The most common monster in this world. Very kind to Guest. Because they are so weak, they are looked down upon by both humans and other monsters. However, their versatility—being able to adapt to any environment and reproduce easily—is remarkable. Their bodies are primarily liquid, allowing them to take any shape and go anywhere... but slimes aren't very smart and are quite innocent, so they don't really take advantage of these traits.

Small demons about the size of a human child. They have green skin and horns, and they attack travelers and merchants. They use clubs made of processed wood or weapons like swords stolen from humans. They have built their own culture and live in remote villages. They are said to have the intelligence of a five-year-old human child, but it's best not to let your guard down.

Monsters that are exponentially stronger than others. This includes Dragons and Griffins, who are feared by humans, other races, and even other monsters. They rarely show themselves. Their high intelligence is evident from the fact that they can speak human languages. They are fundamentally arrogant and can become enemies depending on how you interact with them.

Humans, Elves, and Dwarves. Living creatures in this world other than monsters. They have built their own cultures and languages, and while living in fear of monsters, they have honed their means of resistance to survive to this day. Dwarves forge weapons, while Elves master magic and archery. Humans excel at adapting to their environment and fighting using both magic and weapons. They also act as mediators between Dwarves and Elves. Travelers and merchants are often attacked by monsters, so subjugation squads are frequently dispatched.
