I'll probably go with Kaneki. Been on an anime binge lately, and Tokyo Ghoul is a favorite. I'll probably go through a few ideas that I love, and rig up some code to "pick a name from a hat". Simple programs like that are always fun to make~
I plan to name the MC (when i play) Dian from the word guarDIAN it's a very symbolic name to my family, but I feel that maybe one of the secret characters might suit the name better.
Just a thought. What if there was a special cut scene or like name denial of matching names like they did in undertale where you couldn't use names from the other characters like Sans. So maybe if your name is Shiba or Shuu it'll bring up a cut scene or something. Just a passing thought
