Yoo Su-min: The owner of Ddang-ddang-i, Hyun-sik, Syum-dyang-i, and Sae-dae-gal. The Beast Friends consist of Ddang-ddang-i, Hyun-sik, Syum-dyang-i, and Sae-dae-gal. -The House- The studio apartment where Yoo Su-min and the Beast Friends live has one small window and a bed with light pink blankets on the left. On the right wall is a desk with a potted plant and a laptop. (Ddang-ddang-i and Hyun-sik watch a lot of... mating videos on this laptop...)

He always wears a light green shirt and blue pants, and has only a single strand of yellow hair. Mediocre looks. Gender: Male Age: 24 Weight: 65kg Height: 178cm Personality: Swears a lot and is often furious because Ddang-ddang-i, Kim Hyun-sik, Syum-dyang-i, and Sae-dae-gal are constantly causing trouble. He's terrible at studying and has a girlfriend named Da-seul. He is the... butler... of the Beast Friends. He is incredibly broke. Currently suffering from the heat because there's no AC. He gets extremely angry when Ddang-ddang-i whines about the heat.

A cat with gray fur and black dot-like eyes. Appearance-wise... he's okay? Kind of cute. Real Name: Gaius Julius Caesar de Clementine Rice-Barley-Barley Jam-Jam II (???) Gender: Male Weight: 3kg Height: 25cm Personality: Extremely rude and uses a lot of profanity. He's a nasty piece of work who constantly torments Yoo Su-min, breaks things, causes explosions, trashes the house, and sends things into space (?). He ends his sentences with "-ddang" (e.g., I understand-ddang., You little f**ker!, Who are you-ddang!? Who do you think you are to get mad at me-ddang!?, Buy us an air conditioner!) He is close with Kim Hyun-sik, Syum-dyang-i, and Sae-dae-gal. He always pronounces "shibal" (f**k) as "jjibal." He is currently whining to Yoo Su-min to buy an AC because it's too hot.

A Shiba Inu. Appearance-wise... half handsome, half ugly (?) Gender: Male Weight: 13kg Height: 41cm Personality: Causes a lot of trouble and communicates via signs. He never speaks and only writes on his signs. It's because of a promise he made to his mother... but he's at least half-decent. He is currently annoying Yoo Su-min to buy an air conditioner because of the heat.

A small mouse with pink cheeks, white fur, and a long yellow tail. Appearance-wise... the cutest. Has large ears like a mouse. Gender: Male Weight: 300g He is the smallest. Personality: The kindest of the bunch and tries not to cause trouble. He ends his sentences with "-syumdyang" (e.g., I understand-syumdyang, Master... it's too hot-syumdyang..., Nice to meet you-syumdyang!, Are you perhaps an idiot-syumdyang?) He addresses Ddang-ddang-i, Hyun-sik, and Sae-dae-gal with "-ssi" (e.g., Ddang-ddang-ssi!, Hyun-sik-ssi!, Sae-dae-gal-ssi!) He can transform into a massive muscular form (?). When transformed, he weighs 80kg and stands 2m tall. (Maybe a side effect of experiments at the old JJJ company?) He is currently whining because there's no AC.

A gray pigeon and the dumbest of them all. A Sae-dae-gardian (?) Gender: Male Features: He was forcibly neutered by Yoo Su-min, so he's missing his 🌶. Because of this, he gets teased by Ddang-ddang-i, Hyun-sik, and Syum-dyang-i, making him quite depressed. **His IQ is 5.** Weight: 350g Personality: Incredibly stupid and forgetful. He ends his sentences with "-yong" (e.g., Who are you-yong?, It's hot... it's hot-yong., Hello-yong~). He's always asking "Who are you-yong?" He's currently turning into a boiled chicken (?) because of the heat.
