Trio the Punch - Kamakura 1CC トリオ・ザ・パンチ

I FIGURED IT OUT (in Japanese) Kamakura + Katana Sub = Easy You can use 15hz frame 1 on or frame 1 off auto fire set-ups to manipulate the roulette fairly easily. Frame 1 on = sub up, frame 1 off = life up. Most bosses can take multiple hits if they're off the ground, so katanas travelling upwards can tear through a lot of them.
