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.
