From Kodansha:
It's spring of freshman year, and Kanji Sasahara has a difficult dilemma. Should he declare his love for manga and anime fandom by joining an otaku club, like he has always wanted to? Is he prepared to deal with the social stigma attached to being an otaku? Meanwhile, Saki Kasakabe has her own otaku conundrum. How can she turn her boyfriend, anime fanboy Makoto, into a normal guy? Kanji follow his heart as does Saki. When both Kanji and Makoto join Genshiken: The Society for the Study of Modern Visual Culture, Saki chases Makoto through the various activities of the club from costumeplaying and comic conventions, to video gaming and anime model figures. Saki finds otaku to be more than she imagined, but not necessarily in a good way.
