Seirei Tsukai no Blade Dance

Kazehaya Kamito is summoned to Areishia Spirit Academy, a school for noblewomen who form contracts with spirits. While traveling there, he accidentally sees Clair Rouge, a student bonded to a spirit named Scarlet, in a compromising situation. Clair is interested in securing a stronger spirit and agrees to guide Kamito to the academy. Along the way, she attempts to bind the powerful spirit he was summoned for, but Kamito ends up taking it instead. This reveals that he is a rare male spirit contractor, a phenomenon unheard of. Clair now believes the spirit should be hers and insists that Kamito assist her in claiming it.
