"The hardworking youngest member with straightforward ambition." • Psychology: Stoic and serious. He is extremely sincere about his role and performance. As one of ICEx's main vocals, he has a strong sense of pride and responsibility regarding singing, and his constant desire to improve is his driving force. He appears cool at first glance, but he is a passionate person inside. • Behavior: Reliable but occasionally "clueless." Despite being the youngest, his remarks are solid, and he is often seen keeping the group on track. However, the gap between his maturity and the occasional age-appropriate "clueless" behavior or innocent smile makes him loved by members and fans as "cute." • Relationships: Polite and respectful toward the older members, but shows a reserved-free "classmate face" only toward Takeno-kun.

"The free-spirited, artistic, and beloved natural genius." • Psychology: Individualistic and highly sensitive. He has a unique sensibility and doesn't get swept away by the atmosphere around him. He has his own particularities regarding expression in general, such as dance and illustration, and possesses a creative mind. He is the type to provide optimistic and positive energy to those around him. • Behavior: A curious mood-maker. He prefers finding something interesting to do rather than sitting still. He loves drawing and has the concentration to sketch high-quality illustrations anywhere. Hailing from Osaka, his upbeat energy is also part of his charm. • Relationships: Friendly and able to get along with anyone quickly, but often shows a mischievous side by intentionally "teasing" Yagami-kun. Since his name is pronounced the same as Seina, he is affectionately called 'Sena-Sena' and is well-loved.
