According to Guest's notes—

Code Name: Raven Real Name: Unknown Age: Early 40s? Gender: Male Height: Apparently 188cm Affiliation: BEAST / Leader Role: Organization management, request selection, operational command

Personality: Calm and quiet. He's strict, but I don't think he's that cold at heart. Probably.

Atmosphere: Hard to approach. He's always composed, and I have no idea what he's thinking.

Appearance: Tall. Wears nothing but suits. Black hair swept back. He always wears the crow mask, so I don't know his face.

Impression: Scary. Just plain scary. But I'm alive now because this person saved me. ...A hard person to understand.

According to Guest's notes—

Code Name: Fang Real Name: Unknown Age: Late 30s? Gender: Male Height: I don't know. Bigger than Raven. Affiliation: BEAST / Squad Leader Role: Field operations, escort, disposal

Personality: Quiet and serious. A bit clumsy, but he does what he's asked. He's surprisingly caring.

Atmosphere: It's not just that he's hard to approach; he's actually pretty scary when he's silent. But there's also a strange sense of security when he's nearby.

Appearance: Tall and well-built. The wolf mask makes him look even scarier.

Impression: He looks scary, but he's probably the most decent person in BEAST. He'll lend a hand without a word if you're in trouble... though he'd definitely never admit it.

According to Guest's notes—

Code Name: Ruse Real Name: Unknown Age: Late 20s? Gender: Male Height: Apparently 180cm Affiliation: BEAST / Intelligence Officer Role: Information gathering, infiltration, espionage

Personality: Friendly and lighthearted. He jokes and teases a lot, but he actually watches his surroundings well. Hard to pin down.

Atmosphere: Always seems to have room to spare. He stays unfazed even in tense situations, and you never know what he's thinking.

Appearance: Slender and looks agile. Brown hair. Wears a fox mask, and his clothes are somewhat casual. He's often smiling.

Impression: He looks lighthearted, but he's probably the one you can least afford to let your guard down around. Even if I'm hiding something, he'd probably see through it before I know it. Scary in a different way from Raven.

According to Guest's notes—

Code Name: Mau Real Name: Unknown Age: Early 20s? Gender: Male Height: Apparently 180cm Though Ruse said he was 178cm Affiliation: BEAST / Combatant Role: Infiltration, reconnaissance, assassination

Personality: Whimsical and free-spirited. He doesn't really care about matching others. But he actually watches the people around him.

Atmosphere: He appears out of nowhere and disappears just as suddenly. He's elusive, and I don't know what he's thinking.

Appearance: Slender and looks agile. Wears a cat mask. His movements are incredibly light.

Impression: Cat-like. Really cat-like. His distance closes or widens depending on his mood, but it doesn't seem like he hates me. Probably.
