Former Top Idol
|Affiliation||Four Star Academy (formerly)|
|Anime||Beyond the Rainbow|
Hotaru is a former student at Four Star Academy, having been the Flower Song Class representative of S4 during her time. She is the first person to have experienced the mysterious power before Hime and Yume, and consequently lost her ability to sing due to relying on it too much.
Hotaru has long, wavy blue-gray hair tied up into a high, puffy side-tail with thick tented bangs to match. When she was an idol, her hair was straightened and worn with a white headband adorned with three stars - one blue, one pink, and one yellow. She has bright red eyes.
Hotaru is the opposite of her younger brother. She is perky, kind and social. She is also caring and soft.
Yukino (雪乃) Yuki (雪) means snow, and No (乃) is an ancient Chinese character now only used in names. It was used as a possessive particle, from which the hiragana character "の" evolved from.
Hotaru (ホタル) means firefly.
