Shifu > Jinpu > Yukikaze in priority. Higanbana > Midare Setsugekka for Sen usage.

Hissatsu: Kaiten on Midare Setsugekka > Kasha, Gekko as priority.

Hissatsu: Yaten, Enbi, Hissatsu: Gyoten combo sequence might be worthwhile, in which case you'd want to do it on cooldown, assuming you have Hissatsu: Kaiten for Midare Setsugekka as that's the highest priority for Kenki usage.
