Lux, a former prince of an empire named Arcadia that was overthrown via a rebellion five years earlier, accidentally trespasses in a female dormitory's bathing area, sees the kingdom's new princess Lisesharte naked, incurring her wrath. Lisesharte then challenges Lux to a Drag-Ride duel. Drag-Rides are ancient armored mechanical weapons that have been excavated from ruins all around the world. Lux used to be called the strongest Drag-Knight, but now he's known as the "undefeated weakest" Drag-Kn...
Saijaku Muhai no Bahamut is the fourth project created to commemorate the 10th anniversary of the establishment of the GA Bunko imprint, the production company responsible for launching the original source material.
A pacifist prince forced into a harem‑filled mech academy must fight without ever striking a blow.
When the deposed prince of Arcadia, Lux, stumbles into the girls’ bath at the royal academy, he witnesses Princess Lisesharte in the nude and instantly earns her ire. The affront sparks a Drag‑Ride duel—a clash of ancient, hulking mechs that once defined the empire’s might. Though Lux once bore the title of the strongest Drag‑Knight, his current reputation is a paradox: the "undefeated weakest" because he refuses to strike a single blow. The battle becomes a test of pride, strategy, and his stubborn pacifism. After the heated showdown, Lisesharte forces Lux to enroll in the all‑female Drag‑Knight academy, a prestigious institution where future royals are forged into mech‑wielding warriors. Surrounded by a colorful harem of talented classmates and overseen by eccentric instructors, Lux must navigate school life, budding romances, and the ever‑present threat of rival factions seeking the lost relics of the ancient Drag‑Rides. While his combat instincts are legendary, his reluctance to kill turns every mission into a comedic dance of clever tactics and unintended mishaps. The series blends high‑octane mech action with slapstick ecchi moments, all set against a backdrop of political intrigue and a lingering mystery about the empire’s downfall.
A battle-harem series where a former prince hides his identity at an all-girls mecha academy. Expect regular fanservice (bath scenes, torn clothing, compromising positions) alongside robot action and light romance; the tone stays playful rather than explicit.
