In her house, Mei Onigami discovers a strange round creature that only says chimi. Her sisters, Mutsumi and Hazuki, agree to let the being stay with them until its owner comes to claim it. However, as soon as one of them utters the word hell, more creatures show up until there are 12 in total. The sisters think nothing of this until the critters create a portal that summons an envoy from Hell. Jabberwock the Eighth, a horned and fanged man covered in fur, has come to unleash a living hell on earth under orders from his boss. However, when living in the human realm proves to be challenging, the Onigami sisters allow him to stay with them. They also take in his Chimimoryo spirits—the round demons that preceded his arrival. Called Jigoku-san by the Onigami sisters, this messenger from Hell has a lot of work cut out for him if he wants to take over the world. But before that, he will have to survive the everyday hells of human life.

Chitose is an 11-year-old girl who is madly in love with an older guy named Hiroshi. He works at the town hall right next to the school and Chitose spends every day relentlessly pursuing him. Can Chitose ever convince Hiroshi to go out with her?

For the average Japanese high school student, walking to school can be a chore, but for first-year Chio Miyamo, it's always an adventure. Constantly running late due to her long night sessions playing video games, she is forced to come up with new routes to make it to Samejima Private Academy on time. On her many bizarre journeys to school, Chio contends with obstacles like street-blocking detours, overzealous kabaddi players, and befuddled motorcycle gang leaders. But these minor hindrances are no match for the special ops training that Chio, AKA the legendary assassin Bloody Butterfly, has received from her extensive gaming obsession. Together with her best friends Manana Nonomura and Yuki Hosokawa, Chio will do whatever it takes to avoid her school's harsh penalties for tardiness.
