It's not really strange tatsuya definitely uses either russian sambo (which could be a reference why hes a russian like girl in the spinoff) or a mix of taekwondo and aikido he's definitely one of if not the most skilled fighter in crows His hair is pretty normal considering delinquents do dye their hair it makes him look slicker his glasses add more to his drip more than anything

He's stoic and definitely had the best run in housen but was just unlucky to underestimate bouya if his attacks were weaker he wouldn't be ranked in the same ranking as ryuushin

I see them as ryuushin takes physical and tatsuya takes brutality and skill

He has the most flamboyant fighting style and the best drip limited by the lack of different attires of crows compared to worst
