Atsuro will be the one I play with during this event! I think it's a good opportunity to have him confront some of his issues that would never normally get out in the open.

Atsuro generally has issues with being abandoned since his parents basically ditched him to raise himself/be raised by the Internet or something equally not-responsible. Part of why he's friendly and social is because the thought of not having friends does scare him. And definitely part of why he's so loyal is because he would hate it if anyone ever ditched him, and he isn't going to do that to anyone if he can help it. He doesn't like to admit it, though - he presents as pretty confident, because mostly, he is. He managed to raise himself fine, he has tons of friends, and he's got tons of Internet friends too so it's like he has twice as many he's totally cool.

His Shadow and the part of him that he doesn't want to accept will be the part that's clingy and needy and afraid of being ditched, basically.
