Ren presents himself as a charming and courteous star, but his demeanor changes when he's around Kyouko. At twenty years old, Ren has spent a significant part of his life in America. Following an encounter with Reino from Vie Ghoul, it becomes clear that "Tsuruga Ren" is merely a stage name, and his real identity is Kuon Hizuri.
Ren believes his love for Kyouko is unreciprocated. Due to his past as Kuon, he feels unworthy of happiness. He also denied his feelings for a long time because of their age difference. Kuon first met Kyouko at a creek behind the ryokan owned by the Fuwas when they were young. Kyouko is unaware that Tsuruga Ren, Kuon Hizuri, and her "fairy-prince Corn" are one and the same.
When Kuon attempted to start his acting career in America, he struggled to escape his father's shadow, Hizuri Kuu or Shuhei Hozu. His performances were often subpar, leading to frequent job losses. Lory Takarada, a family friend, offered Ren a chance to leave his past behind and become Tsuruga Ren.
In his past, Ren was frequently bullied for being half-Japanese and half-Russian. His friend Rick helped him during these times, but one day, when Ren was beaten up, he transformed into his darker self, Kuon, and used martial arts to retaliate. Rick came to help but instead urged Ren to regain control. One of the bullies fled, while Rick's girlfriend was pushed onto the road as a speeding car approached. Rick saved her, but the car couldn't stop in time, killing Rick. Tina blamed Kuon, calling him a "MURDERER," so Ren vowed never to revert to his violent ways and to renounce happiness forever. He wears a watch that stopped at 2:13, referring to it as handcuffs, to remind himself of this vow and the tragic incident.
