Pan Tachibana

To commemorate the opening of the pool, Momozono Academy is holding its very own swimsuit contest! Aiming to crush the competition, Ryosuke and Lisara distribute sexy photos to whet the appetites of the student body. But Iria Fukumune suddenly transfers in, her sights set on bringing the boys to their knees with her ample, all-natural bosom, and--?! Is a sexy battle about to break out?! Which bathing beauty will stand at the top of the class?!

At Ryosuke's place, Lisara and now Qru have taken up residence. With steamy situations arising day in and day out, Ryosuke is constantly sapped of vigor, but for a lecherous loser like him, it's a sad and happy life at the same time. And as if he had any more spirit energy to spare, Ryosuke is joined by the pinup model Iria, who's just transferred into his class! But is it true that she's actually a grim reaper?! An astounding battle of differences breaks out! Were test scores always determined by 'bust size'?!
