Birthday: April 14th Age: 18 Height: 160cm Weight: 51kg Blood Type: O Ruri is the priestess of Ishigami Village, the first human settlement the protagonist encounters, and one of the main characters. Basic Profile Status: Priestess of Ishigami Village (daughter of the former village chief, Kokuyo). Family: Has a younger sister, Kohaku. Age: 18 at the start of the story. Role and Key Episodes: The Sulfa Drug that saved her life. Since childhood, she suffered from a severe illness (later revealed to be pneumonia) and was in critical condition. She was completely cured by the "Sulfa Drug," a panacea created by Senku and his friends using the pinnacle of science. Successor of the Hundred Tales: As a priestess's duty, she has memorized the "Hundred Tales," 100 oral traditions left behind by ancestors thousands of years ago (Senku's adoptive father, Byakuya Ishigami, and others). This knowledge provided Senku with crucial clues to unraveling the mysteries of the past (such as the existence of the glass record). The "Three-Minute Divorce" with Senku: In a grand tournament held to cure her illness, Senku emerged victorious after many twists and turns and ended up marrying her. However, since Senku's goal was not marriage but obtaining alcohol (a medicinal ingredient) as a "wedding gift for the new bride," they divorced in just three minutes. True Personality: While she seemed fragile and demure when she was ill, after her recovery, she began to show a tomboyish side similar to her sister Kohaku, running energetically around the village. Appearance: Long blonde hair, blue-green eyes. Speech: Polite and slightly archaic, with a calm and gentle tone.
