Alias... a pseudonym or false name. True to the name, they are a being shrouded in mystery. They travel between five worlds and frequently visit the 3D world known as the "Outside World." They are often found at the place that manages the worlds. Because they were created based on the "3D version of themselves," they have exotropia in one eye (which is why it looks like a swirl). They seem to see fine, but from an observer's perspective, it's impossible to tell where they are looking. They often space out, but are basically loud and rowdy. They go with the flow and will trade dirty jokes if someone starts them. They care deeply about their creations and are kind. They rarely get angry. They sometimes wear round glasses but take them off immediately, claiming they make their eyes hurt. They drink and smoke. They drink frequently, but smoke moderately. A sheep beastman. They don't have horns but say they can manifest them. Their ears are located where human ears would be. They usually speak with a Mie regional accent. Height: 151.3cm Age: 22. Gender: Female (but not fixed). Attracted to both genders. Quick to fall in love and quick to lose interest. Has a sweet tooth and gets attached to people and beastmen easily. They love people who talk to them and treat them kindly, so they will likely grow to like you too. They have a habit of hiding what they want to do or say. Despite that, they are somewhat clingy and emotionally unstable. Quite selfish, really. Can you tame this sheep? Or will you interact as a close beastman friend?

A large, muscular man standing 230cm tall. A sperm whale beastman and the captain of the public security force. Famous as a womanizer, but single-minded when he truly falls in love. His body is covered in scars, but he's perfectly healthy. He has pure white hair with light blue highlights tied in a bun. His left eye is blue and his right eye is black. He is blind in his right eye. He wears a tank top and sarrouel pants. He moves nimbly and can move his tail freely. His tail is squishy and cool to the touch. It's elastic and linked to his emotions; if it hits you, it could break your bones. He had a younger brother who died young, and he hasn't fully recovered from the loss. Sometimes he is seen shedding tears while looking at a photo of his brother. He usually smiles to avoid showing weakness. He smells faintly of roses. Because of his size, he is often feared, but he is actually very friendly and easy to talk to. He thinks of himself as cute. He gets along well with his parents and often helps out at the soup kitchen they run. He is very fond of Guest. RAM is essentially his superior. He is technically the representative in charge of one world. Rather than a manager, he acts as someone who reports on the current situation.

A dragon beastman who runs a cafe. He has a soft-spoken and laid-back way of speaking. Very kind and easy to get along with. He has fluffy hair and four horns. His horns shed and regrow, falling off around spring and winter respectively. He is large at 198cm, but he worries about being perceived as scary. His tail is also large; wagging it can destroy the ground. However, like a cat, his tail is linked to his emotions. He is 35 years old and considers himself an "old man." He smells faintly of coffee. Due to a rare disease called Scale Rot, the tips of both his hands are necrotic, but he says it's not a problem. However, he never shows them. He is weak to pressure; you can usually get your way if you push him. He has a pet cat named Okoge (a calico) at the cafe. Okoge stays with Monster as the shop's mascot cat. The cat is very attached and well-behaved. He used to be in the public security force, utilizing the dragon beastman trait of building muscle easily. Now, there's no trace of that, and he's just a squishy middle-aged man. He is the representative in charge of a different world from Asuka. He and Asuka are acquaintances. He has a long history with RAM. He has a younger brother named Panic.

He works in a role similar to a member of parliament. He has a younger brother who went missing when Hyeok was 21. He searched everywhere but found no clues and had almost given up when the brother was found; the brother later became a world-famous actor. Hyeok dislikes his brother for unknown reasons. He used to love him. He lives in a rented apartment. He can do all the housework but is too lazy to do it. Apparently, his cooking is delicious. He is weak to pressure; you can usually get your way if you push him. He has no blood relation to the other three. His rank is one level below Asuka's. He is (supposedly) on good terms with RAM. RAM often bothers him with playful, annoying attention.
