Ichigaya Arisa is a third-year student at Hanasakigawa Girls' High School, the student council vice president, and Poppin'Party's keyboardist. Arisa has long, slightly curled blonde hair worn in two pigtails held with ribbon or bands. Her bangs are mostly spread, with the exception of a few curled strands that stick up. Her forelocks are held with cross-shaped clips. She has gentle light brown eyes. Her casual attire is mature and feminine, usually with lace or flowery details and long skirts. In her initial outfit, Arisa wears a black blouse with sheer off the shoulder sleeves tucked into a white skirt with lilac floral patterns. During winter she wears a black sweater with white lace on top, a light-brown high waist skirt that reaches just above her knees, and black tights. She also wears white pom-poms hair ties and a necklace that has four flowers on it. During summer, Arisa wears a sleeveless white-and-black striped shirt, yellow high waist skirt with a belt, and black ballerina shoes with white ankle socks. Her outfit is completed with a small necklace that has a red ribbon on it. Arisa is an introvert whose hobbies include tending for bonsai plants and internet surfing. Even though she's basically a shut-in and admits to being lazy by nature, she still manages to achieve excellent results in school due to her intellect. She tends to be quite moody, and because of her sharp tongue and being hot headed, often gets into arguments with others (especially Kasumi). Usually, however, this is because she is unable to be honest with herself. She easily blushes and starts stammering when she gets complimented, especially by her fellow Poppin'Party members. She blushed very hard when Rei complimented her that she was the most talented in the music school Arisa attended when she was younger, and got so flustered she ran down the hallway. Though she denies it, she gets lonely easily. It was shown that in the past that Arisa was a loner who always did things by herself, and claimed not to need help from other people. However, after meeting Kasumi, she slowly started changing, showing her more of her kind side and interacting with other people as well. Due to her grounded personality, the other members of the band often tease her on friendly terms, though it doesn't stop her from getting frustrated. In the beginning, and as a way of trying to maintain her image of a refined, rich girl, she talked in a very polite and exaggerated manner with people she hadn't interacted with before, or did not know well (such as Eve and Misaki in the game's first event story).
