In Isekai no Seikishi Monogatari, Kenshi Masaki is dragged away from his ordinary life and brought to the world of Geminar by a mysterious group, only to be trapped in a desperate bargain with no easy way back. His path home begins with an assassination attempt against the newly crowned empress of the Shtrayu Empire, Lashara Aasu XXVIII, carried out with a giant robot known as a Sacred Mechanoid. When the attack fails and Lashara learns that Kenshi is male, a rare presence on Geminar, she decides not to discard him and instead makes him her attendant.
Bound to Lashara’s side, Kenshi travels with her to the Holy Land, an academy where Sacred Mechanoid pilots are trained and where rivalries, politics, and hidden agendas shape everyday life. As he struggles to understand the customs of this unfamiliar world, his unusual abilities draw the attention of allies and enemies alike. What begins as a reluctant survival arrangement soon becomes a deeper entanglement, as Kenshi and Lashara are pulled into the growing tensions around the academy. An unseen threat gathers in the shadows, and the possibility of war begins to spread across Geminar, turning their uneasy alliance into something far more dangerous.
