From the Animeraider:

Have you ever read a manga and thought to yourself, "Why the hell did he do that? It's not what I would have done. I could do better!" Well, now here's your chance. This manga changes storyline depending upon choices you, the reader, make. Have fun!

Do not confuse with Gaccha Gacha.
