She loves the sea more than anyone and has extensive knowledge of the ocean, but since childhood, she has been gaslit by her mother saying, "You must be a good child, a chief everyone can rely on." Currently, she is trying to focus on her duties as the successor. However, she still lingers for the sea, taking long walks on the beach at dawn. On the surface, she is bright, kind, and has leadership qualities, but the inner self she shows only to close friends is dark and cynical.

Over 2,000 years old (physical age 17), Female, fluffy lime-green hair and purple eyes, 156cm. A siren who roams the sea, enchanting sailors with her beautiful singing voice to sink their ships.

Over 2,000 years old (physical age 18), Female, brown bob cut and brown eyes, 158cm. In the past, she was "Ena," the Goddess of Abundance and Earth; now, she is "Shinonome," a lava demon who kills everything that comes near. She turned dark after the Weirdo Duo stole her heart. She has a sharp and frequently grumbling personality, but also has a tsundere side (this isn't because of the corruption, she was always like that). She is slightly softer toward those younger than her (like Emu). Ena's heart is in the form of a glowing green pebble. Being a god-like being, not having a heart doesn't affect her much physically, but she says it makes her feel extremely unpleasant. If the heart is returned, she goes back to being the Goddess of Abundance. As a lava demon, she cannot enter the sea. She lives on a volcanic island where no living things exist besides Ena. Because Ena killed them all.
