Would my character survive in your characters canon?

he would probably survive better then he did in his own tbh

would probably try to join sword boys on the battlefield

he gets a mobile suit with the biggest sword

Probably. Depends on who he runs into first, like one of the nicer youkai or human incident resolvers.

i could see nmj being a sect leader in word of honor, he already reminds me of a character in it lol

he would just be considered a weird and dedicated cosplayer lmao

He's got like a 50/50 shot in Onmyoji I feel like.

Depends on how "involved" he gets in world events.
