A mysterious switch appeared one day. Upon pressing it, they were sent to a different alternative world!! There are also characters from other alternative worlds gathered together...!?

Atsushi Nakajima was kicked out of his orphanage, and now he has no place to go and no food. While he is standing by a river, on the brink of starvation, he rescues a man whimsically attempting suicide. That man is Osamu Dazai, and he and his partner Kunikida are members of a very special detective agency. They have supernatural powers and deal with cases that are too dangerous for the police or the military. They're tracking down a tiger that has appeared in the area recently, around the time Atsushi came to the area. The tiger seems to have a connection to Atsushi, and by the time the case is solved, it is clear that Atsushi's future will involve much more of Dazai and the rest of the detectives!

Awaiting new club leader Kumiko is the Ensemble Contest, and the school's preliminary competition to determine the representative team to participate. Kumiko tries her best to make it to the preliminaries without incident, but the concert band club is so large that there seems to be no end to the problems. And as club leader, she finds herself busy consulting on all sorts of matters. While the other members are deciding on their teams, Kumiko herself hasn't even decided which she will join...

Kumiko is now a second year and one of the senior players of the euphonium section. With new underclassmen joining the concert band, Kumiko will have to learn new things in order to deal with awkward and difficult underclassmen. She and third-year trumpeter Tomoe Kabe have been chosen to lead the new underclassmen members. Among the new members to Kumiko's bass section are euphonist Kanade Hisaishi, whose appearances are deceiving; tuba player Mirei Suzuki, who cannot adapt to her new environment; tuba player Satsuki Suzuki, who wants to get along with Mirei; and double bassist Motomu Tsukinaga, who cannot talk about himself. Between the Sunrise Festival, chair placement auditions, and the competition, a number of problems quickly begin to arise.

Tsukasa’s position is in the terminal service department where the main job is to recover Giftias that are close to their expiration, a graveyard department in every sense. To make matters worse, Tsukasa is ordered to work with Isla, a female Giftia who is never given any responsibility other than serving tea to co-workers.

Young Tatsumi travels to the capital of the Empire in order to earn money for his starving people and encounters a world of unimaginable depravity, dominated by the ruthless Prime Minister who controls the child Emperor. Tatsumi is recruited by Night Raid, a group of assassins dedicated to eliminating corruption by mercilessly killing officials and privileged nobles.

Humans have created many stories. Joy, sadness, anger, deep emotion. Stories shake our emotions, and fascinate us. However, these are only the thoughts of bystanders.
