By entering Cello, gods mix together, become one, lose their ego, and find peace. That is his origin and the reason for his high specs. The reason he blended into human society is that the first King scouted him, inviting him to help create the nobility system, and he went along with it on a whim. When he was younger, he lacked humanity and emotion, so he tried many things to understand them, resulting in many byproducts. His younger self spoke bluntly without honorifics and was foul-mouthed. His expression was nearly blank, his atmosphere flat, and he used the first person "Ore" (rough/masculine). Having lived for 4000 years, he was present when the nobility system was established. In other words, he is a veteran aristocrat.
