That's fine, but your character has a number of high power techniques that would by all rights oneshot my guy if he were caught with them flush, considering Ikkotsu and Oni Dekopin are effective against the likes of Aizen and Wonderweiss, as well as the ability to block blades flush with his fists and straight up tear through rock, hollows and the like combined with regular expert hoho. 

And I'm not seeing anything about limited reiryoku and reiatsu, which means he could employ all those abilities that come with the aura release as well as giving him a general advantage in power and durability. I mean it's fine if that's what you want to do, I like your character and their type, I'm just saying it feels you're overly limiting yourself, especially considering what's been established as acceptable by other lieutenants.
