d-frag, D-FRAGMENTS, ディーふらぐ!, D Frag, D-Fragments!

The Kazama Family-a trio of aspiring delinquents who are close friends and led by Kenji Kazama-are attempting to make a name for themselves at Fujou Academy. On the first day of term, while trying to start their year off on the right foot, they find themselves putting out a fire in the Game Development Club. However, instead of being thanked, the eccentric club members attack and knock out Kenji's two friends, forcing him to fight for his life. Despite failing to escape, Kenji is coerced into joining the Game Development Club. As he settles in, Kenji gets to know the four girls responsible for his provisional membership-Chitose Karasuyama, the student council president and general tyrant; Sakura Mizukami, a spirited tomboy; Minami Oosawa, a negligent club advisor; and Roka Shibasaki, the school's infamous shadow leader. Throughout the constant shenanigans of the Game Development Club and his desperate attempts to leave the club, Kenji begins to realize that he may be actually enjoying himself.

D-Frag! adapts content from the first 5 volumes of Tomoya Harunos manga of the same name.
