Unnamed idol duo


A duo comprised of two female cuttlefish was previously popular among teenagers and still composes music for the industry in the present day. One of them sang loudly while the other had a soft, whispering voice. Their album artwork can be found floating in the background in Stick 'n' Move Station with the artists removed, although one of their forearms remains. When translated, the text on the top-right corner reads "COIKARS" in Halfmoon script. This is a play on コウイカ kouika, the Japanese term for cuttlefish (specifically the golden cuttlefish). The text in the bottom-right corner, when translated from one of the Inkling alphabets, reads "pop pop pop", "hakkisyon!", and "Bye bye". Despite being cuttlefish, they resemble Inkling idols such as the Squid Sisters, Pearl, and Frye.

Unnamed folk rock band


In the 1990s, an album by a folk rock band gained enormous popularity after one of its songs was featured as the theme song of a famous drama, to the point that it stayed on the charts for two years even after the end of the drama. The band broke up at some point despite their good reception, but the members are still musically active.
