If I may intrude again, if there are no other ideas, I would suggest something on the scale of Guts' Berserker Armor. Maybe, as he grows stronger, he can convert the damage done to him as a bolster to his own strength, while simultaneously being unable to feel the pain? Ofcourse, this would be more down the line, but you could give him a watered down version for his B rank. Maybe gain a temporary boost of power dependant on the wound? (slight: almost no change. Crippling: Tons of damage)

Edit: I've noticed that I've been butting in alot when it comes to problems in the RP. If it gets to be annoying or bad, please tell me and I will reign myself in :/
