Seiji Hiwatari (日渡 星司, Hiwatari Seiji?) Voiced by: Souichiro Hoshi
A member of SHIPS, as well as Kirari's love interest. Very rich. His parents disagree him of being an idol. Throughout the beginning of the series, he seems oblivious to Kirari's feelings, but by episode 12 he begins to portray feelings of jealousy over Hiroto's and Kirari's friendly relationship. He is gentle and says very encouraging words to Kirari. Since he is as dense as her, he always has a calm and clueless expression. When he is wandering around in the city, he disguises himself as an otaku.
Kirari Tsukishima, a gluttonous 14-year-old beauty, is a girl who does not care about idols and the entertainment world because her mind is occupied by food. Her obsession with food only causes her to be clueless about love, as she only wants a boyfriend who would feed her with delicacies. One day, after saving a turtle that is stranded in a tree, Kirari meets with a handsome and gentle boy named Seiji, who gives her ticket to a SHIPS (a popular idol group) concert to show his gratitude for her saving his pet. Kirari then storms off to the concert and runs into another boy, who tears up her ticket and warns her to stay away from Seiji because she and Seiji live in different worlds. The outraged Kirari then sneaks into the concert, only to discover that Seiji and the boy who tore her ticket, named Hiroto, are actually members of SHIPS. Finally understanding the meaning of `different worlds` (Seiji is a popular idol while she is an average middle school student), Kirari refuses to give up. Filled with determination to be with Seiji, she declares that she will also become an idol.
