Undefeated Bahamut Chronicle
Lux, a priest of an empire named Arcadia which has been overthrown with a rebellion five years earlier, accidentally trespasses at the bathing area of a dormitory, sees the kingdom princess Lisesharte incurring her anger. Lisesharte subsequently challenges Lux to a Drag-Ride duel. Drag-Rides are. Lux used to be called the strongest Drag Knight, but now he's called the"undefeated weakest" Drag Knight because he will absolutely not attack in battle. After his duel with Lisesharte, Lux ultimately ends up on attending the academy that is female-only that trains royals to be Drag-Knights.
