Tenkuu Senki Shurato: Sousei e no Antou

A mysterious source of Soma draws Shurato and the other guardians back to the human world. For Shurato, the homecoming brings a devastating discovery: every trace of his and Gai's former lives has vanished, and even his family no longer remembers him. Gai's older sister Mina alone still remembers her brother, and a mysterious young man stands close to her.

As guardians begin disappearing, the investigation becomes a struggle to save their companions. Mina's longing for Gai and the stranger's hidden ambitions pull Shurato into a conflict reaching beyond the world he once called home. To protect his friends, he must uncover what lies behind these disappearances and the threat gathering around Gai.
