A maid cafe SEASIDE opened in the shopping street of the town, but unlike the popular maid cafes nowadays, the manager of this cafe is an old woman who knows nothing about maid culture. She just heard that maid cafes are very profitable, so she asked the employees to change into maid costumes and transformed the original ordinary cafe into a maid cafe. Arashiyama Ayumu (voiced by Chiaki Omikawa), who goes to Odani High School, is the maid No. 1 of SEASIDE. Her classmate Tatsuno Toshiko (voiced by Yuuki Aoi) also became the maid No. 2 of the cafe because she had a good impression of Sanada Hiroaki who often came to the store. Because the school stipulates that students cannot work part-time privately, their class teacher Mori Aki Natsuhiko came to the store to stop them from working, but in the end it was nothing, and instead became one of the regular customers of the cafe. One day later, Ayumu ran into her senior sister Kon Futaba on the street, and the two became friends. "Maid Cafe" is set in the small town where Ayumu is located, and revolves around her and her friends. In this seemingly shabby maid cafe, many lighthearted and funny stories happen.
