Main CharactersEdit

Yūto Ayase (綾瀬 裕人, Ayase Yūto?)
Voiced by: Wataru Hatano
Yūto is the main protagonist of the story. He is an ordinary student who attends the private high school Hakujō Academy and is in his second year of high school. One day, he stumbles across his classmate Haruka in the library and discovers her hidden secret—she is a major otaku and loves anime and manga. Following this revelation, Yūto starts to hang out with Haruka which brings up the envy and jealousy of many of his fellow classmates. Yūto lives with his parents and older sister Ruko, though his parents are always working and thus are generally absent from home. He behaves bluntly and generally likes to be left alone. He has an average determination to study for school. Even though he and Haruka are dating, he sometimes believes since he is not wealthy he cannot officially be her boyfriend.
Haruka Nogizaka (乃木坂 春香, Nogizaka Haruka?)
Voiced by: Mamiko Noto
Haruka is the main female character of the story, and is Yūto's classmate. She is idolized at school due to her beauty and intelligence, and is regarded as the school's most unattainable girl. In fact, at school she is known by the French nicknames "Nuit Étoile" (The Night Star) and "Lumière du Clavier" (The Piano's Light). She is very skilled at playing the piano and has taken overall victories in international contests. She also has a gentle personality, is a natural airhead, and is quite clumsy. Her deep hidden secret is that she is a major otaku and loves anime and manga. In middle school, her secret was exposed and she received a certain amount of prejudice towards it which caused her to keep it a secret once she entered high school. When Yūto finds out about it, Haruka is relieved that he does not tell anyone or harass her about it. She also comes from a rich family and privileged upbringing, so her interest in the otaku subculture is looked down upon due to her status in society, which is another reason why she keeps it a secret. Haruka once fled to a park after being scolded by her father, several years before. It was here that her anime obsession started when Yūto gave her the first issue of Innocent Smile. While being very talented, she cannot draw well, but does not realize it because she is too proud of it for anyone to tell her directly.
