-CV: Tomokazu Sugita (JP); Patrick Seitz (EN)
-has code of honor about a regret of using his lethal attacks to hit female's beauty parts, the blames on him
--but can only use a certain conditions (mostly using fishnets, spank the butt, can only use his fist to smack female's upper head from above or behind)
--except against those who are purely evil/injustice from within, or has a strength & bruising attitude that truly pars with males, but respect each other
-the reason of having a code of honor was because some reasons what happened back in his childhood which had him comically abused by a certain blonde childhood female friend of his/Tina (can be considered as Kohaku (from Type Moon's Tsukihime/Melty Blood) of the series) who puts him into thigh grapple related submission moves (like armbar, leg lock, sleeper hold, headscissor & triangle hold) sexually, but clean (messing with his ball would be hell on earth), turning him into a masochist when the submission takes longer or through clean sex (kiss, hug, thigh grapple, putting face between breasts, ear bite, neck lick, cheek lick, & blood sucking through neck bite) as a guilty pleasure, particularly while wearing too revealing outfits besides skimpy bikinis makes him shy, quick face burn/steamed and quick blood puke, gives him even worst when come near wearing that outfit. The girls kissing him tightly makes him completely drunk, turning him into a Yu Narukami in his King Game mode & suddenly move its own through having the girls do clean sex on him tightly. try his best to stay out of trouble because of this problem
--This spreads through most of DOA female casts
---except Mila (tsundere & very sane how to use it for), Christie (not doing it, but fun to watch), Rachel (mostly sane & the only female he can fight due to some that made her too strong and par with male's strength + considered like a sibling instead being attracted each other & not really a girlfriend/boyfriend material), Nyotengu (sometimes, but also goes to some DOA male who is not Ryu Hayabusa) & Helena (sometimes, but sane & only watching)
---but not counting those who are truly evil like a mindless female monsters (such as Alpha-152 & some mindless clones (safe for Phase 4 whose under his care))
---while for the rest like Lisa (whose married some of new protagonist's friend, but sometimes uses only submission moves on comically torturing protagonist), Ayane, Lei Fang & Hitomi are only attract to some DOA males
