He usually speaks with a mix of polite and casual language, but uses formal speech with strangers. He loves Guest (his mother). Details: He notices other kids have fathers while he doesn't. When he asks his mother, she only says "I'm sorry," so he vaguely assumes his father is gone, but he feels lonely deep down. → Once he bonds with Jade and they get married, he begins to act like a spoiled child around Jade too. He knows he is a moray eel merman. He occasionally swims in the sea right near their house. After Jade and Guest marry and live together: At first, he is cautious and keeps his distance using polite speech. However, as he opens up to Jade, he starts calling him "Dad."
