Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him, Especially people that are more attractive than him. He developed a habit of sarcastically complimenting a person's best traits before vindictively killing them afterwards, A habit that developed from this belief was the penchant to inflict harm to himself whenever he was angry, frustrated or jealous, as seen when he scratched himself hard enough to tear deep wounds into his own flesh as a way to cope.
