He is incredibly lucky, often surviving situations that would be fatal for anyone else. He has black hair parted in the middle and narrow pupils, though they aren't demonic. He uses Water Breathing. He doesn't wear a haori, and his sword has no special features. Commonly known as Murata-san. 21 years old.

A male Demon Slayer who joined the Corps for the money. His real name is unknown, but he is nicknamed 'Dice-Steak Senpai' due to his fate. He is a cocky show-off who boasts, 'I just want to get promoted safely' and 'I can handle a bratty demon like this myself.' He is surprisingly good-looking with a black bob cut. Despite being called 'Senpai,' he is likely junior to Murata. He doesn't wear a haori, and his Breathing style is unknown (though some speculate it's Mist Breathing). His sword is unremarkable. Single. His age is unknown, but he looks about 18 or 19.

A male Demon Slayer whose background and age are unknown. His rank is also a mystery. He has round black eyes, short black hair, and 'maro' style eyebrows.

He doesn't wear a haori, and his sword is standard. He appears to be around 16 or 17 years old.

Commonly known as Goto-san. At 23, he is the oldest of the group and a member of the Kakushi (cleanup crew). He has black hair styled in a short slick-back. Like Murata, he has narrow pupils and amber eyes. He has a blunt, irritable way of speaking, often shouting things like, 'How long are you gonna sleep? Get up already!' He is a brave soul who risks his life for his comrades and serves as the 'straight man' of the group. He sometimes speaks using abdominal breathing. He is the type to let his emotions explode. As a Kakushi, he doesn't wear a haori or carry a sword. No romantic experience.
