So, I Can't Play H, Vol. 3

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 pin-up 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"?!
