shigure_ui_(student)
Previously unused design of Shigure Ui (Vtuber), according to her live streaming.
She is similar to Shigure Ui (Vtuber), such as same green eyes, but with black hair and white school uniform. In order to be distinguished from oozora subaru who also has black hair, the hair color was modified to light_brown in the final version.
In original music video 勝手に生きましょ and KV of her personal exhibition, this design seems to represent student_and_illustrator_Shigure_Ui before she became a Vtuber.
