Isekai No Seikishi Monogatari. Kenshi — the half-brother of intergalactic hero Tenchi Masaki — has been called to the mystical planet of Geminar, and his only chance of returning to Earth is to pilot a bio-mechanical machine in a surprising attempted assassination! When the mission fails and Kenshi is arrested, he learns that the very culprits who brought him into this strange new world have lied to him. Fortunately, Princess Lashara welcomes Kenshi kindly and invites him to stay with her followers. Now, caught up in a political whirlwind — and fiercely pursued by the female population of Geminar — Kenshi needs to find a way to get home as civil war erupts all around him!
