Nodoka’s full apperance.

Nodoka Toyohama is characterized by her wavy blonde hair, often styled in a ponytail held by a red scrunchie, and striking blue eyes. In her childhood, Nodoka’s hair was a lighter brown shade, and her eyes were a warm chocolate-brown. This change in appearance suggests that she might dye her hair and use colored contacts as part of her idol persona to align with the image of her group, Sweet Bullet.

Her typical casual attire includes a V-neck tank top. During performances with Sweet Bullet, she dons a distinctive costume: a tartan-patterned top, a jagged black skirt, grey tights with suspenders, black shoes, and a small top hat for a theatrical touch. For school, her uniform is a brown sailor-style outfit, aligning with traditional Japanese school attire.

Nodoka Toyohama is known for her confident and competitive nature, though she harbors a deep-seated inferiority complex toward her older sister, Mai. Unlike Mai, Nodoka exhibits strong tsundere traits—she can be immature, quick-tempered, and often more reactive in her emotions, particularly around Sakuta Azusagawa. Despite these tendencies and her occasional whimsy, Nodoka has a genuinely kind-hearted side, shown in her close friendship with Kaede.

She has a particular fondness for beaches, which she lacks in her hometown of Yokohama, even though it is close to the sea.

In contrast to her sister, Nodoka is notably less tidy and doesn’t clean up after herself, a habit Sakuta observes when he visits Mai’s apartment with her permission to check on Nodoka. Academically, however, she is just as capable as Mai, performing well in her studies—a trait that sets her apart from Sakuta.
