Nanashi sits with a small grin in an office with his parents and a very confused Doctor. The Doctor continues his rambling, "This is entirely unprecedented! His Quirk has almost nothing to do with either of yours! I've heard of genetic mutations, but this is simply ludicrous! The level of potential his abilities have is simply unbelievable!" Nanashi and his parents leave shortly after as the Doctor's rambling shows no sign of stopping.

Nanashi's father sighs, "Honestly, the man is supposed to be a professional, but he gets this worked up when something new happens? I'm surprised he still has this job." Nanashi can't help but agree, in this strange world the boy feels as if this kind of par for the course.

As the family heads home, Nanashi is excited to be able to summon his demons in this new world, 'Glad I'll be working with something I'm familiar with, don't have to learn too much more than I already know. I do kind of feel bad for the others though, they won't have as easy of a time learning about and expanding their powers.'

As soon as Nanashi gets home, he runs out to his backyard to test his powers. 'Okay, I summoned Centaur, so what else can I bring out at the moment? I've only just gotten these powers, so I should start small, weak demons first.'

Taking a deep breath, Nanashi calls on the knowledge of all the demons he's had dealings with, searching for the perfect candidate, 'Maybe a basic physical demon? Nothing too strong, but stronger than Centaur.' A smirk crosses Nanashi's face as he finds what he's looking for, 'Perfect! Just what I need to do this!'

Reaching for the demon with his mind, Nanashi raises his left hand and grasps his power, causing his eyes and the four leaf clover to ignite. However, nothing happens. Nanashi is confused, to say the least.

'The hell? I did nothing different from last time, so where is he?" Suddenly, a voice speaks out in his mind, 'What is it you want, boy? Why should I obey the likes of you?' Nanashi blinks and stand there a moment as the truth dawns on him, if he wants demons, he has to make deals with them all over again. '… Fuck.'

Taking a deep breath, Nanashi mentally prepares himself. 'Hey, demon, you're trapped in here, right? Don't you want out?' The demon gives a gruff snort, 'That sort of freedom comes at a cost boy, servitude to a brat like you. Why the hell should I do anything you say?' Nanashi thinks back to what he knows of this demon from it's mythology he studied, after saving the world of course. An idea strikes him, 'Well, I'm only likely to call you out for combat, so when I let you out you get to break something.'

The demon is silent, '… Alright, you've made your argument kid. I accept, now let me out, it's been ages!' A smile crosses Nanashi's face as the demon materializes before him, "Pleasure doing business with you, Fomorian." The shaggy goat demon gives a gruff snort, "Yeah, yeah, now then. Point me at something I can smash!"

Nanashi surveys his backyard and spots some empty wooden crates, assuming his parents won't miss them, the boy directs Fomorian right at them. The demon lets out a yell as he charges the boxes before headbutting them as hard as he can, destroying them immediately. Nanashi smiles as he recalls Fomorian into… wherever his demons come from, seriously, where do they go without a smartphone?

Before Nanashi can ponder too much longer, a wave of fatigue washes over him, 'What? Did I overexert myself already? But Fomorian is barely stronger than Centaur! Ugh, whatever, I need a nap.' Returning to the inside of his house, Nanashi collapses onto his living room couch and falls into a deep sleep.

(A Year Later)

Nanashi is, for once, excited about school. This is rather unusual for him, as over the years he's grown a non-insignificant level of hatred for the education system, mostly because he already knows most of the material. However, today is different, today he start elementary school. While he fully expects it to be as boring as kindergarten, the school itself isn't why he's looking forward to this. Nanashi is excited for elementary school, because there'll be a larger number of kids there, and that means an increased chance of bumping into one of his old world friends.

As he makes sure he has everything, he's suddenly lifted from the ground and placed an a strong set of shoulders. Nanashi can hear the smile in his father's voice as he speaks, "You about ready kid? We'll have to get going soon. Nanashi chuckles, "Yeah, I'm ready! Let's go!"

While they're making the drive to the school, Nanashi glances down at his left hand. Back in the old world, the markings on his hand had actually extended all the way up his forearm and even down the tops of his fingers just after the top knuckles, but here he only had the four-leaf clover on the back of his hand, and just a smidge of green on his pinky that had appeared after summoning Fomorian.

It appears that in this world the markings act as a gauge for how much power he can put out with his Quirk. A useful tool to monitor his ability's progress, but also a reminder of how painfully far he was from his original power. Nanashi looks up and notices that they've arrived, a smile breaking out on his face.

Making his way into the classroom, Nanashi immediately notices Asahi, and his smile widens as he makes his way over to her. He sneaks up behind her and taps her on the shoulder, "Nice to se-", he's interrupted as Asahi lets out a shriek, "Nanashi! Don't sneak up on me like that!" Nanashi can't help himself, he starts laughing. Asahi pouts, "Come on! It's not funny Nanashi!"

Nanashi raises an eyebrow, "Are you sure? Because I'm laughing pretty hard!" Before the conversation can continue, the teacher walks in and has them all sit down. Nanashi and Asahi end up sitting near Midoriya and Bakugou, but strangely enough there's an empty seat near them.

As the bell rings and the teacher begins taking roll, the sound of running footsteps echos through the hall and the door is thrown open. In steps a familiar head of gray hair, and Nanashi can't help himself. Standing up as fast as he can, a giant grin on his face, Nanashi waves excitedly at the newcomer, "Hallelujah!"
