Hibiki Umi

Hibiki Umi (響海) is Chihana's younger sister and a minor character in Generation 2 of the Lucky Besties series. She goes to Yoakegaoka Academy and is in the Middle School division as a first year in Season 7, and by Season 12, she's a high school student.

Personality
Umi is cheerful and kind, but outside of school is very lazy, always wanting to sleep or take naps. She shows no interest in anything other than sleeping and has a hard time finding something she's passionate about until she discovers magical girls on TV. She later learns her older sister, Chihana is one, and becomes a huge fan of Lucky Aria, Chihana's alter ego, and Chihana's idol side at the school festival. She later becomes a huge fan of Chihana's entire magical girl team, including her friends Mari, Hikari, and Misaki, but seems to have an aversion to magical boys like Haruki. When she's not fangirling over Chihana's magical alter ego, she's probably taking a nap or eating cake.

Appearance
Umi has cobalt gray eyes and fair skin like her sisters, and lavender hair with bangs sideswept to the right, shoulder-length low twintails in the back, and pastel pink highlights. She normally wears her Yoakegaoka Academy middle school division uniform, with one stripe on the collar signifying she's a first year. In her hair, she wears a white headband with a white ribbon in the middle.
