Plus-Sized Elf

Naoe and Erufuda visit a sauna that is rumored to be haunted by demons. There they find the ogre Oga! Oga has been spending his time in the sauna worried about his belly getting bigger from drinking too much. When Naoe and Erufuda visit the fish shop, they once again encounter people from another world. Yoneji, a clerk at the fish shop, is a mellow mermaid, but she is worried about her saggy upper arms because she doesn't have a chance to swim in her mermaid form. Naoe offers to help her get rid of the sagging upper arms. (Source: Official Site)
