Description
Riina Tada is a 13-year-old Tokyo native with beige hair, aquamarine eyes, and a height of 152 cm. Her measurements are 80-55-81 cm, blood type A, and birthday June 30 under the Cancer zodiac. She embodies a royal blue theme color and cool idol classification. Rock 'n' roll music dominates her hobbies, fueling her passionate dream to become a rockstar. She frequently channels her ideal rockstar persona despite lacking deep knowledge of rock music or industry dynamics, approaching both her ambitions and idol work with unwavering earnestness.

Riina shows consistent respect toward elders. Initially informal with the Producer, she adopted honorifics after valuing his guidance. Her admiration for Natsuki Kimura evolved into mentorship, culminating in their unit Rock the Beat. She participates in multiple collaborations: * (Asterisk) with Miku Maekawa; Masque:Rade with Mayu Sakuma, Karen Hojo, Miho Kohinata, and Chieri Ogata; Rapiéçage with Mirei Hayasaka, Yuko Hori, Akira Sunazuka, and Asuka Ninomiya; Ao no Gakudan ~Azul Música~ with Rin Shibuya, Ranko Kanzaki, Kaede Takagaki, and Minami Nitta; and prologue notes with Izumi Ohishi, Yuuki Otokura, Yukari Mizumoto, and Nao Kamiya.

Her friendships include Ryo Matsunaga, Mayu Sakuma—with whom she shares noted closeness in Masque:Rade—and Yuka Nakano. Past collaborations emerged through bonds with Shizuka Mogami and Julia from D/Zeal. Riina is among several idols originating from Tokyo.
