Inkei

He's abnormally large and buff for an ikenuma- ...which about translates being the height of an average person. (5'6)

His full name was Inkei Shinpitekina, but he abandoned the last name alongside his former life of villainy. Trying to move on from his past, now working as a bartender.
Translates roughly to "Penis Mysterious."

Uses blood transfusion in battle and general blood-related and HP-sucking attacks to fight, instead of MP.  Has negative girl power due to his masculinity. Strong and tanky but dislikes using his fists.
Can hardly handle sight of violence or blood, which is also funny due to his experience as a surgeon...
