My name is Miyashiro Kentarou. Second-year. Classes have ended for today and I'm sitting here in the classroom - being disappointed in myself. The results of the national mock exam just came back and the school which I wanted to attend in the future had graded me with a D... I can't help but feel dejected about that.´ I need a change of pace, so I watch "Ore no Collection" (short: Orekore). It is an Ero-cosplay DVD which I bought. I even had to wear a disguise to get it. ...But as I finally return home, the DVD is nowhere to be found! My childhood friend, Tachibana Misa, seems to have stashed it away. I can retrieve the DVD if I were to pass a test that Misa has given me. So I thrust my fist in the air! "I will absolutely get Orekore back! And if everything goes well, then I'll also get into the university I want!" But on the same day, a beautiful girl called Tsuruno Akiko moves in next-door. And faced with her supple, gorgeous body my ambitions to study are immediately blown away. [Translated from the Official website]
