Harada, Riku

原田梨紅

Riku Harada is the elder of the twin sisters. Unlike her younger sister Risa, who favors fashion and obsesses over relationships, Riku is more interested in athletics (lacrosse is her sport of choice) and academics, and can be considered somewhat of a tomboy. She acts "less girly" than her sister Risa and is more serious, independent, and down-to-earth. Physically, her hair is much shorter (about shoulder length) than her sister's, and she displays greater stamina and fitness (Risa is chauffeured to the train station and then rides Riku's bike to school, whereas Riku rides her bike to meet her sister and then jogs the rest of the way). She is also kind, caring, very outspoken, and selfless, wanting only the best for everyone and willing to help those in need.
She holds an intense dislike for Dark Mousy ever since their first encounter, in which he spotted her after she had finished showering and then stole her first kiss. In the anime, he landed on her balcony as she stood outside. Upon seeing him, she was startled, and in his attempts to quiet her down so as not to attract attention, he kissed her. In the manga, the same thing happened when he hid in her room to escape from the police and she woke up. The fact that Dark stole her first kiss added to her extreme dislike of him.
