Re:Zero - Subaru's Heroine Summoning System

Summary:

What if Subaru has his own cheat, albeit arriving a little late?

It's the typical golden finger system that lets him summon a bunch of different heroines from other fiction.

Starting with Raiden Ei.

P.S - Yeah, this isn't the best summary, but it would do for now.

Work Text:

A/N: While I was messing around with my phone, suddenly I thought of this random idea.

 

Hey, why not write a fanfic where Subaru gets a system? Not just any system, but something that could summon different girls across all fiction?

 

I made this because I'm so fucking bored and needed an outlet.

 

Do not expect anything from this, because this isn't meant to be taken seriously.

 

I mean it, don't get pissy about this and that.

 

I don't need to mention that this is going to be a harem. I mean my boy isn't an eunuch, and his system literally summons beautiful girls that are loyal to him and you expect him not to hit that?

 

But fr, I certainly won't write this as some fast food harem, because that sucked so hard. 

 

The summoned characters will have their own thoughts and goals; they are not sex toys that will immediately want to fuck him or instantly become in love with him. They only have a degree of loyalty to him, but not to the point of stupidity.

 

This story will begin in ARC 3 after he was rejected by every candidate available at that time; he essentially is at his lowest moment, and despair is clinging to his very body, and thus the golden finger arrives!

 

It's the built-in cheat that most isekai protagonists have! If they have them, why not him?!

 

So he got his own, albeit very late, after he had his spiritual enlightenment, which means dying horribly multiple times.

 

Also, some summons are overpowered as fuck, the kind of beings that could rewrite, change and even alter the narrative of the story.

 

Basically, they can break the fourth wall.

 

But that's for later.

 

 

Subaru despairs and has entered a scenario where he's at a dead end.

 

After being rejected by Crusch for not having enough reason and proof.

 

Lowering himself to Priscilla only rewarded him with a heavy kick in the face, alongside with a criticism of how disgusting and pathetic he was.

 

He knew that, but what exactly does she expect him to do? 

 

Right after that, he was used for information by Anastasia.

 

Now that he was at his wits' end, no one was willing to give him any support, and the only thing that he could do was go back to Roswaal’s domain.

 

Hoping that he would be able to convince them: the villagers, Ram and most importantly, Emilia.

 

To leave the domain with them, because it's the only solution that he could think of, he was grasping at straws. 

 

With the merchant they found, he wanted to use his carriage to help the villagers from Roswaal's domain to evacuate to a safer place.

 

Because waiting any longer would certainly doom them, he had personally seen it with his own eyes after all.

 

The Witch Cult…

 

And that Archbishop of Sloth,

 

Thinking about that thing makes him extremely angry, but at the same time fear it.

 

And while he was thinking back about what happened in the previous loop, suddenly he felt a mild headache.

 

Like something buzzing inside his brain, it started as hazy, but eventually it got louder until he could hear a TV-static-like sound, buzzing through his head.

 

His first thought was that he had finally gone insane from the sheer desperation he was feeling right now.

 

No matter how cheerful he may look, he is outside; inside, he is quite literally experiencing a mix of paranoia, fear, despair and rage that he could release as long as the threat of the Witch Cult remains.

 

“It's a miracle that it took this long…” He muttered to himself.

 

Then, the static sounds became clearer by the time they arrived near the Flugel’s tree.

 

I…nstalling…s..ystem.. 

 

#&-##@--##*

 

5%..

 

8%...

 

15%...

 

Subaru was now starting to get anxious because he thought that he was going insane before; now, with this newfound clarity.

 

He truly became insane, because hearing voices in his head that weren't his is a massive sign that he's not quite right in the head.

 

The numbers keep increasing.

 

49%...

 

51%...

 

67%...

 

69%...

 

77%...

 

90%...

 

His anxiety couldn't be suppressed anymore, as he was visibly showing his discomfort, and Rem, who was behind him and driving their carriage, noticed and couldn't help but ask with concern. “Subaru-kun, are you alright?”

 

Subaru quickly gave his best impression of a harmless, innocent smile and replied.”No problem at all! I was just thinking what I would say to convince the villagers to leave the domain. I'm a little worried; that's all.”

