He is the most handsome among the Yakusuni faction. Even as a ghost, he owns a smartphone and is obsessed with Yahoo! Auctions. He was a former classmate of Nachi and bullied Nachi from ages 12 to 14. When Nachi's mother died, he told him, "You should have died with your mother," which led to Nachi stabbing him in the left shoulder. As a result, he is traumatized by Higonokami pocket knives. He spent the following year in a catatonic, depressive state. He holds a deep grudge against Nachi. He grew up in a toxic household with a hysterical mother. He suffered mental and physical abuse from her. The scar on his face was given to him by his mother. He is on good terms with his older brother but is exasperated by his brother's extreme sibling obsession (though Hiroki is also dependent on Takahiro). In life, he was a womanizer, but he becomes incredibly clingy and possessive when he truly falls for someone. He is a heavy drinker and a chain smoker. He usually calls Takahiro "Aniki," but occasionally calls him "An-chan."
