As another school year begins drawing to a close, the third-year high school students move steadily toward the next milestone of their lives: graduation. Among them are Mio Natsume, a girl burdened with lingering feelings; Hazuki Morikawa, a member of the concert band but distant from the others; and Haruto Souma, an athlete obsessed with baseball. Meanwhile, second-year student Ena Komiya seeks to revive the photography club to its former glory, refusing to let the organization be disbanded. Though this group lacks a strong connection with one another, their lives suddenly cross paths with the arrival of a third-year transfer student. While a transfer so close to graduation is unusual for most, it is business as usual for Eita Izumi. Due to his father's work, he has never been able to stay in one place for very long. But as luck would have it, their most recent relocation has returned Eita to his hometown for his final semester of high school. For better or worse, it also sparks the rekindling of old relationships left behind in the past. With graduation already causing its own share of anxieties, Eita's sudden arrival brings these students' carefree days to an abrupt end. Long-forgotten memories, deeply buried emotions, and inspiring new passions—everything is brought to light in their bittersweet final semester. [Written by MAL Rewrite]

Catarina Claes, the young daughter of a noble family, one day bumps her head and regains memories of her past life as an otaku. It is then that she realizes she has been reborn into the world of the otome game Fortune Lover, reincarnated as the game's villainess who, regardless of what route the player took in the original game, is doomed to be either exiled or killed. In order to avoid these routes that lead to doom, Catarina begins taking countermeasures. This, however, ends up having unexpected consequences on her relations with the other characters of the game's world.

The year is 2071. Humanity has been pushed to the brink of extinction following the emergence of man-eating monsters called "Aragami" that boast an immunity to conventional weaponry. They ravaged the land, consuming almost everything in their path and leaving nothing in their wake. To combat them, an organization named Fenrir was formed as a last-ditch effort to save humanity through the use of "God Eaters"—special humans infused with Oracle cells, allowing them to wield the God Arc, the only known weapon capable of killing an Aragami. One such God Eater is Lenka Utsugi, a New-Type whose God Arc takes the form of both blade and gun. Now, as one of Fenrir's greatest weapons, Lenka must master his God Arc if he is to fulfill his desire of wiping out the Aragami once and for all. The monsters continue to be born en masse while the remnants of humanity struggle to survive the night. Only God Eaters stand between the Aragami and complete and total annihilation of the human race. [Written by MAL Rewrite]
