The whole series features frequent sexual intercourse, oral sex and masturbation and revolves around a college student, Takakage.
The scene moves to modern day Tokyo, where the protagonist of the story, Takakage Takasaka, wakes up, realizing he has had a wet dream.
They go to school together and are met by Takakage's childhood friend, Mayumi Hiragi, who claims to be able to tell fortunes, and predicts that he's going to fall in love with a very beautiful girl that he is going to meet very soon.
Maiko: As the series begins she is introduced to the audience as Takakage's sister, who he cares about a lot and feels like his parents rather than his brother.
Either she couldn't kill herself cause of the spell, then she lived over 400 years and after she met Genshiro's reincarnation, Takakage, she falls in love with him.
En Hong finds that "The first episode is merely a conglomeration of scenes 'thrust' upon each other with a 'loose' plot to 'bind' them together" and that the production values are lacking, but noted it was effective as a hentai work, "accomplishes what it sets out to do (every girl that makes an appearance)".
[1] Chris Beveridge thinks that Campus is one of the "simple, but done well" titles from the Vanilla Series line, and points out the lack of "non-consensual scenes", not "terribly explicit" sex scenes, and "a focus on dating and romance" to make it recommended for couples' viewing.
It has character designs that are cute, if unusual, surprisingly decent animation, and a completely bugfuck time-twisting storyline.