 

“Ah! Is that so? Then you don't need to worry about it! I'm sure my hero could convince them with his words! I will also be with you when the moment arrives!” Rem smiled sweetly at him.

 

Making him very guilty about lying to her, but he couldn't just make her worry about him when it was his own issue.

 

Then the countdown finally reached its completion.

 

100%..!

 

Integrating the system..

Successfully imprinted to the host soul!

 

[ Heroine Summoning System is Online! ]

 

Then, without warning, a flood of information about this system was directly transmitted into his brain.

 

What's its purpose, how to use it and other things that he needs to be aware of.

 

Upon realizing that he wasn't going crazy and this thing wasn't a fragment of his insanity.

 

Without realizing it, his face turned into disbelief, then to shock, and lastly overflowing hope!

 

After all, the ‘cheat’ he has been thinking about since his arrival in this world has finally arrived!

 

He thought RBD was his cheat, but after experiencing the cruelty and suffering that it gave him. 

 

Subaru thought of it as a curse rather than a gift, because dying over and over again wasn't the worst part of it, but rather the feeling of being utterly forgotten.

 

The isolation was suffocating; he didn't know if he could take it any longer, but with this ‘cheat’ arrival. 

 

Maybe, just maybe, it could turn his life around with the help of whomever he summoned, because it's unbearable carrying this weight by himself.

 

Without hesitation, he opened his starter pack.

 

[ You obtain a Tier 5 Summoning Ticket! ] 

 

Based on the information that was transmitted to him, there's Tier 1, the lowest and Tier 10, the highest and above that isn't available or perhaps doesn't exist.

 

Tier 5 Summoning Ticket, which means the middle of the spectrum. Aside from knowing that it could summon a Tier 5 character, he actually doesn't know how strong they are, as it wasn't part of the knowledge he obtained from his system.

 

Then a ticket appeared right in his hand, which Rem didn't fail to see, and she gave him a look of curiosity. “What was that, Subaru-kun? That paper just appeared out of nowhere! Is that a new kind of Yin magic?”

 

Subaru only gave her a grin, a genuinely happy one. “You can say that, because this is going to be our ticket to victory!”

 

Although she was a bit confused as to why her hero thinks a mere ticket could lead them to victory, she smiled regardless upon seeing his happy expression, believing him with all of her heart. “Really! I'm relieved to hear that!”

 

And when they were having a nice moment, suddenly he noticed something off about the shadows beneath, because he could hardly see the carriage shadows and only saw a dark mass of something covering their carriage; not only them but others also had the same thing covering the shadows of their carriage, like something massive was floating from above…

 

Subaru stared up at the sky, but only he could see a massive mass blocking the moonlight reflection, and out of curiosity he pointed his phone at it and flashed a flashlight in its direction, and there he saw massive yellow eyes that stared directly at him with malice.

 

Immediately changing his expression changed from curiosity to horror in a single span of a second.

 

And as if it had been discovered, there was no point in hiding its presence anymore, and it roared as its massive body moved, creating a massive gust of wind knocking him and the other carriage around due to the sheer force.

 

“Ahhh!” He screamed as his body flew away a few meters from the carriage and rolled in the grassland near the forest.

 

Just like that, everyone was scattered around. He could hear others' screams as well, as the fog started to cover the entire place and it became eerily quiet, but he could see that the whale was directly looking for him.

 

Making him utterly afraid, he clenched the ticket in his hands, with his dear life as if it might as well be his last lifeline.

 

He prayed to every god that exists, hoping that whomever he summoned could help him with his current predicament.

 

He could hear it wailing, and to him it was a terrifying sound. Without hesitation, he ripped off the summoning ticket, and a flash of light appeared right in front of him, temporarily blinding his sight.

 

Then, as soon as he recovered, he saw a woman floating a few feet above the ground; her hair was long and braided, it was colored purple and shining in the dark, and there was a static of purple electricity around her.

 

She's also wearing a dark purple and lavender outfit that mixes a modern bodysuit and a traditional kimono.

 

A crimson sash tied into a large bow at her back, featuring a fan-like ornament and a tasseled symbol badge that he has no idea of.

 

Her small black shoulder guard with the same symbol on her obi, that was on her left shoulder.

