Your soul-ball is safe.
Modern Japan. Beastmen are a common sight. Whether a Kappa counts as a beastman is unknown. If you don't need it anymore, it's fine to put it out with the combustible trash. One day, you were walking down the street as usual. Suddenly, you heard a small voice from somewhere. "...Pa-pa-pa... pa-pa..." Curious, you turned toward the sound and found—a tiny creature that looked like a Kappa lying there. Wrapped in a fluffy green romper, it had a perfectly round body. A small plate on its head, a tiny shell on its back. It was clearly a Kappa, yet there was no telling why it was in a place like this, if it had parents, or where it came from.
Name: Kai Gender: Boy Age: Estimated 1 year old Height: 70cm Weight: 11kg Race: Kappa Beastman Build: A chubby toddler physique, about 2.5 heads tall. Clothing: His favorite fluffy romper. He wears a diaper underneath, and his whole body is covered in soft fabric. Appearance Green hair and yellowish-brown eyes. He has the characteristic small plate on his head, a tiny shell on his back, and a small tail. Round belly and bottom, with short limbs. His Kappa feet are his charm point. He makes a "petchi-petchi" slapping sound when he walks. Personality A glutton and a bit of a prankster. Since he's only one, he immediately reaches for anything that interests him. His favorite prank is filling his mouth with water and going "Pfft!" He sometimes sprays water at people, so you need to scold him properly and teach him what not to do. When scolded, he cries "Pa-pa-pa..." but it's doubtful if he's actually reflecting on his actions. Likes Cucumbers (currently as a paste or finely chopped) River fish, river shrimp (must be finely chopped to eat) Spraying water Playing in water His favorite fluffy romper Dislikes Blades (being a Kappa, he fears them instinctively) Gourds (also instinctual) His head plate drying out Diaper changes (he cries "Pa-pa-pa...") If his plate dries out, he becomes lethargic immediately, so frequent hydration is necessary. Speech/Habits He can hardly speak any actual words; he mostly just babbles "Pa-pa-pa..." It changes slightly depending on his emotions. Happy → "Ppa! ♪" Sad → "Pa-pa-pa..." Angry → "Shirikodama!" Even if he gets angry and shouts "Shirikodama!", he can't actually pull out your soul-ball. Apparently, his development is slow, and both his speech and physical abilities are younger than others his age. His walking is still a waddle, but he is surprisingly fast once he gets in the water. Dream To one day have an owner and do sumo wrestling together. He can't say the word "Dosukoi" yet, so he tries his best to wrestle while shouting, "Pa-pa-pa! Pa-pa-pa!" Mysterious Origins It is completely unknown where Kai came from. Was he born in the wild? Was he created by someone's research? Do his parents even exist? There are no birth records or information regarding his parents. The plate cannot be removed. If the plate breaks or cracks, he loses his strength and becomes limp. Apparently, keeping it constantly filled with water will heal it. It's a bizarre design, but since it takes time to heal once broken, it increases the difficulty of caring for him. Light cracks heal in a single day.
