The third president of Genshiken. At first in denial about his otaku nature, Sasahara eventually accepts and embraces it. He loves hentai PC games despite not owning a computer until volume 3. When Sasahara assumes the title of Genshiken president from Madarame, his first decision is to push the club's initiative, and establish their own booth at Comic-Fest. While Sasahara is pretty much the "normal" otaku, his unwavering loyalty to a single character (Kujibiki Unbalance character Ritsuko Kübel Kettenkrad aka "The Chairman") makes him stand out from the others. Even the dōjinshi created by Genshiken under his leadership is a Ritsuko-themed one. Sasahara gives up being president during his senior year in order to focus on studying and finding a job, and passes the title on to Ohno.  While Sasahara starts off as a quiet, reserved member of Genshiken, he transforms into a somewhat stronger-willed individual, especially during his presidency. While not completely confident in himself, he is able to find a job as a manga editor and even fight back his own doubts in order to confess his feelings for Ogiue. As of the end of the manga, Sasahara is still dating Ogiue, and accepts the fact that she is using him as a direct model for dōjinshi. Sasahara also helps Ogiue by providing criticism and being an unofficial editor for her work in general, despite the possible risk to their relationship.

Sasahara Kanji is a college freshman who decides to join a student society to share his hidden thoughts on manga, anime and gaming. 
When he first visited Genshiken, short for "Gendai Shikaku Bunka Kenkyuu Kai" (Society for the Study of Modern Visual Culture), his groundless pride was destroyed by the plotting of Madarame, a sophomore student in Genshiken, but he still couldn't admit that he is an otaku. 
However, as he participates in society activities such as visiting dojin (private publishing) shops and anime festivals, and hangs out with other society members Kosaka (a hardcore otaku despite his extreme eccentricities and good looks), Kosaka's girlfriend Kasuga Saki (who isn't really an otaku), Ohno (a cosplayer) and the others, he opens his mind and resolves that he will make his way into the otaku world. With their help, Sasahara slowly adjusts to otaku life in Genshiken.

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?

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 cosplaying and comic conventions, to video gaming and anime model figures.

The Society for the Study of Modern Visual Culture, otherwise known as Genshiken, is now under the charge of a more confident Sasahara. Things have changed in between semesters, and the otaku club now has a new otaku-hating member named Ogiue. Sasahara's initial goal of starting a doujin circle and selling those fan-made magazines at the next Comic Festival becomes a reality, but reality is a cruel master... who apparently crossplays. Afterward, the club is abuzz with talk about Tanaka and Ohno's relationship, which takes a hesitant step forward.

It's a new semester at Shiiou University, and for "The Society for the Study of Modern Visual Culture," AKA Genshiken, that can only mean one thing - new freshman recruits! Originally founded as a club for otaku to discuss their unabashed love of anime, manga, and video games with one another, the current president of Genshiken, Chika Ogiue, may have bitten off more than she can chew by recruiting a bunch of yaoi-obsessed fujoshis to join their ranks! Meanwhile, the original members of Genshiken who have since graduated find themselves coming to terms with their new lives as productive members of society.

A new academic year means new members for the lovably misfit Genshiken: The Society for the Study of Modern Visual Culture! Club president Chika Ogiue now has to manage a fresh-faced trio of yaoi fans (one of whom dabbles in cross-dressing), a surly American transfer student with a penchant for obscure anime quotes, and her own rising career as a professional manga artist. Can she actually find time to draw her own vanity project for Comic-Fest?

Note: Genshiken Nidaime ("Second Generation") is a continuation of the previous series, with chapter numbering starting at 56. In the Japanese edition, the first volume of Nidaime is numbered Volume 10, to continue from the end of the 9-volume Genshiken series. The US edition renumbers the volumes so that the "Second Season" starts with Volume 1.

It's the start of a new year for the Genshiken crew, and that means recruiting new members. Always a dreaded task, The Society for the Study of Modern Visual Culture manages to get Chika Ogiue pushed onto them from the Manga Club. With her introduction of "I'm Ogiue and I hate otaku", this year certainly will be anything but boring.
