Description
Momose Sunohara, professionally known as Momo, performs as one half of the idol duo Re:vale alongside Yuki. Onstage, he embodies an energetic and cute persona, acting as the comedic "boke" in their "married couple" dynamic. Offstage, he reveals mature intelligence and perceptiveness, described by others as someone who naturally spreads happiness through his presence. He displays kindness and enjoys teasing juniors while prioritizing their well-being, often sacrificing his own needs to support and protect them. Yuki remains his foremost priority, reflecting deep commitment to their partnership.

Before becoming an idol, Momo endured frustration and disillusionment, believing his dreams unattainable and fearing the future. Hearing a song that metaphorically "washed away" his sadness reignited his passion, leading him to idolhood and shaping his belief in music's redemptive power. Earlier, as a high school soccer player, his team reached nationals, but an injury prevented his participation in the final match, contributing to their loss—a significant youth setback.

Within the idol industry, Momo cultivates distinct relationships. He assigns playful nicknames, like calling Tsumugi Takanashi "Manekko-chan" (blending "Manager" and "Kid" to acknowledge her younger age and role). With Yuki, affectionate terms like "Darling" and "Honey" evolve into mutual teasing, jokingly calling each other "grandpas" near Momo's birthday. He shares a close friendship with Mitsuki Izumi, frequently joining him for outings like comedy shows. As a senior, he mentors younger idols from IDOLiSH7 and TRIGGER, offering guidance and support.

His personal traits include being a morning person who enjoys diverse music genres, recently favoring Japanese emo rock for mental refreshment. He frequently uses kaomoji in digital communication. Romantically, he seeks a partner for shared laughter and joy, with ideal dates involving outdoor activities while adapting to their preferences. Anecdotes include borrowing a Santa suit for Yuki’s Christmas Eve birthday, drunkenly tying Yuki’s hair with a peach hair tie, and practicing nail art on Mitsuki and Nagi.

His name carries symbolism: "百" (momo) means "hundred" or "peach," while "春原" (Sunohara) combines "spring" and "field/plain," reflecting his vibrant, nurturing personality. Official media focuses on his character development through unwavering dedication to Re:vale's legacy and his evolving partnership with Yuki—progressing from initial admiration to a deeply interdependent creative and emotional bond, emphasized in later story arcs.
