Oh I should add, because he's a bit tech illiterate an outdoor game where you charge from place to place with a distance counter and get lost is far more him. He might even enjoy it the first couple times. It gets soul crushingly boring fast though.
My instinct is to keep it a secret. You know, like every kids book and TV show where they keep their superhero book friend hidden in an abandoned shed in the woods or something. I wouldn't leave him in a shed, but him being able to come and go through the window at night would be convenient. At this time of year when it's cold he could camp out in the local library invisible to the living and stay warm, and in the summer I'm sure there must be somewhere with air con in town. Maximum freeloading.
There's something juicy about secrecy. Even if I introduced him to people, my temptation is to talk about him in vague terms without letting slip anything. I mean, it would be crazy to just out and go 'yeah he's a shinigami from teh mangos'. But surprise Japanese boyfriend with purple eyes? Yeah, that's curious.
Music isn't something I would think about too hard. It'd be whatever I was listening to at the time, but if he were there to hear it too I'd self-moderate what kind of music it might be. Especially since he'd understand Japanese better than me.>>3422916
I remember when the No. 6 anime was airing a classmate got excited when she found the novels in a French supermarket near her grandma's house. I can imagine Nezumi being a little smug that of all countries his books were widely available in France.>>3423490
I've done his alignment with online tests so many times and yet I always forget the results. Chaotic good? He has good intentions and believes in morals, but his methods aren't the best and he has trouble obeying law/authority if it conflicts with them.
He's so bad for risks I used to associate a song about being in harm's way with him.
He makes a show of himself to disguise the real point of concern.
