scene of Divine Dog: Totality being unable to approach. A cruel reality made itself apparent to Megumi. His opponent was using the Limitless Technique.

'He's... using Infinity? But... he doesn't have the Six Eyes.'

Ren smiled and said, "Wondering how I can use the Limitless Technique? You see, my Cursed Energy has an innate ability to manipulate space to a certain extent. Not enough to be useful without the Limitless Technique, but... good enough to assist in controlling the Limitless Technique. I also have a lot of Cursed Energy, as I'm sure you can tell. I don't need the Six Eyes."

Megumi stared in disbelief, thinking, 'What in the world did I do to deserve this?'

Ren smiled and asked, "Is there something you're scared of? I guess my descendant must be a Limitless User too, with how you're shaking. You must be close to my descendant since he's your Sensei. Let's become close friends as well, okay? Hehe."

Ren rushed towards Megumi, who made a hand sign, summoning, "Rabbit Escape!"

The rabbits poured out as Megumi used them for cover. He maneuvered around the attack as he landed a slash with Divine Dog: Totality, and Ren backed off slightly, thinking, 'That was a really good hit.'

Ren raised his eyebrows with a smirk as he assessed, "You're stronger than you look. It hurts pretty bad. You'd give some people I know a run for their money."

Megumi looked at the slashing wound, thinking, 'At least I managed to hurt him.'

Ren's wound began healing as it closed up without issue.

'Reverse Cursed Technique, which puts Red and even Hollow Purple on the table for what he could possibly do. This is the worst. I might actually die here. And right before I could get Tsumiki out of here.'

Megumi clicked his tongue as he looked over Ren.

'The Limitless Technique. Even with that much Cursed Energy and his Cursed Energy Trait, it should still be a very taxing technique. Using it for an entire fight shouldn't be possible. That's probably why I was able to land that attack.'

Ren smiled casually, yawning as he patted the dust off his haori.

"My Limitless technique is limited to use for attacks that I can perceive with one of my five senses. Without that input, I can't use it. A Binding Vow in exchange for the reduction of Cursed Energy Output and Control required for use."

Megumi made an annoyed expression, thinking, 'Revealing a Binding Vow doesn't increase the potency of the vow or the user's Cursed Technique. Unless... is that part of the Binding Vow?'

That was when Ren appeared in front of him.

'Not this again!'

Divine Dog: Totality got in the way as they both got sent flying through multiple buildings as Megumi spat out blood. Megumi's vision began to become blurry as he thought, 'It hurts so much... This guy isn't as strong as Gojo Sensei. Was Gojo-Sensei holding back that much when training me?'

Megumi's arms shook as he looked down, trying to see Divine Dog: Totality, but saw nothing but a bloodstain.

'He can... kill my Shikigami in a single hit. You can't be serious. I... can't use them openly? If I didn't sacrifice Totality, I'd be dead right now.'

Megumi slowly tried to get up as he began to sweat in fear, thinking, 'How the hell do I beat this guy? Gojo-Sensei is stronger, but... the difference between this guy and me is so great that I might as well be fighting Gojo-Sensei.'

Ren walked into the building as Megumi looked at him darkly, thinking, 'I have to imagine a version of myself that can beat this guy, but... how?'

Megumi focused as Ren looked to him in puzzlement and said, "Wow. You're so durable. I think we can actually become really close friends if you keep this up. Haha."

Megumi stood up slowly, thinking, 'Things aren't looking good. He killed Divine Dog: Totality, and I've only landed a single hit on him. What's worse? He used Reverse Cursed Technique to heal from it, and he hasn't shown his entire arsenal yet.

Ren smiled, pointing at Megumi with a hand sign and saying, "Cursed Technique Amplification: Blue!"

Megumi's eyes widened as he instantly dived into the shadows to avoid the attack, reappearing behind Ren as he slammed his fist into Ren, sending him flying forward, who thought, 'He used the shadow created by the blue to hide, and since it was still connected to me, he was able to invade my shadow and appear behind me.'

Ren stopped his momentum as he turned around and said, "Smart boy."

Megumi sighed and said, "Stop patronising me."

Ren deadpanned and said, "Alright," as he made a hand sign and said, "Technique Reversal: Red!" as Megumi looked shocked, summoning a Cursed Tool Katana from his shadows to block the attack, only for it to shatter and for the red to hit him as he was sent flying back into a wall, as he felt one of his ribs snap causing him to yell in agony.

