Kenshi, the half‑brother of intergalactic hero Tenchi Masaki, is summoned to the mysterious world of Geminar. With the only way to return to Earth being a daring attempt to pilot a bio‑mechanical weapon at an assassination plot, his plan goes awry and he is captured. As he realizes that the very beings who transported him have deceived him, he finds unexpected refuge in Princess Lashara, who welcomes him and invites him to join her followers. Now entangled in a political maelstrom and pursued by Geminar’s female population, Kenshi must find a way home while a civil war erupts all around him.
