If you spend any time on the internet at all, you have probably seen Nanaca-Crash. This bastard love child of Pingu and Hentai (it's actually based on a 'mature' Playstation 2 game) is slightly more addicting than smoking crack in an Orgasmatron.
Sadly, since the game is in Japanese, most people playing have used the randomly click like a maniac strategy since they have no frickin' clue what the hell is going on. Well curse that Stop Girl bitch no more, 'cause now we have some instructions!
Still no clue what the hell any of this means, but hey, that's pretty normal for anime.
