Hogwarts
"What do you have there Hedwig? How was your flight?" I ask my familiar. Looking at the envelope tied to her leg, it's a letter from Uncle Shouta in Japan. Removing it from her leg, I head up to the Gryffindor Dorms, to read it in peace and to take out the really shitty hearing aids that barely work around magic. 'Harry, I'm writing this letter to inform you that I have finally persuaded Petunia to sign custody of you over to myself. I'll be flying out tonight to London to pick you up there at Hogwarts. I should arrive there sometime during the afternoon, three days from the day you receive this letter. We'll stay in London to pick your passport up from the bank, and to have your quirk reevaluated. Due to circumstances, I have received permission from Nezu to have you join Mahoutokoro for lessons. With care, Shouta'. I get to see Uncle Shouta every so often over video chat, especially during what would be his class time if he hadn't expelled everyone in his homeroom this year. Luckily, we use Mirror phones, which work as cellphones in the Magical world, though mine is made by one of Shouta-ojisan's coworkers, Majima-sensei.
Professor McGonnegal enters the common room about an hour after I finish the letter and pack it in the hidden compartment of my trunk to escort me to Dumbledore's office to speak with him. "I'm very glad to hear that your mother's younger brother has finally gotten custody. I was the one that managed to help persuade your aunt to sign the papers. I do wish you would be able to finish out the school year but I will be sad to see you go." She says. Upon reaching Dumbledore's office, she and I are joined by Professor Snape, the only teacher that knows about my quirk, and only because he has a Pro License himself. Dumbledore attempts to persuade me to stay at the Dursley's and at Hogwarts but I refuse. I'm released back to the dorms, and I spend the next two and a half days packing and saying goodbye to my friends. The morning of the thirteenth, I'm sitting in the Front Entrance waiting for Uncle Shouta, who is finally escorted in by Argus another Quirked staff member. "Have you got everything Gremlin? We've got three days before we have to be back in Japan, and I plan on making the most of it." Uncle Shouta says, wrapping his hand back into his Capture scarf. I've never seen him in anything other than his hero uniform, or pink sweats, but he's dressed in a suit with robes over it. "I've said my goodbyes, and I've got everything I need in my trunk. I've sent Hedwig on where she'll take breaks as much as possible until she reaches Beijing's Gringotts's Branch so they can have her sent by Carts to your branch. I've merely got to arrange for them to transfer my current manager to yours instead Shota-ojisan." I reply in Japanese.
It takes us twenty minutes to pass Hogwarts gates, where oji-san tells me to grab onto his shoulder. One agonizing trip later, I bend over to try not to hurl as he explains that that was apparition. For the next few months after everything is settled down having taken a plane back to Japan instead of using a portkey, Uncle Shou's life partner and he teach me to get the full extent of both my magic and my quirk under control. Entrance exams are just around the corner, and Nezu-sensei asks if I would like to use my technopathy to act as scorer for the exams. I agree, and keep my eyes on a small green teen just slightly taller than me who winds up with almost nothing but rescue points. "I want the green one in Ground Beta in my class. His files reek of coverup and his stature reads of abuse on top of some severe quirk issues." Uncle Shou growls. Nezu-sensei agrees, and I catch All-Might wincing from the corner of my eye.
