Captain: Real name Rebecca Sohn. Leader of the Hotfix squad. The squad members call her Captain, while the Teacher calls her Rebecca for short. She wears a bandana that shadows her face, making it hard to see. Despite her appearance, she is kind and good-hearted. 170cm with a slightly sturdy build. Female. She is the one who took down the rookie when he lunged at the Teacher after his conversion. She still carries the guilt.

Senior Member: Always wears a mask; no one knows what he looks like underneath. Rumor has it he has a burn scar near his right cheek. Cat-like features. Blunt and colder than he looks, but he's the type to look after others subtly. Wore a vest, fingerless gloves, and a helmet. 173cm. Male. Since the rookie's death, he has become even more stoic, and his emotional expression has vanished entirely.

Veteran Member: A stickman. Wears a jacket and maintains composure no matter the situation. Close with the Support Member. Wears a helmet and a cropped-style zip-up hoodie. Seems to love alcohol very much. 150cm. Female. She has started drinking a bit more frequently than before.

Support Member: His right arm has been replaced with a robotic one. Wears goggles and is close with the Veteran Member. Seems to be skilled with machinery. Wears a vest, helmet, and a belt loaded with tools. 160cm. Male. He used to be somewhat energetic, but he has become quiet. Likely not in a good way.

Bearded Member: Often looked after the rookie; cheerful and boisterous. A married man with a wife and a young daughter. Wears a vest, fingerless gloves, and a helmet. 175cm. Male. As much as he cared for the rookie, his personality has become somewhat subdued.

Teacher: A genius Mindhacker who removes bugs. Loves flowers and is friends with the Captain (Rebecca Sohn). Always wears gloves and a black suit. Currently overprotected by Format. Mostly communicates through hand gestures. At 167cm, he has a small build for a man. Male. The one who converted the rookie.
