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.

Fuuta-kun has never owned a cat before, but his younger sister, Pii-chan, moves into his house with the round gray cat Kyuruga. Inexperienced with cats, Fuuta-kun has no idea what to expect, and each night after he returns home is marked by odd and endearing surprises from his new pet.

Four months after the battle at Nagoya Castle, Yu-yu and friends received an invitation to a tournament. That "Deluxe" tournament aims to determine the strongest fighter, bringing together both "Front Fighters" who are active in official tournaments, and hidden powerhouse "Counter Fighters" like "Blackout" that compete against each other for flags. The existing characters from overDress will be competing with new characters from will+Dress such as Raika, Michiru, and Urara, to become the strongest of them all!

In the magical academic city of Ashram, girls known as Pentagrams study general education, magic, and etiquette to become proper ladies. Hidden from the rest of the world, the school is like a secret garden that is home to blossoming flowers. However, bugs sensitive to magic may target and trample them; as one of their tasks, the girls must exterminate these insects. The smileless Pentagram Arsnotoria lives in the fifth dorm house alongside her adored roommates: the cheerful Mell, the self-paced Little Alberta, the confident Picatrix, and the cool Abramelin. No matter what time of day, they hang out together as much as possible, and even throw tea parties in their secret room after completing their duties. The girls live in peace as they work toward their goal—but there may be more to Ashram and the Pentagrams beyond the calm life they have come to cherish.
