You backed up, placing your hands on your hips.

"You said you could handle it, right Nanami?" You said. "Take the floor." Mahito's eyes went from you to Nanami, obviously trying to figure out if it was a trap or not. His feet and lower legs turned to hooves before he launched forward, faster than before. Oh--he can transform his soul. His body follows. You catch on quick. It's not hard to comprehend. Mahito engaged Nanami in a chase--despite missing an entire arm. The two of them ran deeper into the sewer before Nanami jumped down into the central area. You followed behind them casually, stuffing your hands in your pockets. That's when you noticed Nanami going into overtime. Removing his tie, wrapping it around his hand, and his cursed energy was increasing dramatically. Mahito was sitting on the railing in front of you.

"Fun!" He exclaimed, jumping down to the bottom. You walked up closer and leaned against the railing. Nanami led Mahito back on a chase throughout again.

"Nanami's sort of attractive, isn't he?"
You didn't even bat an eye.

"Didn't know you went for the serious type," you replied. Kuragari laughed, putting her hand on your shoulder and walking to the other side of you.

"Not usually," she replied. "But the thrill of getting someone like him to submit sends tingles down my spine." Your brow twitched.

"I didn't need to know that."
Kuragari grinned.

"I know your type though."

"I will exorcise where you stand."

"Right, right." Kuragari disappeared when the entire area shook, filled to the brim with cursed energy. When you actually paid attention, the wall to the room was broken, cursed energy flowing through it. Oh... shit, am I in the way of it? You looked further and noticed Nanami cut Mahito's one leg off, trapping him. The wall was about to crash down on them. You appeared in front of Nanami and grabbed his wrist, disappearing from the sewer faster than what he could've done. You appeared outside the lair--and with a sigh, Nanami went slumping forward. That's when you noticed blood stained through his shirt. Ask him to pull up his shirt and heal the wound. No.

Nanami clutched his wound with a quiet grunt. With a snap of your fingers, Nanami disappeared from the area. Where'd you send him? Don't worry about it. Let's just go back before anyone asks questions.

Geto and Mahito stood on the roof of the school building, casting a curtain over the area.

"Hey, I did it!" Mahito exclaimed in awe.

"Thanks, Mahito," Geto thanked. "I can't afford to leave any residuals of me behind."

"Oh, you're worried about residuals, are you?" When the two turned their heads, Kuragari was floating next to them, upside down. Her signature chesire grin was on her face.

"Kuragari Kanzaki," Geto acknowledged, his expression dropping.

"Why does everyone always say my first and last name when seeing me?" Kuragari flipped, gently landing on the building. "Well, it doesn't matter."

"An unannounced veil in a residential area," she spoke. "The windows will report it soon."

"So? Why are you here?" Geto asked. "If you were going to stop us, you would've done it already." Kuragari glanced at them, her face splitting into a wide grin.

"It's not my place to stop you," she said. "I'm in a bit of a bind, you know." She raised her arm, and a metal cuff appeared before the long chain. It rattled when she moved.

"Oh--your vessel," Mahito said. "What was her name? Y/n?"

"Speak of the devil and he shall appear." You appeared on the roof, holding the end of the chain. "You lived. Unfortunate." Kuragari giggled before disappearing behind you. You looked down towards the gymnasium.

"You both think y'all slick, huh?" You walked towards the edge of the roof, turning to face them. "Hope you're quick thinkers." You fell from the ledge, disappearing before hitting the ground.

"Well that might be a problem," Geto spoke lightly.

"Isn't there a way to distract them long enough to get them out of our way?" Mahito asked.

"No one matches their strength," Geto replied.

"Oh... I have an idea." Mahito licked his lips.

Standing on the school grounds, you already knew Itadori was inside--despite Nanami telling him not to. Bonehead. Looking up, you saw a young boy getting thrown through the window, along with his shikigami. Well that's peculiar. He landed on the metal roofing below, his shikigami cushioning his fall. Your brows raised. You jumped up to his level. He threw a glance at you, but then did a double take.

"You...!" He gasped out. "You're...! Kuragari Kanzaki!"

"..." You blinked. "Alright, just for that--" You suddenly appeared in front of Junpei, watching in satisfaction as his eyes widened in shock. Your fist connected with his midsection, sending him flying into another section of the school.

"Y/n-senpai!" Itadori jumped down behind you. You looked back at him and jerked your head in the direction of where Junpei was lying. He ran past you and through the shattered window frame. You rubbed your face, tired. ... I just kicked a child, didn't I. Yep, and it was glorious. You sighed. Man... why can't I just kill everyone and be done with it? That sounds like 102 year old Y/n. Shut up. You calmly walked over to the side of the building and stepped onto the window frame. Just in time to witness Itadori being slammed against the panes by an augmented arm. Standing behind Junpei was Mahito.

"God, you just don't give up, do you?" Using your cursed energy, you twisted and ripped the arm apart, releasing Itadori from its grasp. Immediately, Mahito placed his hand on Junpei's shoulder. Isn't that a predicament. Mahito didn't waste any time. He transfigured Junpei's soul--much to Itadori's dismay.

"Now, time for round two," Mahito said gleefully.

"Great, time to do this again..." Your head turned, eyes looking out from the window. What was that? Was what? I wasn't paying attention. Thoroughly ignoring the others at that point, you stepped closer to the window. That cursed energy. It felt like it came from a L/n.

Ja ne!
