Chapter Text
The plan was simple. Sneak into the kitchen, snag a plate of chocolate cookies, and bring them to the two bedridden demon slayers. However, things didn't go at all how Nezuko planned. Now, she and Senjurou are hiding behind the counter, waiting for Aoi to give up her search for them. She wishes Zenitsu was around, at least then she could whisper for help to distract Aoi! An idea pops into Senjurou's head, and he gestures Nezuko to get ready to run in a moment. The boy takes off his slipper, and waits until their hunter is in another room. He then throws the shoe as far as he can, making a sound at the very end of the hall. Aoi mistakenly believes that she's found them, and goes to where the slipper fell. In the span of only a few seconds, Nezuko bolts towards the cookie tray, grabbing it and running as fast as she can alongside her friend. Sweating from fear and exhaustion, the two bolt into the room that their friends are staying in and lock the door.
"Aw hell yeah, chocolate!"
Genya immediately digs into the cookie platter, leaving crumbs around his mouth. Muichirou's eyes widen, and he smiles as he takes a cookie.
"Mm, still warm... Hey, you stole these, right?"
Nezuko tries to think of an excuse, face red from being caught immediately. Genya swallows down a chunk of chocolate, shrugging.
"Eh, I don't really care where they came from, these are good!"
The four all laugh, feeling carefree for the first time in a while.
Only a month ago had they been closer to death than ever before, barely making it out alive from a battle against upper moon one. Nezuko had refused a serum to turn her human, sensing that she would need to be able to fight in the near future. She was right, as just a day later, the final fight against Muzan Kibutsuji took place. At some point, she and her brother get separated. She runs into Genya and Muichirou, before coming face to face with a demon far more powerful than her. By now, she's aware of Genya's strange ability of consumption, so she yells out to him while the Mist Hashira faces off against Kokushibo.
"Bite my arm!"
Genya knows that she's a demon, meaning not only will he gain powers from eating her, but she'll also recover fairly quickly. He runs over and sinks his teeth into her exposed forearm, which heals instantly. She focuses on the opposing demon, as her body grows in size and power. Now able to fully control her true demon form, she hopes to defeat Muzan and his subordinates once and for all. Nezuko dashes towards the demon, fangs bared and claws ready to slice. Genya loads his gun, firing at Kokushibo from behind a stone pillar. It slices at Muichirou, severing his arm from the elbow down. He yells out in pain, but pushes through and continues to grip his sword. Nezuko feels a blade pierce through her torso, making her cough blood onto the demon. She smirks at Kokushibo, confusing him, before activating her blood demon art. Bright pink flames engulf both demons, though only burning the flesh of one. The upper moon jumps back in pain, infuriated by this girl's insolence. Muichirou uses his remaining hand to swing at the demon, plunging the blade into it's chest. Genya lunges towards the monster, his short sword raised in the air. Nezuko sees a demon blade closing in on him, and jumps in front of the attack. She screams out in agony, as her body is ripped in half. Even if she can regenerate, it still hurts like hell..! Thankfully though, Genya is unharmed, and lands his attack against the demon. His blade sinks into it's neck, but the flesh is too tough to cut through. Nezuko uses all of her strength to heal her body, and grabs onto the other side of the sword. Together, both of them push the metal into Kokushibo's neck, while being stabbed and sliced all over. The younger demon uses her blood to create an explosion, giving the last bit of force needed to finally behead the monster. As the upper moon fades into ash, Nezuko turns her attention to the bleeding Hashira. She grabs his disconnected arm, and pours her blood onto it. Pink fire licks at Muichirou's skin as she sticks his arm back into it's proper spot, which disturbs both him and Genya. What's even scarier, is that when she stands up, he can move his hand.
"Wh... What the hell?"
Before they can ask Nezuko how she was able to do that, she falls onto the floor. Her body returns to it's normal form, as she sleeps to rest from battle. Genya and Muichirou sit against the wall, exhausted and proud. Little do they know, had it not been for Nezuko, neither of them would still be breathing.
"I don't care if you were trying to do a good deed, you stole an entire platter of cookies! Unbelievable, honestly!"
Nezuko and Senjurou sit in shame as Aoi berates them, knowing that they deserve it. Muichirou gives them a smug grin from his bed, holding back laughter as the angry girl leaves. The demon sticks out her tongue, matching his level of childishness.
"Those cookies better have been worth it!"
Genya chimes in, having been somewhat zoned out up until now.
"I'd say they were! Although, I'm still hungry..."
Nezuko giggles, giving him a joking smirk.
"Hey, why don't you take another bite outta my arm then?"
She and Muichirou laugh, Genya rolls his eyes, and Senjurou looks at the three of them with concern.
"Wh- What do you mean 'another'?!"
