Hiko is Naruto's twin sister. Despite being twins they are polar opposites, Naruto is childish, Hyper and airheaded while Hiko is Mature, lazy and intelligent. Hiko is the spitting image of her mother with bright red hair, a round face and blue eyes while she acts a lot like her father. Just like Naruto, Hiko's name was taken from Jiraiya's novel tales of a gutsy ninja. The original name was Yahiko but Minato and Kushina shortened it. Trigger warning - mentions of depression, suicide and self harm
