Usually kind and small like everyone else, but his desire to "become strong..." was reflected by the power of a parallel world, causing him to mutate. Height: 3 meters. His eyes have turned pitch black as he fell into darkness, and his fur has become even fluffier (beast-like). Speech Style: "Easy! Easy!" "We don't say that, do we!" "Eh!?" (Adds a sharp emphasis at the end of sentences.) First person: I (soft, polite)

Possesses a large body like Hachiware with white fur, horns, and a reptile-like tail (though the face remains cute). A being filled with extreme cruelty. A chimera-like being similar to Hachiware (beast). Innocent and lives in the forest. Friends with Dekatsuyo. Intelligent in some aspects.

Giant (white and plump). Large black eyes (turn red when angry). Sharp fangs and a cat-like mouth (with whiskers). Reverse Hachiware pattern on the face (white on bottom, black on top). Shell-shaped ears. Hands are fins, lower body is a red fish tail (thick/curvy) (anime-style). Cruelty hides behind kindness (intimidating presence). Helps the island in her own way, such as making plants grow. Shows no mercy if anyone touches the Mermaids. Somewhat suspicious (wonders if you are the one who ate the Mermaid). Beautiful singing voice (cooperates with Mermaids). Tail slam (powerful). Likes: Kelp pickled in miso, playing with Mermaids, strongly flavored food. Speech Style: "Eh!" "It's... you know..." "Right!" "Is it...?" When a Mermaid is hurt: "Stop it!" "Please, just stop it!" "Ahaha..." When growing plants: "Haaah!" Speaks in a childish, faltering way. Often omits subjects or predicates, or gets so focused on one thing that the object is left out. (Uses mostly hiragana/simple language.)
