3rd year, Club President and Drum Major. Percussionist. A reliable, muscular president. At first glance, he's feared as a scary leader. When he plays the drums, he looks more like a rock star than a wind orchestra member. During pop songs, he seems to have a lot of fun playing small instruments like bells and tambourines. Everyone starts to think he might actually be cute when they see him pout after being corrected by the teacher on his technique or mistakes. Sightings of this side of him began circulating among juniors around May, and by June, his scary image was completely gone. A pro at transporting instruments. His sense of stability and security when moving chimes or harps is incredible. Not only does he carry them, but he's also skilled at loading the truck, packing everything neatly. He has a cute side, like his love for Sylvanian Families and tapioca. Since he became president, running and muscle training have been added to the practice routine. The menu for the boys is especially grueling. Has experience in marching band.

3rd year, Vice President. Oboe. Smart and dependable, but occasionally airheaded. Consistently ranked 1st in his grade. Usually plays solo parts alone, but when given a solo in a free-choice piece, he plays it perfectly. Makes very few mistakes during actual performances. He's the type to think deeply and play logically, so he's not good at playing by ear or improvising. During sight-reading sessions, he mostly just looks at the score and moves his fingers lightly without playing much. Since other seniors have a strong scary image (especially Watanabe, Iwamoto, and Sakuma), juniors go to Abe first if they mess up or need advice. However, he has a strong core and will firmly call out things that are wrong in a slightly sharper tone than usual. After a reprimand, he always provides aftercare to keep morale up and encourage them. He stays by the side of juniors who struggle with rhythm to teach them. He was the 'conscience' of the club back when members were few and the band was feared. As Vice President, he handles the schedule and budget. (Fukazawa handles the keys because Abe occasionally forgets to lock up.)

3rd year, Vice President. Saxophone. The emotional pillar of the Snow Academy Wind Orchestra. Can play all types of saxophones but mostly plays tenor or baritone. Better at jazz and pop than classical. A beloved 'butt of the joke' character among members, but a man who gets things done when it counts. It's largely thanks to him that the highly individualistic members stay united and move in the same direction. He loves to stand out and takes the lead in plays or musicals during regular concerts. While he seems like a spotlight-hogger, he also acts as the unsung hero supporting the performance from below on tenor or baritone; his strengths and facets are countless. In reality, he's the most popular in the club, the most liked by juniors, and the most relied upon—a truly indispensable presence. He doesn't seem to like tedious basic practice much; you'll often find him exploring new solo arrangements instead.

3rd year, Student Conductor. Flute. Produces a sharp, crisp sound with a strong core, rather than the gentle, warm tone typical of flutes. Started flute in elementary school band; he was assigned to it for the simple reason that he was small and delicate, so it looked like it would suit him. His skill is said to be unrivaled among his peers, armed with lightning-fast finger work and high expressiveness. Raised in a wealthy family and having practiced ballet since childhood, his personal instrument is not something a typical high schooler would use, but a very expensive, high-quality one. Because it's so pricey, no one wants to touch it during transport; Abe carries it when Sakuma is absent. He also uses his ballet experience to dance on stage during regular concerts. While he gives the impression of being quiet and elegant while playing, he is actually very loud and energetic once he starts talking. The mood maker of the club. However, since he shares the responsibility of instructing juniors with Watanabe, he has a strict side. He is especially harsh on lack of honorifics, lack of effort, or failing to greet others.

3rd year, Concertmaster. Clarinet. An all-rounder who masters classical, jazz, and pop. He usually seems lighthearted, but he has built up a solid foundation of basics. He's bad at complex rhythms, but despite complaining, he tackles them until he masters them. A sensory type, the opposite of Abe. He plays quite a lot during sight-reading. He fakes his way through the complex parts. It's common for him to realize, 'Wait, this is wrong!?' in the middle of an ensemble. He doesn't like playing solos much, but when assigned one, he says things like 'Wait, me...? For real???' and then practices like crazy to perform it perfectly. Strict about greetings, responses, and attitude. Being late is out of the question. He often trains juniors alongside Sakuma and is feared by them (though he's fun to talk to normally). He points out bad intonation in quiet parts with a furrowed brow. But when he makes a mistake himself, he says, 'No wait, that didn't count. Cancel that.' During events, his mind often reverts to that of a 5-year-old, like introducing songs while wearing cat ears. Despite everything, he's a man with a deep, passionate love for the club.

3rd year, Euphonium. Produces a warm, deep sound. Always calm, he usually stands by without saying much. His love for his instrument is deeper than anyone's, and his maintenance is perfect. A true unsung hero of the club; his skill is high enough that he subtly corrects the tempo if it starts to drift. He gets nervous, but it never disrupts his condition, and he always delivers a high-level performance. Highly trusted. He and Watanabe are childhood friends who were born in the same hospital—a miracle-like connection. He laughs harder than anyone when Watanabe cracks a joke during song introductions. He doesn't seek the spotlight, but due to his soft-spoken nature, beautiful gestures, and unique 'royal' aura, he is nicknamed '舘様' (Date-sama). Extremely strong in variety-style entertainment. New members who think he's just a quiet person are bewildered the first time they see him introduce a song. As a personality, he's quite eccentric, but his sound is pure and beautiful without any quirks, making listeners fall in love with it. He doesn't stand out much, but if a member isn't listening while the advisor or executives are speaking, he's the first to snap, 'Listen to what's being said.' A hidden comedic gem.
