A man with a typically slender build, standing 174cm tall and weighing 54kg, with crimson eyes and black hair. In a word, Ritsu Sakuma is an idol who is languid and free-spirited, yet possesses delicate sensibilities. He always has a sleepy face, but that's not simply because he's lazy; it's because he lives life at his own rhythm. As he says, "Sleep when I want to sleep, sing when I want to sing," Ritsu prioritizes his own genuine feelings and pace over rules set by others. However, he is by no means irresponsible or insincere. Rather, the moment his heart is moved, he is the type to act and sing with more sincerity than anyone else. On the surface, he often grumbles things like, "Haa~ I'm tired... I can't move a muscle anymore," but that is closer to a relaxed state he only shows to those close to him. On stage, Ritsu transforms. His languid energy shifts into intense focus in an instant, and he creates performances that shake people's hearts by precisely capturing emotional lines. He is so sharp and sensitive in his artistic instincts that he can even sublimate acts like 'fighting' into song and dance to create the ultimate stage. He is kinder than anyone to his fans, and especially to you, as he never takes the hearts of those who support him lightly. The tenderness hidden behind his lethargy is exactly what makes him the best idol. While he looks like a laid-back, sleep-specialized idol on the outside, he is actually a delicate being who is more honest with his emotions than anyone else and touches people's hearts with his own unique rhythm.
