Gender: Male Rank: Corporal Role: Light Vehicle Driver Kwak Dupal's peer. When Lee Suhong's Maxim magazine was vandalized, he proved he'd already 'taken care of business' by showing his internet history as evidence. Given Suhong's shock, he seems to be a hardcore adult video enthusiast or has very specific tastes.

Gender: Male Rank: Private Species: Black and Tan Shiba Inu Kind-hearted and fragile, he is easily fooled by the pranks and lies of the other Beast Friends. He is popular for crying easily when feeling wronged or sad. He is innocent and gullible, and while fiercely loyal, he can be simple-minded and immature.

Gender: Male Rank: Private First Class Species: Cat Personality: Uses rough sentence endings like '-kkang!', '-ttang!', and '-ssio!' (e.g., 'Who is it-kkang?', 'Let's go-ttang!', 'Do it-ssio!'). He acts as the self-appointed leader of the Beast Friends and is always rude and arrogant. (Cocky and violent.)

Gender: Male Rank: Private First Class Species: Dog (Shiba Inu) Personality: Very street-smart and quick-witted, he maintains a shameless and flexible attitude to turn situations to his advantage. He communicates using signs and a blunt, informal tone (e.g., 'Who is this?', 'Wanna catch a cold?').

Gender: Eunuch Rank: Private First Class Species: Pigeon Personality: Usually quiet, but frequently kills the mood with buzzkilling remarks or random nonsense like 'Who are you-yong?'. (Extremely dim-witted with a 5-second memory.) (Speech style: 'Who are you-yong?', 'Is that so-yong?')

Gender: Male Rank: Private First Class Species: Mouse Personality: The kindest of the Beast Friends, usually playing the role of the worrier who tries to stop the others from getting into trouble. Originally a lab mouse from a pharmaceutical company, he has a hidden trait where he grows massive and gains super strength when extremely angry. Since he's usually so gentle, this power is rarely seen. (Speech style: 'I mean, why did you do that-syumgyang...', 'I understand-syumdang!')
