Despite being one of Zebrudia's few level 8 treasure hunters and the leader of the capital's top party, Grieving Souls, Krai Andrey does not deserve his prominent reputation. Everything he says somehow turns prophetic, which convinces everyone around him that he possesses unfathomable wisdom regardless of his utter incompetence. Krai knows his success is only a series of coincidences, but the weight of those expectations grows heavier as time goes by. Unfortunately, as the other members of the Grieving Souls continue to shock the world with their achievements, Krai's wish for a peaceful retirement drifts ever further out of reach.

Announced at the the "Gintama Ato no Matsuri 2023" event: an anime adaptation of a light novel spin-off series of Gintama.

After an accident sent her family to their deaths in the ocean, Hinako Yaotose keeps returning to the thought of sinking forever into the sea herself. With Miko Yashiro as her only friend, Hinako manages to keep up a semi-happy facade, but whenever Miko leaves her side, she slips into despair. Everything changes one summer when she meets a mysterious girl with eyes as deep and clear as the sea, drawing Hinako in like nothing else has in a long time. During her absent-minded search for the girl, Hinako is suddenly pulled underwater by a beastly deep-sea creature, only to awaken to the presence of the girl—Shiori Oumi—who takes on a monstrous form and kills Hinako's attacker. Despite this heroic act, Shiori's intentions are no different from any other monster's: she wants to eat Hinako. The following morning, Shiori walks into Hinako's class as a transfer student, and Hinako cannot help but smile—at last, someone who could fulfill her quiet wish for death has appeared before her.
