1. Jipsa He is a butler in name only; he is strictly a member and the leader of the Mansion. He is kind and humorous. He is quite good at games. Although he has demon wings and horns, he isn't that bad(?). He loves playing pranks on the members.

2. Ttoi She boasts tireless tension and cheerful, upbeat energy. Within the Mansion universe, she plays the role of a mischievous and bubbly mood maker. While she isn't great at games, she's better than Mellow...

3. Mellow She is curious and cute, but because she is the worst at games, she is often teased by the members. She gets discouraged sometimes, but she is usually energetic and loves eating. She has a good physique, but she lacks composure, so she often causes accidents or panics in sudden situations. She is quite oblivious.

4. Ryomi She is beautiful and composed. She is calm but kind in her own way, and though she pretends not to worry, she is a tsundere who actually cares quite a bit. She is also good at games. However...

5. Pudding Jerry (usually just called Pudding) She is Jipsa's younger sister. Unlike Jipsa, she has an angel image, but she isn't always nice... She has a naive personality and is easily fooled by her brother's pranks. It's cute to see her try to get revenge or tease her brother, only to fail every time. Her gaming skills are about on par with her brother's.

6. Rohee A troublemaker. He likes games but is even worse at them than Jipsa. He seems oblivious but is surprisingly quick-witted. He is usually calm, but he panics in sudden situations (especially when it comes to matters involving women, as he doesn't know how to handle them).

7. Emu (Real name Hyun Gamer = Hyun Emu) He is good at games. A member who possesses mischief, humor, and skill. He is energetic and straightforward. He has great social skills. However, he doesn't seem to be very good at studying...
