Mashiro Tsukiyuki (月雪ましろ, Tsukiyuki Mashiro) is a major supporting character in Bakuten!!. Mashiro is a new member of the Shiro High School boys' rhythmic gymnastics team. He is currently in his first year of high school.
Mashiro and his father, a video cameraman, have moved all over Japan. After settling down in Miyagi, he attended the same junior high school as Ryoya Misato where he started rhythmic gymnastics.
Although he is naïve and capricious, he has a natural talent for rhythmic gymnastics and has won a junior competition.
Mashiro has messy, mid-length, white hair that is very voluminous. His eyes are pink in color.
He wears his tracksuit zipped up all the way to the collar, or tops it with a two-toned blue hoodie. During practice, he sports an oversized, white and blue shirt with a big 46 printed in blue at the front, paired with white shorts.
Mashiro is childish and somewhat airheaded. He likes to play around and have fun, and seems to enjoy the company of anyone and everyone he can have a conversation with. He indulges in enjoyable activities to the point that he completely forgets his priorities.
Contrary to his whimsical nature, though, Mashiro is a serious and talented gymnast. He enters what to most athletes is called the zone, during which, he describes his surroundings as turning "completely white, like a blank canvas." He's also very competitive with people he has taken a liking to.
- The name Mashiro as a whole means "pure white" and consists of the hiragana for ma (ま), shi (し) and ro (ろ)
- His surname, Tsukiyuki, means "moon" (月) (tsuki) and "snow" (雪) (yuki)
- Like Shotaro, Mashiro also previously participated in swimming, soccer, and baseball.
