Kazuma is a student and a successor of traditional martial arts. But he, who doesn’t train hard, is sent to an isolated island where a god of martial arts is believed to live. Kazuma meets Tomoe, a god of martial arts, there and she tells him that she will give him a hard training. “But I’ll get your energy in return….” Like this, his erotic training begins….
With his summer plans effectively ruined, Kazuma searches for shelter and almost immediately runs into the big boss, the Inugami dog spirit herself! Kazuma, rather clumsily, explains his situation in a last-ditch effort to escape the wrath of the creature who not only understands his ‘human speak’ but shapeshifts into a fluffy-tailed maiden and the two come to a surprising agreement. In exchange for learning some secret doggy-style techniques from Tomoe to get his father off his case, Kazuma will provide her with his ‘youthful essence~’
