NTR Kishi

Coleus trains as a knight apprentice at a remote soldiers’ academy. His new instructor is Artel, the childhood friend who left years earlier for the royal capital and rose to knight-commander before returning home. She is stronger, more beautiful, and still the girl who once pulled him out of trouble with a blade. Their reunion is warm. Both still carry unspoken feelings.

Artel’s appointment immediately inflames Lock, a fellow instructor whose status she has displaced. He does not challenge her with steel. He uses magic that seizes the mind, strips resistance, and leaves the body obedient while consciousness fades. In front of Coleus, Lock violates the woman Coleus has loved since childhood: her trained knight’s body is treated as a prize, her virginity taken, her large breasts used as proof that rank and pride mean nothing under a spell.

The assault does not end with a single night. Lock’s methods escalate. While Artel is only half-aware, the same physique she forged as a female knight is re-educated toward pleasure and submission. Coleus can only watch the person he waited for become someone else’s instrument. The official logline is exact: the joy of reunion is the beginning of the nightmare, and a proud knight’s soul is overwritten—NTR—by a coward’s trap. Studio Majin petit, with character design and storyboards by QEGGY and script by Tokku03, frames the original game’s jealous, bitter tone as a short, dense adult OVA rather than a light fantasy romance.
