Akira Uehara

When Uehara comes to Momoi039s house to give her the homework she missed he finds her attached to the wall as her madscientist grandfather is about to test his machine on her. He tries to save her but unfortunately the girl he loves turns on him and convinces her grandfather to use Uehara as the test subject instead. In an attempt to get Uehara the grandfather accidentally presses a lever which causes Uehara and Momoi to switch bodies. Because he is in her body Momoi often threatens Uehara not to do anything to her quotpurequot body or else she will go out in public in his body with nothing but socks on. Uehara fearful obliges though there are some cases in which his curiosity gets the best of him usually resulting in a violent nosebleed. As a girl Uehara in Momoi039s body is more wellliked by her peers to the extent that some males develop a crush or feelings toward him/her including Uehara039s best friend Senbongi and Shiina039s older brother. He is very adamant about returning to his normal body though there are many factors that prevent him from doing so. i.e. Momoi Momoi039s grandfather being lazy Senbongi etc. Source: Wikipedia
