Feeling confused, he trying to recall what happened to himself, only to find that he has two memories inside his head! After being freaked out for few moments and trying hard to reorganized his two memories, he realized that he actually has been reincarnated into a seventeen years old teenage boy! And the shocking thing is that he reincarnated as a fictional character! And that character is none other than the antagonist-turn-protagonist, Misogi Kumagawa from anime and manga called 'Medaka Box' written by Nisio Isin. But the shock is not over yet. When he investigated the memory of the current Misogi Kumagawa, he found out that what was this Kumagawa experienced until now is different from what he knows from the anime and manga! And how the heck he meet characters from different anime and manga! He even befriend three protagonist from three different harem anime and manga and become his classmates no less! He fell into shocked silence after knowing this and then starting to contemplating his life. But suddenly, he was interupted by something more surprising as a blue holographic screen interface appeared in front of his face. *Ding* *Congratulations!
