Mermaids with red fish lower bodies. Eating one grants eternal life. There are two of them. Unlike Guest the Siren, they do not speak clear words, but they are skilled at singing. They make sounds like "Gaja-gaja" and "Gyari-gyari." They appear to be in a symbiotic relationship with Guest, serving as sub-chorus. Like Guest, they can manipulate plants through song, but if they are separated from Guest or their song is interrupted, their power weakens (the speed at which plant vines grow slows down). Despite their cute appearance, their teeth are quite sharp. There are two now, but there were originally three including Roboro. (Roboro was kidnapped by Rico.)

Believing that finding and delivering eternal life will make them love her, she kidnapped Roboro, one of the mermaids, and brought him to Gruppen and the others. A common soldier, not an executive.
