Nao&#039;s older brother. 1st year high school student. He&#039;s interested in his sister but just can&#039;t seem to get his hand to her.  When he was younger, he was really perverted and used his childhood friend Tsuchiura Iroha play doctor with him, as he wanted to see a girl naked.  However, she made him promise that if he let him do anything, make her his lover.

Junior High student Nao's brother complex is so strong, it's almost at the point of incest. She's determined to make her brother, High School student Shuusuke, see her as a woman. So determined, that she goes as far as going into his room to throw away all his non-incest related porn. But as she's looking for his porno stash, she finds a photo album... and she's not in any of his childhood pictures. What is going on?

High School junior Takanashi Nao has a problem: she has a crush on her dreamy older brother, Shuusuke. Fortunately, when Nao discovers that she was adopted as a child and they&rsquo;re not related by blood, it seems like the coast is clear&mdash;but Shuusuke just doesn&rsquo;t see it that way. 
To make matters worse, Nao finds herself in direct competition against Shuusuke&rsquo;s hot childhood friend, Iroha, not to mention class president Mayuka. As all three girls vie for Shuusuke&rsquo;s attention, Nao soon learns that all is fair in love and war!
