Um, I had an idea for a Squad 5 Captain who's actually a genius at Kido but gave up on using it after he lost his eye in a fight and the sudden lack of depth perception and general decrease in long-range visual ability caused him to hit a subordinate with a powerful Hadou while fighting. So now instead he focuses almost exclusively on swordsmanship for his personal fights.

Also he would be ultra-manly and hotblooded, generally act like a silly loon and do things like picking up a new hobby every week because "A man's hobbies should be as numerous as the stars and burn ten times as bright!" for example, partially for fun and partially to throw people off as to his competence. Also I talked to Rin and she's okay with him being the person who initially taught her character Kido.

Hope that sounds okay.
