In the world of Beastkin sports, no one does it better than the renowned elite school of Tsukumo Private Academy. Together in a lavish clubhouse, the rabbit boy Yuuto lives with his two stunning upperclassmen as their fitness trainer. Airi—the lion beastkin and pride of her basketball team—and Itsuki— the wolf beastkin and ace track star—look to him for guidance, but as their sweat stings the senses and they walk around unashamed, it's hard to keep his rabbit instincts from going overboard! Just like the heat of battle, Airi and Itsuki also need to relieve the heat between the sheets… but if Yuuto doesn't watch out, they're going to gobble this little rabbit up!
