Tsuki Watanabe

Tsuki Watanabe is a supporting character in the Love Live! Sunshine!! The School Idol Movie Over The Rainbow movie. She is You Watanabe's first cousin.

Background
Tsuki spent most of her childhood days in Italy. After which, she returned to Japan where she studied high school.

She is a second year student who serves as the Student Council President at the new school where the transferees from Uranohoshi Girls' High School will be attending after they integrated from Seishin High School. When majority of the student body was reluctant to accept the transferees, Tsuki stepped up to help them settle in by helping Aqours.

Through their combined efforts, the student body eventually accepted their new schoolmates. Tsuki led her fellow students in helping a hand with Aqours' live show in Numazu.

Appearance
In her first appearance in the movie, Tsuki sports a tomboyish look, hiding her hair beneath a cap and wearing a coat and pants. Her cousin's friends—and to an extent the viewers—didn't realize that she's female until she removed her cap.

Despite her preference for this look, she sometimes wears skirts, like in her uniform and travel wear in Italy.

She has straight black hair that reaches her shoulders and purple eyes.

Personality
A dependable friend and fond of uniforms, Tsuki shares many qualities with her school idol cousin. Of the entire student body, she was the only one willing to help the transferees be accepted into the new school.

Having grown up in Italy, Tsuki is fluent in Italian.