Megumi looked at the place he was hit. He was bleeding, and it was so painful that it was messing with his ability to think. He sweated, managing to think through the pain.

'He can use Blue and Red. Not good. But things could still get worse.'

He grimaced at the idea of having to deal with Hollow Purple.

Ren looked confused and asked, "Why are you still looking so expectant? Blue and Red are the pinnacle of the Limitless Technique without Domain, right? Oh? Am I mistaken?"

Megumi looked horrified at the idea that he might have just given Ren the information needed to use Hollow Purple.

Ren smirked as he contemplated it, thinking, 'What would be a way to take Red or Blue to the next level... oh? combining them? Is that possible?'

Megumi ran towards him, thinking, 'I have to stop him before he figures it out!' only for Ren to make hand signs.

"Technique Amplification: Blue. Technique Reversal Red."

A Blue and Red Orb appeared in front of Ren as Megumi froze on the spot. There was no way to move to the side to avoid it, even if that would help. He saw a door at the far end of the room as he moved towards it, thinking, 'I'm not going to make it!'

"Phase. Twilight. Eyes Of Prajna. Nine Ropes. Polarised Light. Crow And Shomyo. The Gap Between Within And Without. Imaginary Mass. Hollow Technique: Purple!"

Ren got the two orbs to fuse, as he thought, 'The power output is too high to control without the Six Eyes. I'll have to reduce the output a bit. Still, it'll be on a different level from just a Blue or Red.'

A purple orb appeared as Ren fired it at Megumi, who tried to dive into the shadows, but his body was too injured.

It hit him in the side, just barely missing his vital organs, forming a hole he was bleeding from as he fell back, bleeding out. Megumi felt like screaming in pain, but he focused his mind as he managed to try to consider his next moves.

'Maybe if I use my Domain... no. He might have his own. If he does, it'll be over and then... he'll go after Itadori. It's not like I could kill him while I'm like this, just with my Domain either. I'm so injured that I think I'm dying.'

Megumi's thoughts shifted to Tsumiki.

'Ugh. No. I'm not going to die here. I can't die. She's depending on me. That stupid big sister. There has to be a way.'

Ren looked to Megumi, saying, "You're the same as the 10 Shadows User from my era. Hey, summon that big guy. Mahoraga right? Summon him. He was fun to fight back then."

Megumi looked at his hands, thinking, 'Summon... Mahoraga? No... not again. I don't want to summon him. Itadori wasn't at fault. It was Sukuna and... me. We were at fault. If I had just been stronger. If I had just known how to use the Reversed Curse Technique... then Mahorraga wouldn't have been summoned in Shibuya. Then Itadori wouldn't blame himself for all of that.'

Megumi thought back to a conversation with Shoko.

[Shoko sighed, asking, "You want to learn Reverse Cursed Technique? It goes like hyoi! And hyo! And like that!"

Megumi grew a tick mark out of frustration.

"You can't be serious."

Shoko sighed and said, "It's not easy to learn. It took Gojo being at the brink of death to learn it. Even a guy as talented as him struggled."

Megumi looked shocked, asking, "There's someone who could put Gojo-Sensei on the brink of death?"

Shoko sighed and said, "Toji Zenin. He had to tire out Gojo and use the Inverted Spear of Heaven, but... he was able to put Gojo into a near-death state. It was so bad that Gojo had no choice but to learn it. Either that or die."

Megumi sweated, remembering Toji from Shibuya, and how Tengen had mentioned him as the factor that had changed everything.

Megumi gritted his teeth and asked, "Shoko-san. Please try to teach me. I need to learn it."

Shoko sighed and said, "Alright. I'll try my best to get it through to you."]

Megumi lay there as Ren looked annoyed, asking, "Aw, are you dead already?"

He turned around, walking away when he heard something.

"Technique Reversal: Imbuement: Max Elephant!"

That's when an arrow of water pierced through the air. It barely missed his stomach as Ren coughed up blood before turning around. He saw Megumi clasping his hands together, mimicking Choso and Noritoshi.

Megumi stood up, thinking, 'This is how Noritoshi uses it, right? Piercing blood. Wow. This works? I... I never would have imagined this before!'

Ren looked dumbfounded, asking, "You learned Reverse Cursed Technique?"

