Urara no Pantsu wa Tenchou wo Komaraseru  

The employee who works part-time at the restaurant has a greater interest in cheating than performing their job duties. The new manager of the restaurant with poor sales wants to improve their performance and receive a promotion but faces challenges from Urara, the kitchen manager who plays pranks on them, as well as Ai, the big-boobed girl who plans to take over as manager, and Ayano, the serious but quirky high school student who leaves work early.
