I really like the red/blue thing that Kawa and Umi have going on. Both of them contrast so well; both physically and in terms of personality.
This was literally the only reason why I bothered to farm for Umikaze (I ignored both Mizuho and Kazagumo), you can't have the Red Oni without the Blue Oni. Much like you can't have Yuudachi without Shigure
