Set in a different series of events, this story does not follow the previous Appleseed movie canon (despite being directed by the same director of the previous movies); it is an alternate story to their beginnings. Briareos is already a cyborg and did not become separated from Deunan to be later reunited in Olympus to join ESWAT.

Appleseed Alpha depicts the early days of Deunan Knute and Briareos in the 22nd century, as they embark on a journey throughout dystopic ruins of New York in search of the city of Olympus. They are hired by Two Horns, the warlord of the ruined city, to eliminate bipedal combat machines. During the fight, they encounter Iris and Olson, both on a mission. Deunan and Briareos befriend them and decide to join their mission.

Iris is tasked with preventing the malevolent cyborg Talos from capturing a secret weapon humans were building. Talos uses Iris to activate the gigantic war machine.

The long-awaited new work will be screened in theaters as a medium-length animation in the summer of 2023! Along with the summer brass band competition, the ensemble contest, commonly known as "Ancon," is a place where exciting performances are held. The performance of several people in one group has a charm different from that of a competition. In order to participate in the Kyoto prefectural tournament of Ancon, a representative team is selected in the school's preliminary round. However, with over 50 members, the Kitauji High School brass band is facing a variety of problems! Will Kumiko, the newly appointed head of the club, be able to make it through the preliminary rounds? The days of struggle begin.

In most ordinary high schools, many stories and rumors float around—some scandalous, some happy and some...more macabre. One such example is of monsters lurking in an abandoned mansion outside of town. Such tales, however, prove too tempting to resist for Hiroshi and his friends Mika, Takeshi, and Takurou. They decide to brave the rumored dangers in order to investigate the manor and complete a test of courage. Each of them approaches the mansion with an overwhelming sense of dread. And when they enter, they come upon a blue monster named Ao Oni who attacks them. As Hiroshi and his friends try to solve the various puzzles in the mansion and escape their new blue nemesis, they find themselves meeting several horrible endings as they fail miserably.
