Haganai: I Don't Have Many Friends Vol. 4 (manga)

The antisocial members of the Neighbors Club waste their time playing bishoujo games, playacting, and getting into arguments about the geekiest things. Yet somehow they've managed to add seven members to their pathetic ranks.

Whether it's writing a round robin short story together - a seemingly innocent affair until someone goes berserk - or taking things too far in an MMORPG, these freaks take their fantasy seriously. But can a group of people so alienated from the rest of the world really make friends with each?
