Y/N character sheet (please read)

What would happen if Saiki Met someone more powerful than him?

I really like this Y/N because the idea of being a dimension hopping reality warper just sounded so cool and I'd love to be in that situation so I made Y/N. But despite being silly goofy and op they got flaws as anyone else does and despite being so powerful there is a struggle for normalcy and constantcy in a seemingly perfect live and as we dive deeper they're going on a journey about themselves as they build bonds with someone of the same struggles.

Various x reader insert (i feel like it would def lean towards Akechi. Talkative lil lad. Love him)

Edit: it's definitely Akechi Touma x reader. I love him. He needs more screentime.
