Does anybody know what I need to do to get the ending with the blonde Succubus? I... kinda managed to unlock every ending in the post-game room you end in (thanks to a number and a... Crystal ball?), so I know she got one, but I really would like to "unlock" that enemy's ending on my own. Been trying various things without success (I don't know much Japanese and this game showed me I should ç_ç). Thanks for reading, in any case.
