Switch Girl 1 (2011)

Based on a manga with the same name created by Aida Natsumi, 'Switch Girl!!' revolves around a high school student named Nika (Nishiuchi) who appears to be a stylish and fashionable girl at school, but that's really a fake persona that she uses when she's in public. At home, she “switches off” the facade and her returns to her true slovenly nature. Kiriyama Renn plays the good-looking transfer student Arata, who is Nika's love interest in the story.
