The wraparound jacket on the 21st volume of Natsumi Aida's Switch Girl!! comedy manga revealed on Friday that the manga is entering its final arc with the volume. The series follows a seemingly ultra-cool and stylish girl named Nika Tamiya, but the fashionable persona is all an act that she "switches" on when she is out. At home, she "switches" off and reveals her true slovenly self that almost no one at her high school knows. One day, a transfer student named Arata Kamiyama moves into her apartment complex and discovers both sides of Nika.

The series has inspired two live-action television drama adaptations. The first season premiered in December 2011, and the second season premiered last month. Seventeen magazine model Mariya Nishiuchi stars in the adaptations as Nika, and Renn Kiriyama (2011 Hana-Kimi's Nanba) plays Arata.

Aida launched the manga in Shueisha's Margaret magazine in 2006.
