Hey. This is Kate from the mod team, here to answer your questions.

As far as the Hitomi goes, because there are three sets of kanji all with three different translations and one pronunciation, we assume that most Japanese speakers will think of it as "Hitomi," i.e. the pronunciation that they all have in common. You're free to play around with this if you want - we certainly aren't going to tell you how your character will think, and it makes sense that some will think of it differently.

As for the second point, it's actually fine. At the moment we do have a nerfing system that comes into play when someone is engaged in actual battle - so if your character has an instakill move, he'll have to go without it when fighting another PC except in special circumstances. I actually played a character who was similarly absurdly overpowered, and I managed to work things out well enough with her. The mind/emotion reading thing is fine, although we ask that when you intro into the game you make a post warning people/asking for permissions. I would encourage you to go ahead and app this character. I don't forsee any issues from what you've described.
