Etsuro is a loner who does not leave his place. He is isolated, has no friends and suffers emotionally after failing to gain acceptance into college. He attempts suicide, but is even a failure at that. He happens to see the girl next door and she tickles his fancy. The problem is she is a killer - no not a killer babe, a killer period. Nonetheless, he is cool with it and they begin dating. Is he safe or does she have plans for him as well?—aghaemi
