Ok, two more things. 1) there's a possibility that some events with Micosh's fighting costume are available before getting it (tho that might be a corrupted save thing or smth, I started new game but some things are already bought). 2) third event in twilight alliance. There were transformations (main quest ones) 1) on hidden counsel meeting, 2) Hell fight in dojo, 3) 2nd event in twilight alliance and 4) 3rd event same, and additional 1) Shella last available event and maybe 2) last Neon quest event (here I don't remember). So at the very least there were 4 transformations, definitely possible 5 and probably possible 6, and not 3 as it states in-game.
