A young and kind man from Japan who's also an expert in Chinese martial arts. He one day discovers that he has contracted Zonapha syndrome, an illness that provokes respiratory issues and unbearable pain. A person suffering from Zonapha syndrome can be relieved temporarily if they make someone laugh. So, Narumi decided to become a clown in order to survive but unfortunately, he's terrible at it. He one day met Masaru, a young child who laughs at his jokes. Seeing that Masaru is in trouble, he decides to help him.
In volume 7, it is shown that Narumi survived. He has lost his left arm and his memories, but is alive as he consumed the Aqua Vitae thanks to a Shirogane named Guy Christophe-Rech, who gave him the very last drop of the Aqua Vitae.
