I'm at the level where I can beat Bunny Witch with just normal caresses lol. I have 100 in all but Luck and Magic (counting item buffs and perks)...
AFAIK I've seen every possible scene in the game, both losing and winning battles.
My favorite girl is still Kotone though. Genuine character development in a porn game? Sign me the fuck up. Also her hypnosis stuff was really well done lol.
