Shuichi's a third-year high school student who just wants to live a normal life and keep things exactly as they are. The problem? He's terrified of himself because he can turn into a monster.
His transformation ability is pretty wild—he morphs into a mascot-like creature that gives him enhanced strength and a sharper sense of smell. The weird part is that his body has a zipper. Someone can literally unzip him and climb inside, taking control of his body while he's in that form.
But here's where it gets interesting: if Shuichi and whoever's inside him share the same goals, they can actually work together. Instead of it being a takeover situation, they can fuse into a single being where their souls, bodies, and memories all intertwine. When that happens, they're able to push past their normal limits in ways neither could achieve alone.
It's the kind of power that sounds amazing on paper, but it's also the reason Shuichi's so anxious about himself. The transformation, the loss of control, the possibility of merging with someone else—it's a lot to handle when all you're trying to do is graduate and blend in.
