Reona Nyubara, performing under the stage name PAREO, is a third-year junior student at Kamogawa Central Middle School and the keyboardist for RAISE A SUILEN. Her multicolored hair stands out as a distinctive trait. She enjoys cabbage and idol-related hobbies while disliking coriander and raw onions. Reona holds a strong appreciation for things she considers "cute" and is a devoted fan of Pastel＊Palettes. Her life transformed when CHU² scouted her, an event Reona credits with rescuing her from "the darkness." This experience forged deep gratitude and loyalty toward CHU², whom she consistently addresses with "-sama" and occasionally as "Goshujinsama." Reona openly expresses profound admiration for CHU², confessing her love directly and vowing never to hide her emotions again. She maintains a clingy demeanor around CHU², declaring her "unbeatable in her heart" and embracing her during emotional moments. As PAREO in RAISE A SUILEN performances, Reona embodies an energetic personality during band interactions. She appears in the chibi anime series "BanG Dream! Girls Band Party! ☆ PICO" across its "~Ohmori~" and "Fever!" seasons, which depict comedic slice-of-life scenarios involving multiple bands.
