As her hero name implies, she is very shy to a near crippling degree. She is a compassionate and pure-hearted girl who exudes more of her power when she is helping others.

As the hero Shy, she wears a white bodysuit with a white eye visor, twin-tailed hood, and gas mask. She usually wears glasses while in civilian form, but not as a hero. She has the ability to turn the Heart Power from her Heart-Shift Bracelets into flames.

Amarariruku

 * Stigma (スティグマ) / Mei Momijiyama (紅葉山 明) / Shine (シャイン)
 * Stigma is the leader of Amarariruku. The name "Stigma" is what Unilord and other heroes call him, which he later accepts and uses it for himself. He is extremely abstract and childish, even refusing to mature. He wishes to create an adult-free world, one fit only for children. To do this, he formed Amarariruku by gathering ordinary civilians, taking their hearts, turning their wishes and desires into reality, and bestowing a name to all his creations. He uses rings which were made from parts of his heart which cause his creations to go on violent rampages. The rings have powers similar to the Heart-Shift Bracelets. He can also attack his opponents using dark power crystals.
 * It is revealed later in the story by Iko that Stigma's existence may be the cause from the darkness in the heart of Teru's late sister, Mei Momijiyama, the former hero of Japan, who used the hero name "Shine". The ties between Mei and Amarariruku are that they were all people Mei met in her travels that she was unable to save and ultimately passed on. Mei herself gave her life protecting a group of children in a car accident and Teru's desire to see her again led her to becoming a superhero. The members' names and the group's name itself come from each person's personalities and Mei's unique way of using abbreviations, and "Amarariruku" is a shortened form of the phrase "The Sky Away from the Rain" (雨から離れた空), a name given to an umbrella used as a good luck charm by Mei and Teru.