"That's right, ya bastard! I was desperate, you know. I felt like I was going to die. I didn't want to give up. I kept pushing Cursed Energy into my wound. I tried everything until one method worked. It's multiplication. It's Cursed Energy over itself. Then I fueled everything towards that method, and here I am. Alive."

Ren looked confused, asking, "How are you using the Shikigami's abilities without summoning them?"

Megumi pointed to himself and said, "Reversal involves facets of an opposite property of your technique. Ten Shadows lets me summon Shikigami, but if I did that, you'd just kill them, so instead of summoning them, I imbued them into myself!"

Ren smirked, thinking, 'On the brink of death, learning Reverse Cursed Technique would trigger that kind of reaction in anyone. It was the same with me when I fought and lost to Kenjaku. But that jubilation doesn't guarantee victory.'

Ren smiled, thinking back to his battle with Kenjaku.

[Kenjaku blocked an attack from Ren, who jumped back.

Kenjaku looked at his arm and simply said, "Heal", as his Cursed Energy began automatically healing him. The Reversal of Cursed Speech is the ability to influence your own body and Cursed Energy. It can enhance the body and cursed energy, making it capable of things that should be impossible. Ignoring all physical conditions, such as exhaustion, injury or physical limits.

Ren smirked, saying, "That's awesome! Teach me how to use it! No one could teach me, but maybe you can."

Kenjaku sighed and said, "It's the multiplication of Cursed Energy over itself. Though it's not as easy as it is a simple concept."

Ren smirked, saying, "Thanks for the info. I'll figure it out soon!" making a hand sign and saying, "Technique Amplification: Blue!"

The Cursed Seals of the Inumaki Clan appeared on Kenjaku's face as he smiled and said, "Miss."

The Blue flew completely off-target and flew into the distance as if it had listened to his command before Kenjaku said, "Infinity Off" as he coughed some blood up in recoil. The blood dripped down his lips as Kenjaku nailed Ren with a combo of attacks and then knocked him to the floor as Ren lay there.

Kenjaku smiled and said, "Blue. Hit him."

The blue that had missed before returned, hitting Ren right in the stomach as he coughed up blood and his eyes rolled back into his head.

Kenjaku shook his head, thinking, 'He was strong but... too overconfident. That seems to be a trait passed down in the Gojo Clan.'

Then he looked surprised as Ren stood up and laughed maliciously as he shouted, "I finally get it! Reverse Cursed Technique!"

Ren charged towards Kenjaku, who sighed, thinking, 'He still hasn't had enough?'

Ren smirked, shouting, 'It's not over yet!"

Kenjaku then calmly made a two-handed hand sign and said, "Domain Expansion: Sovereign Decree From The Heavens!"

Ren looked surprised before making a two-handed hand sign and shouting, "Domain Expansion: Boundless Axiom Of Space!"

The Cursed Seals of the Inumaki Clan formed on Kenjaku's face as the Domain Clash began, thinking, 'Let's see whose Domain is more refined.'

Ren smirked, thinking, 'As long as mine hits first, I can kill him! Cursed Speech won't help him if I can tear him apart with a flick of my wrist.'

A black dome of the clashing barriers formed only for it to collapse a few seconds later, with Ren lying on the ground, his limbs cut off and holes riddling his body, thinking, 'I lost. I lost for the first time in my life. He managed to beat me without a Domain, and then, when I managed to pull myself together, he crushed all my hopes with his Domain. That refinement, too. He's on a different level. Special Grade. Such a joke to label someone like him with that title and tie him to that level.'

Kenjaku sat down there casually as Ren healed himself with the Reverse Cursed Technique. He was almost completely out of Cursed Energy.

Kenjaku smiled and said, "You've got so much Cursed Energy that you were strong."

Ren got up and asked, "You're not going to kill me and use your technique to steal my body?"

Kenjaku smiled and said, "There's no point. However, it would have been nice. If only you were born a little later or earlier."

Ren sighed and said, "You don't need to tell me things I already feel. I was born too late to experience the joys of the Era of Heian."

Kenjaku laughed and asked, "Is it about Sukuna? Do you really think you'd be able to beat him if you lost to me?"

Ren shook his head and said, "Of course not. What I want isn't to be the strongest. I want to fight the strongest because everyone else is too weak."

Kenjaku sighed and said, "I see, so that's how you feel. That loneliness from being so strong. You want to cure it by fighting someone stronger than you."

