Sohara is Tomoki's childhood friend who lives across the road from him, often going to his house in the morning to wake him up. As a child she was constantly ill and thus had few friends. She is continually jealous of Tomoki's relationships with the various Angeloids and generally acts on this jealousy by "Karate-Chopping" Tomoki; however, she also does that whenever he's being perverted in her presence, as well as in various other situation when his behaviour goes 'out of hand'. She is also quite obviously in love with Tomoki and her breasts always seem to be getting bigger; they are the biggest in the series(In one of the chapters, Tomoki commented that he knew all her measurements down to the last centimeter).
