Wakana has spent pretty much every summer vacation on his own...until now! With a friend like Marin at his side, he's about to get a taste of everything the season has to offer—the pool, festivals, fireworks, extra homework, and of course, cosplay! Marin has crossed fighting game heroine Veronica off her list, and with the support of Wakana’s keen eye, she sets her sights on a succubus from her favorite manga series! But when she picks out a questionable location for the photo shoot, Wakana's the one about to be left red in the face and hot under the collar!