Ren smirked and said, "Yeah."

Kanjaku smiled and said, "So? You feel less lonely now?"

Ren paused for a second and smiled, saying, "Yes. I do. I finally understand what it means to face someone stronger. I think I finally understand those around me."

Kenjaku smiled and said, "Haha. Only those who have lost can understand those weaker than themselves. That's funny, isn't it? Though in most cases it's impossible not to lose at least once."

Ren smiled and said, "You're right. From here on, I consider you a friend. Is that alright with you?"

Kenjaku laughed at this and said, "You're a funny guy. I'll give you an opportunity to fight Sukuna. In the future. How about it? I'll call for you when it's time."

Ren smirked and shouted, "Bring it on, Kenjaku!"]

Ren smirked and shouted, "Bring it on, Fushiguro!"

Megumi stood up as he made a hand sign.

"Technique Reversal: Imbuement: Rabbit Escape!"

A perfect clone of Megumi separated from him, his body standing next to him.

Ren's eyes went wide as he smiled maniacally, shouting, "Now that's fun! The Ten Shadows User from back then couldn't do that!"

Megumi rushed towards Ren, thinking, 'No more standing back and hoping for something!'

Megumi rushed in at Ren, who looked dumbfounded, thinking, 'He can't be this dumb from being on a high right? Rushing in alone without his clone?'

Ren stood his ground, but then he heard something.

"Technique Reversal: Imbuement: Nue!"

He prepared for the Clone to rush in as well, but then he suddenly felt a shock run up his leg and through his body as he convulsed in pain. Megumi's clone had its foot crackling with electricity as it ran through the water trail left from the water arrow and then up Ren's leg.

Megumi smirked, manically thinking, 'It's a good thing that the clone can use Reversal as well. His senses are probably overloaded at this point. I'm going to end this myself. This is something Itadori and Hana probably can't do. I'll kill him myself!'

Ren, not being able to see or hear anything, but having realised how he had been hit with electricity through the water, smirked, shouting, "You genius! Give me your best shot!"

Megumi lined up his punch, holding his hand, thinking, 'I said I'd surpass you, Itadori. I wasn't joking around. I was serious. I'll surpass you here and now!'

Cursed Energy flowed into Megumi's hand before he slammed his fist into Ren's face as Black Sparks flew, and Megumi's eyes widened, causing him to think, 'Black Flash! I... get it now. Cursed Energy. I understand it better than ever!'

The clone rushed in as the two Megumis lined up, one behind Ren and the other in front of him. As Megumi focused Ren's attention on him, and his clone began pummelling Ren from behind, who grimaced in pain from the strikes of the clone.

Megumi's clone made a stance as he thought, 'Now that I understand it better, I can even do this!'

"Technique Reversal: Partial Imbuement: Rabbit Escape!"

A barrage of punches hit Ren in the back as if Megumi's Clone had multiple arms and fists. Ren coughed up blood before he laughed, shouting, "This is so much fun, Fushiguro! I think you and I might become friends!"

Ren grabbed Megumi's arm before knocking him towards a wall, and then he teleported behind the clone using Blue and sent the clone flying in the same direction.

"Technique Amplification: Blue!"

Ren fired a blue at them as they dodged, but the rubble fell on the spot where Megumi had been standing, hitting both him and his clone. Ren walked over, rummaging through the rubble and pulling Megumi out of it by the arm.

Ren smiled, thinking, "That was fun."

The Shikigami clone popped out, only for Ren to kill it by splitting it in half. He turned to Megumi and asked, "Hey, can you summon Mahoraga now?"

Megumi stood up slowly, thinking, 'No. If I do it'll just get killed and waste my Cursed energy, or worse, it'll actually beat him and kill me, leading to Itadori and Hana having to deal with it. Hana might be able to, but... I won't risk it.'

That's when Megumi healed himself with the Reverse Cursed Technique. Ren looked surprised and responded to this with, "Hey, there's no point in healing when you're just going to summon Mahoraga."

"I'm not summoning him."

That was Megumi's response.

Ren sighed in annoyance when his eyes widened, and he backed off. Megumi stood on his own two feet and smirked, thinking back.

[Tengen looked at Megumi and asked, "You want to learn how to use a Domain Expansion?"

Megumi nodded, saying, "I need to get stronger."

Tengen nodded and said, "Very well. Let me explain it to you."