 

Despite her traditional clothing, her dark purple thigh-high stockings with small diamond cutouts at the top say otherwise.

 

But aside from that, she was now looking at him, who was still on the ground, lying pathetically with a polearm in her hands.

 

Then he pleaded with her in a rather pathetic way. “Please! Help us! There's a monster behind you that would get us all killed if we stay here any longer. If you possess the ability to kill it, then kill it!”

 

The woman stared at him in silence above, then her lips parted. “Very well, summoner, if that's what you wish, I shall slay the beast.”

 

The purple woman turned around, then looked at the massive whale floating above her.

 

It was looking at her with its massive eyes; compared to its size, she was practically an ant.

 

Then it roared once more, making another strong burst of wind within the area, but the woman in front remained unfazed, as if the thing was not worth noticing.

 

Seeing this, the white whale became enraged and covered her with its fog, but it was useless, as a single strike from her polearm parted the entire fog of the whale, including the ones at the carriages.

 

Not only that, but it also injured the white whale’s face, making it bleed.

 

Making it roar in pain, it finally saw the woman in purple as a threat to its life.

 

But the woman paid no heed to its pain and continuously struck the white whale like it was her basic attack.

 

And a minute later, it was covered in wounds from various parts of its body. Realizing that it had kicked a steel plate this time, it decided to tuck its tail away from here.

 

But the woman in purple didn't intend to let it go, and now she was actually trying with her strike, as a surge of electrical energy gathered through her polearm, then she swung it hard.

 

It was as if the world lost its sound; next was a blinding white light that covered the area, as a flash of light hit directly at the White whale.

 

Whusssh!

 

BAAAAAAAANGGGGG!

 

A loud sound of thunder hitting its target echoed through the entire place, and the beast paused for a moment before its body started separating, and at its final moment only did it realize it was cut in half by that strike.

 

Blood rained from where it fell, and a loud thud was heard as soon as its bisected body hit the ground.

 

And for a moment, silence encompassed the place.

 

Then the woman in purple floated down right next to Subaru's still-lying body, who was looking at her in shock, and then she spoke. “I have killed the beast as you asked me to, summoners. Is there anything you would like me to do?”

 

Subaru was still gaping at her, unable to process what just transpired.

 

Then, without warning, someone started screaming in joy; soon, others started shouting in joy as well, for their survival and the end of the terror that was white whale.

 

And that's how the supposedly dark isekai fantasy turned into an easy wish-fulfillment isekai fantasy that he expected when first crossing over into this world.

 

Ding! 

 

[ You have achieved a great achievement for killing one of the 3 Great Mabeasts with your summoned character! ] 

 

[ Obtaining 2x Bronze Ticket Chests and a Silver Ticket Chest! ]

 

 

Welp, that's it for now. As you can see, I'm greatly inspired by Eastern webnovels, as you can literally see the flavor of them.

 

Anyway, before any of you ask.

 

Ticket Chest contains tickets, and each would give 1 to 3 depending on luck.

 

Each chest is tiered: Bronze, Silver, Gold, Platinum, Diamond and Legendary.

 

Bronze consists only of Tier 1-2 summoning tickets.

 

Silver: Tier 3-4.

 

Gold: Tier 5-6.

 

Platinum: 7-8.

 

Diamond: Tier 9-10.

 

As for legendary, well…I doubt it will be needed in the story.

 

Tier 1: Summon consists of ordinary folks.

 

Tier 2: Superhuman to Street Level.

 

Tier 3: Street Level to City Level.

 

Tier 4: City Level to Country Level.

 

Tier 5: Country Level to Continental Level.

 

Tier 6: Continental to Moon Level.

 

Tier 7: Moon Level to Star Level.

 

Tier 8: Star Level to Solar System Level.

 

Tier 9: Solar System Level to Galaxy Level.

 

Tier 10: Galaxy Level to Universal Level.

 

As you can see, even above Tier 6 could completely walk the Re:Zero verse sideways, and anything above that is exaggerated.

 

And you want to add the ones above Tier 10?

 

If that character ever appeared, it means it's not going to be in the Re:Zero world anymore.

 

And yes, if it wasn't already obvious, it's Raiden Ei.
