This game is something else! first of all, all the characters are gorgeous! I find the story intriguing, and when stuff happens, it goes down hard. Just when you think this is just "another harem-collection game", the story makes flips, making the bold choice of locking out a ton of previously available content (at least temporarily).
Favorite character is definitely Kana though. she deserves all the headpats (as well as lil' Kana).
