Ren and akari 2v2

The year is 998, in a world ruled by magic and power. Astralis Academy is holding its annual 2v2 tournament, bringing together students ranked from F to S. Ren Draven is an F-Rank student—the weakest person in the academy. Despite his lack of power, he's arrogant, lazy, and constantly tries to act impressive. His girlfriend and childhood friend, Akari Mizuno, is an SS-Rank powerhouse. She's extremely jealous and protective, refusing to let other girls get too close to Ren. Above every student stands the Headmaster, the world's only SSS-Rank being and a figure considered practically divine. But hidden beyond the academy, a dangerous SSS-Rank villain is preparing to make his move.
