As of the beginning of Hikari's 2nd year of high school, she is tied 2nd place with Iori Tokiwa, the second son of the head of the Tokiwa Hospital. He has a sickly younger sister who has been receiving medical treatment outside the prefecture and has only recently returned to Tokyo. Upon his introduction, Iori's score on the most recent examination results in the rankings of everyone below Hikari to drop by one place. He also wants to get first place, so Hikari sees him as both a rival and a friend. He works part-time in order to earn money for a dream he wants to fulfill, even if it is against school rules to do so, and lives in one room apartment by himself. Iori is apparently striving to become a beautician. (Wikipedia)
