Chosen by the Church's god, Origin, a young country girl named Flum Apricot is enlisted in the hero's party and expected to fight demons. However, her one innate skill, Reversal, has no practical use, and the party's sage, Jean Inteige, treats her as a burden, eventually selling her off to a slave dealer. In the slave dealer's dark dungeon, all hope seems lost. But in a moment of desperation, Flum discovers that her skill actually turns the negative energy of cursed weapons into power, which helps her slay the slave owner and escape with another captured girl, Milkit. Now equipped with the means to fight and survive, Flum embraces the career of an adventurer and aims to lead a happy life with Milkit, away from the grim machinations of the Church.

Fourth season of Osomatsu-san.

Rika Furude and her group of friends live in the small mountain village of Hinamizawa; in June 1983, they welcome transfer student Keiichi Maebara into their ranks, making him the only boy in their group. After school, they have fun playing games and spending each day living their lives to the fullest. Despite this seemingly normal routine, Keiichi begins noticing strange behavior from his friends, who seem to be hiding the town's dark secrets from him. Elsewhere, a certain person watches these increasingly unsettling events unfold and remembers all the times that this, and other similar stories, have played out. Using that knowledge, this person decides to fix these broken worlds. However, when certain variables change, the individual is faced with a horrifying realization: they have no idea what to expect or how to stop the impending tragedy.

It is 1983, and Hinamizawa is under quarantine. A mysterious and deadly virus has been discovered within the small village, and its residents—such as teenager Keiichi Maebara and his friends Mion Sonozaki and Rena Ryuuguu—are left confused and frightened by the situation. As the villagers begin to search for a way to stop the affliction from spreading, some make drastic plans, which leaves Keiichi and his friends looking for a way to escape the village. But when tensions reach an all-time high, some of his group may not make it out unscathed as they fight for their lives against enemies both seen and unseen.
