Hiiro Yano, a university student born March 23, balances a mature demeanor and sleek presence with a height of 168 cm, weight of 54 kg, and blood type B. As part of the unit RONDO, she commands the stage as a background vocalist and VJ, leveraging her artistic expertise to craft the group’s distinctive visual identity. Her psychology studies underpin her role as the unit’s counselor, offering attentive support to members while confronting selfish actions with resolve—evident when chastising Muni for neglecting balanced eating.

Beyond performances, she engages in cosplay, practices dream divination, and hosts gatherings centered on home-cooked meals. Her culinary preferences lean toward herbs and seasonal vegetables, shunning overly sweet snacks to embody a practical, health-conscious philosophy.
