Kaede Mizumori, a high school student who can see through people's lies, lives a dry life so as not to make waves. Until he meets the mysterious schoolgirl Rin Homura --- a thin sci-fi alien drama.

Meet hard-boiled cop Boyle Samejima. He's just been assigned to the remote Ogasawara Islands. There he finds coworkers, a mysterious young girl and a dolphin for a partner?! Cop x girl x ocean! Welcome to the craziest hard-boiled cop story you'll ever read!

A legend says that the ghost of a girl stands on the top of an old Catholic church, inhabited by the Sagimiya family. Said family has a hateful rivalry with the Bijogi family, who manage a Taoist temple next door. In the middle of all this, Bijogi Taiga has had a crush on Sagimiya Anna, the demure daughter of the priest, since childhood.

Little did he know, the Sagimiya are involved in very un-Catholic activities such as trying to resurrect the spirit of Marie-Thérèse Charlotte, the food-obsessed daughter of the late French queen Marie Antoinette. And since he has found out, he will have to "collaborate" − i.e. be the human sacrifice to that end. Nevertheless, just before the "ritual," Taiga decides to confess his love to Anna and is struck by a lightning bolt the second after. He miraculously survives without a scratch, but somehow finds himself in a body slightly more... blonde and feminine.

Comical sidestories from within the main series' timeline and featuring some new characters.

Two Brothers are climbing a mountain to learn a secret fighting technique from an old man. Three years later they are returning to their village ...

Ishiyama High is a school populated entirely by delinquents, where nonstop violence and lawlessness are the norm. However, there is one universally acknowledged rule—don't cross first year student Tatsumi Oga, Ishiyama's most vicious fighter.

One day, Oga is by a riverbed when he encounters a man floating down the river. After being retrieved by Oga, the man splits down the middle to reveal a baby, which crawls onto Oga's back and immediately forms an attachment to him. Though he doesn't know it yet, this baby is named Kaiser de Emperana Beelzebub IV, or "Baby Beel" for short—the son of the Demon Lord!

As if finding the future Lord of the Underworld isn't enough, Oga is also confronted by Hildegard, Beel's demon maid who insists he take responsibility as Beel's guardian. Together they attempt to raise Baby Beel—although surrounded by juvenile delinquents and demonic powers, the two of them may be in for more of a challenge than they can imagine.
