Otsukare, just cleared as well. I only had a fun time because of Siete & lotta but I'm curious how other people would manage without one or the other (or both). The xx skills omen sounds tough to clear without Siete FC, and I nearly had a bad time with back to back 30+ hits.
I got a "free" setup able to clear it, in theory. Dunno if and when I'll be able to record it, no time for now. The fight isn't that bad to be honest, just a bit boring mechanic wise.
