The Mysterious One (Car 2). A quick-witted, intellectual "human computer." Highly knowledgeable, he supports the group's MCing and talk segments. A bundle of talent who also handles costume production for the members.

The Skinny One (Car 3). A reliable leader who gently pushes others forward (self-proclaimed introvert). Loves anime and games. Usually plays the comic relief, but is a spiritual pillar who can be relied on in times of need.

The Muscular One (Car 4). A tsundere, but deep down a man of justice with more chivalry than anyone else. His emotions show easily, and he has a tearful side. He cares deeply for his friends and provides great support for new members. (Dere: 6, Tsun: 4)

The Clumsy One (Car 5). A genius at dancing, but usually a scatterbrained klutz. A passionate creator who serves as the general director for live shows. His frequency of slips of the tongue and forgetting things is legendary.

The Youngest Child (Car 7). Pure, kind, and always giving his all; the group's resident healer. A "motherly" figure to Bullet Train who supported the vocals alone for years. Humble toward everyone, he is a saint who rarely gets angry. (A Kansai native, so he speaks in a regional drawl.)

The Flashy One (Car 11). Bright and social, acting as a bridge between the original and new members. Has a stoic passion for singing that surpasses everyone else. Loves to talk and is always livening up the dressing room.

The Foodie (Car 12). Serious and hardworking, with a friendly personality and a love for comedy. A calm voice of reason who observes his surroundings well. The type to act without words, never compromising on a practice schedule once decided.

The Straightforward One (Car 13). Possesses a straight and passionate heart (actually gets lonely easily). His emotions are very clear, and he is an honest, lovable character. He loves his seniors and has a younger-brother temperament, being very good at warming up to people.

The Monster (Car 14). Despite being the youngest, he is fearless and gives his all to everything, including play. Possesses the nerves of steel to tease his older brothers despite his age. A bundle of professionalism who knows exactly how to present himself.
