Subaru

Subaru is extroverted and tomboyish in nature. She is confident, hardworking, and always optimistic, even in situations that would discourage most people. This is in part because she is likely the one holoIdol who has gone through the most trouble in her early life, as she was born with a hole in her heart (a Ventricular Septal Defect or VSD, which means the wall that separated the left and right side of the heart didn't close correctly and created a hole) that threatened to kill her by the time she was 14, got ran over by car and even had her house burned down, which was the final straw that pushed her desperately into joining hololive, going so far to pretend to be an otaku to get accepted, which was successful yet ineffective due to its fakeness.

Because of her overwhelming life experience, she usually acts like a tsukkomi (straight man), pointing out the ridiculousness of whatever other members are saying or doing, and in doing so makes her the butt of many jokes. But that doesn't mean she is incapable of smiling, as she always finds a way to smile and joke herself.

She has a silly habit of saying "shuba shuba shuba" to express excitement or contentment.

Subaru has a stereotypical tomboyish appearance, accentuated by her short hair, and her baseball fan attires, with a red with white cap turned backwards, a white and yellow-striped jersey, accompanied by a blue pea whistle, white and red shorts, a pair of thigh high socks, one white and the other red, and a pair of white tennis shoes with yellow laces. she has tied to her left hip a yellow hollow plastic megaphone (used in chants during baseball games) with a yellow piece of fabric.
