Udauda Yatteru Hima wa Nee!  

ウダウダやってるヒマはねェ!

Shimada Aki and Akaki Naomi have been friends since childhood. While Shimada is playful and only takes things seriously when they're fun or profitable, Akaki is more serious, caring, and straightforward. Despite their differences, both are skilled at fighting (bullying). This manga follows the misadventures of two carefree high school buddies whose accidental fights make them famous among Japan's dangerous and influential gangsters.
