SISTERLY LOVE

Kanji Sashara’s annoyingly normal little sister, Keiko, has fallen for video game master Kousaka. And now she’s willing to do whatever it takes to steal him away from his girlfriend, Saki Kasukabe . . . even if it means becoming a fangirl herself!
But as a wise member of the Genshiken once said: “You don’t become an otaku by trying.” So Saki teaches Keiko-chan what dating a rabid fan truly means . . . and it ain’t pretty. Then, just to add to the craziness, there’s plastic modeling mayhem (don’t ask), the challenge of Kanji’s first PC, and Saki’s penchant for pyromania. Looks like things are heating up!
