ریکیو ناناسای

Riku is the center member of Idolish7. His vocal abilities and charisma make him the unit's secret weapon. He's innocent, yet energetic and cheerful. However, on the other hand, he's notoriously bad at making decisions, making him rely heavily on the collective agreement of his fellow members. Since childhood, he's suffered from a respiratory illness that has limited his performance. However, this hasn't stopped him from pursuing his dream of becoming an idol.

[Spoiler: The center of the TRIGGER unit, Kujou Tenn, is Riku's older twin brother, adopted by Kujou Takamasa and abandoned the Nanase family five years ago. This drives Riku to become an idol so he can gain his brother's recognition and fulfill his dream of singing alongside him on stage.]
