Wagnaria!! 

Set in a family restaurant in Hokkaido, the northern prefecture of Japan, 16-year-old high school student Sōta Takanashi works part-time along with his strange co-workers: Popura Taneshima, a high school girl who-despite being a year older than Sōta-is easily mistaken for a elementary/middle schooler, and Kyoko Shirafuji, the 28-year-old store manager who does not bother to do any work at all.

Wagnaria!! Season 2

Life goes on at the Wagnaria family restaurant as its peculiar employees try to provide a good service despite their individual eccentricities.
