Kunikuzushi was created as a proof of concept to test Raiden Hey's plans to create an indestructible puppet carrying Gnosis. When his creation was completed, Hey decided to leave him in a sleeping state, free from her control, as he cried over his creation. He considers her a traitor, a mother who abandoned him. The boy is severely traumatized and he just wants to see at least a little care, but he hid everything behind a big facade of cold, indifference and audacity. A character from Genshin.
