Junjou Romantica: Takahashi Misaki is suddenly having some unexpected and odd problems. What started as a need for some college entrance exam tutoring has somehow led him to being romanced by a suave older man who also happens to be his big brother’s best friend. Confused by all of his brand new emotions, Misaki struggles to deal with his suddenly very odd life. And if that wasn’t enough, his suitor, Usami Akihiko, has plenty of issues of his own. A man-child who decorates his room in giant teddy bears and toys, Usami is a famous novelist who also writes steamy boys’ love novels on the side. When Misaki cracks open one of these books and reads sentences like “Usami licks every inch of Misaki’s hot body”…well, let’s just say that all hell breaks loose.

Junjou Egoist: Kamijou Hiroki is a broken man, consumed by unrequited love for his childhood friend, Usami Akihiko (the writer from Junjou Romantica). Along comes Kusama Nowaki, whose name "Nowaki" means "typhoon", an orphan working his way through life since middle school. Like the typhoon he is named for, he whirls into Hiroki's life and heart, blowing all resistance away before him.

Junjou Terrorist: As fate would have, Miyagi, Yoh (The professor Kamijo, Hiroki works for as an assistant professor) and Takatsuki, Shinobu, Miyagi’s bosses son AND his ex-wife’s brother, would cross paths. Shinobu, who says whatever’s on his mind, tries to break into Miyagi’s world, saying things like, “its destiny!” While the 17 year old tries to invade Miyagi’s peace, the 35 year old is still lost in his dramatic past of his love for his late teacher, a past he thinks that will never stop lingering. As the Terrorist he is, Shinobu invades and destroys Migayi’s daily lifestyle, dramatically changing the Professor’s heart, making the older man’s heart grow into something new, as it’s destined to be…