Holograms of various sorcerers casting their domains appeared as Tengen explained, "A Domain Expansion is the highest expression of a Cursed Technique where the user paints their innate domain unto reality. Even if you have the same Cursed Technique as another person, your Domains will be different, as it embodies your true self. So who are you, Fushiguro Megumi?"

Megumi looked confused, asking, "What?"

"A Domain is based upon your soul. If you can't visualise who you are, then of course you won't be able to visualise the barrier being imposed on reality."

Tengen said this as Megumi said, "What kind of question is that? I'm..."

"Who are you, Fushiguro Megumi? What exists in the deepest part of your being?"

Tengen asked this as Megumi thought back, and Tsumiki came into his mind, and he said, "I'm someone who lives for one single person. Someone who lives to protect her."

Tengen nodded and said, "Then, when the time comes that you need a Proper Domain Expansion to protect her, it'll come to you."]

Megumi made a hand sign as Tsumiki flashed in his mind, and he shouted, "Domain Expansion: Shadow Chimera Garden!"

The barrier formed as Ren looked around, thinking, 'A Domain Expansion? Well then, I'll just use...'

Megumi appeared before him, grinning as he grabbed his hand and saying, "You don't have a one-handed domain sign like Gojo-Sensei, do you?"

Ren looked irritated as he attacked Megumi, who just weaved and dodged his attacks.

As water shot out from his domain from every angle, piercing through Ren's body, who thought, 'No Summoned Shikigami. The Sure Hit Effect extends to Reversal Techniques, so he can fire attacks straight from the shadows, huh?'

Ren blocked a punch from Megumi, being pushed back as he thought, 'Not just that, but this kid is in a frenzied state. He's a rabid beast.'

Ren felt electricity travel up his leg as he shouted in pain, thinking, 'Straight from the ground?! Damn it!'

That's when several clones of Megumi popped out of the shadows and began slamming their fists and legs into Ren, who thought, 'This kid might actually overwhelm me.'

He teleported away from the group and chanted, "Technique Reversal: Red!"

The attack hit the clones, vaporising them and hitting Megumi, who got flung back into the wall as the domain fell, and Ren smirked, saying, "Your domain is really good. Way better than that 10 Shadows User from back in my time, but you didn't have the experience to hold something of that calibre open for a long time, right?"

Ren smirked, making the two-handed hand sign and began chanting, "Domain Expansion: ..."

His head was suddenly electrocuted from behind as he bled from his nose. He had been targeted in the part of the brain that stores Cursed Techniques. Because of this, Ren knew he wouldn't be able to use his Domain Expansion.

A Megumi clone was standing behind him with Nue imbued in his hand as Ren smiled, saying, "I get it now. I assumed your burnout wouldn't allow you to keep your clones summoned. That was my mistake. You tricked me pretty good, Fushiguro. Haha."

Ren lunged at Megumi, who avoided the attack, and all of a sudden... Megumi took a stance, thinking, 'I'll kill you with the one you killed.'

"Technique Reversal: Imbuement: Divine Dogs: Totality!"

With this, Megumi's fingers sharpened into claws, and he pierced through Ren's stomach, ensuring that he wouldn't be able to use Cursed Energy, let alone Reverse Cursed Technique.

Ren fell to the floor, bleeding out as he said, "Wow. That was the most fun I've had since Kenjaku. Haha. Thanks for the fun fight. Can you tell me your full name?"

Megumi took a deep breath and said, "Megumi. Fushiguro Megumi."

Ren laughed slightly, saying, "Your pops gave you a girl's name? Now I get why you hate him. Dickhead."

Megumi looked surprised, asking, "Why are you acting like this all of a sudden?"

Ren then said, "Being as strong as me is lonely, you know. Only people who beat me can be my friends. Congrats. From here on, I consider you a friend. Is that alright with you?"

Megumi looked confused but said, "That's fine by me."

A part of Megumi couldn't deny Ren that final request.

Ren then smiled and said, "I think I get why my descendant chose you as a student. You're someone who might be able to keep up with them."

Megumi sighed and said, "You're not even close to his level. Don't start spouting nonsense, idiot."

Blood flowed from Ren's mouth, and he smiled and said, "Then he'll need you much more than I thought."

Ren said this as the light disappeared from his eyes and he passed on.

Megumi fell onto his backside, breathing out a heavy sigh of relief, saying, "It's over. It's finally over."
