Just came back to playing this.
Beat up Final Boss V2 (BARELY won, it was p.cool, lv218 reimu or something) cleared out 25F, now going off to school.
Sadfacing because I don't have anyone I wouldn't mind replacing out for Yuka, although admittedly I only want her for being cool and not for being actually USEFUL, although she's certainly got some good points about her.
Then again, 2/3rds of my team is support characters, backups for eachother and with good tankiness. It's pretty effective, but it gives me a very small amount of wiggle room for picking my offensive characters.
