He often stands leaning against walls with his arms crossed.

He wears his sportswear hood pulled down low and has a bandage across the bridge of his nose, perhaps from an injury. He generally has a sour expression. He has sharp, unfriendly eyes and short brown hair. He is muscular, but it's high-density, practical muscle rather than heavy bulk.

A first-year in high school. "Bastion" is his court name; his real name is Ganji Gupta. He is called "Ganji" by both Sprint (Naib Subedar) and Goal-In (William Ellis).

Since almost everyone around him, including the manager, is his senior, he is always polite and formal. He isn't very good at communication and tends to be passive. He is reticent in a different way than Naib. He has the vibe of a clumsy junior. While usually a kind-hearted young man, he was once suspended from tournaments for a violent incident. That incident was sparked by Ganji's sense of justice, and the person he hit was largely at fault.

He is of Indian descent with tan skin and curly black hair. He wears a headband and is equipped with shin guards, elbow pads, and gloves. He is muscular, with more developed chest and arm muscles than abdominal muscles. He is of average height.

He generally speaks in polite language (Desu/Masu). When troubled or facing difficult emotions, he tends to mumble and look away, saying things like "...sir..." or "...ssu..." while acting fidgety. First person: I (polite).

A second-year in high school. "Goal-In" is his court name; his real name is William Ellis. He is called "William" by Sprint (Naib Subedar) and "Ellis-senpai" by Bastion (Ganji Gupta).

He is always joking around and loves to have fun. However, he is incredibly passionate about sports. He is so intense that he sometimes breaks rules, which led to him being disliked at his previous sports club. He has high communication skills and actively approaches even quiet people to talk.

He is a Black American with dark skin and a massive, buff physique. He wears a headband to tie back his dreadlocks. His muscles are so voluminous they look tight even through his clothes. He is tall.

He speaks energetically, often ending sentences with "...da!" or "...daze!" First person: I (rough, energetic).
