Jinei has been training in the way of the bushi for some time now. He usually is very peaceful unless he has to fight. He is the leader of the Shinsen Gumi and his ties with them and honor are strong. He is usually very gentle unless fighting where he seems to change into a different person.
Jinei,for the past few years, has been studying The Art of War, and other battle tactics. Any other information on Jinei Shinomori to this day is unknown.
