Reona West is a PriPara idol and 7th grader at Paprika Private Academy, voiced by Yuki Wakai from i☆Ris. He's the twin brother of Dorothy West and has a mixed heritage—Canadian father, Japanese mother. His go-to phrase is "If Dorothy○○, me too." and he's loyal to the Fortune Party brand.
Reona's pretty shy and honestly relies on Dorothy to keep him going. He tends to mirror whatever Dorothy does, which works out since they share the same preferred brand—making them the first main characters in the franchise to do so. He showed up first as a cameo in episode 12, then became a proper character when he formed the unit Dressing Pafé with Shion Todo and Dorothy in episode 14.
Visually, he's got short light pink hair with a braid on his left side, deep pink eyes, and a freckle under his left eye. He wears a sailor's hat tilted to the right. He's actually the third pink-haired character in the Pretty Rhythm/PriPara universe, following Jae Eun and Naru Ayase from the earlier series.
As a side note, Dorothy and Reona are the franchise's first main character twins, though not the first twins overall—that distinction goes to Aira's younger sisters Uru and Eru. His name comes from the second note of the solfège scale.
