Welcome To Pia Carrot 2

Yususke (from the first Pia Carrot series) returns as the manager with a whole new cast. So the new male lead is Koji.

Despite being late after an "accident," Koji manages to get the job as the Carrots waiter because hes very persistant. Included within the set are Azusa (the female lead who hates Koji for his perversion), Ryoko (the manager whos sweet on Koji by working him very hard), Aoi (the token alcoholic), Jun (the secret-hiding waitor), and Mina (Azusas cute little sister). Pia Carrot 2 is served up as a romantic comedy, with a side of hentai.
