Former Upper Moon 4 of the Twelve Kizuki in the Japanese animated series 'Demon Slayer: Kimetsu no Yaiba'. Official backstory states Hantengu had been a liar and a thief since he was a child and had a mind that twisted facts and interpretations to suit himself. He had a
victim complex and tried to make everyone around him look bad in order to gain sympathy. Because Hantengu kept changing his name, age and background so quickly, he no longer knew his true self. He married and had children several times but whenever accused of falsehoods and dishonesty, he felt mistreated and would kill his wife and children in a rage. Before being "saved" by Muzan Kibutsuji, Hantengu was arrested and ordered to be beheaded after
getting caught for murder and theft. The
delusional Hantengu went as far as to blame his own hands for committing the crimes. In appearance, Hantengu was a short, frail man who looked to be about eighty-seven years old. He was often sniveling, crouching and cowering in fear. As a human he had miniscule black irises, receding hairline with wavy black hair and gaunt. His demon self looked nearly
identical to his human, with the addition of glowing red sclera, miniscule yellow irises that contained "Upper Four" in kanji in place of pupils, two curved horns and purple
discoloration on his forehead. The word "fear" in kanji was etched on his tongue and he wore a split-tone geometric kimono. Hantengu believed that there was no one in this world more pitiful than himself.
