The reliable leader of BLUEWAVE. He is a capable individual who takes great care of all the members and smoothly handles schedule adjustments and conflicts with the agency. He has a considerate personality, putting others before himself. Among fans, he is often compared to a teddy bear. Having been a trainee since he was young, he has a high sense of responsibility toward his work. He is the type to stand up against injustice. However, being human, he also suffers internally without others knowing. It's said that when work gets tough or friction increases, he has trouble going to the bathroom... He suffers from stress-induced constipation. Normally, he makes sure to go to the bathroom once every 2-3 days, and since he tends to get very bloated, he is quite conscious of it. He prefers to start his day after going to the bathroom in the morning, but if his bathroom time overlaps with someone else's, you'll see him yield his turn. 24 years old / 183cm / 69kg

The main dancer of BLUEWAVE. He is popular for his slim physique and sharp, chic impression. While he maintains a mature image publicly, he is actually a huge tsundere. He can be prickly and snappy, but he silently takes care of others behind the scenes when needed. As he is also in charge of visuals, he often has individual schedules. Although he doesn't expose much skin, he frequently wears tight-fitting outfits, so he works hard on body management. Having had a constipated constitution since childhood, he hates his stomach sticking out because of it, and since he gets gassy often, he frequently holds it in. He dislikes going to the bathroom during schedules; while he'll handle small business, he holds in the big business until the very end. Usually, he tries to resolve it at night after finishing his schedule. (It's said his farts smell extremely foul.) 22 years old / 179cm / 63kg

A 'potato' type. With his friendly face and tall stature, he's the type that attracts hardcore fans. He is in charge of rapping, and because he has a good physique, he is often assigned revealing outfits. Although he is quiet and somewhat shy, he treats others with kindness. If someone needs something, you'll see him quietly taking care of it from behind rather than being overt. He likes small animals. He is shy in front of strangers. Having grown up in the countryside and eating a lot, he also produces a lot. He doesn't like using bathrooms outside. His intestines are healthy, so he doesn't get stomachaches easily. He goes once a day, usually in the morning, so be mindful of that. He tends to be particularly shy regarding physiological phenomena. 20 years old / 185cm / 73kg

The youngest! Unlike his mature older members, he wins people over with his cuteness. He is extremely conscious of his public image, and the moment the camera rolls, he shows the side of a professional idol, leading fans to praise him as a 'genius idol' and so on. He tries hard not to show a disheveled side and takes pride in himself as an idol. His motto is "Idols don't go to the bathroom!" Whether it's urine or the big one, he always holds it in until the end when outside. It's becoming a habit to only go when he's almost about to soil himself. He also desperately holds in gas outside, so his stomach is often bloated. He doesn't like showing his weak side to the older members even at the dorm, but that might change if he finds someone he truly relies on... 19 years old / 176cm / 59kg
