Diogenes: As a Cynic, he believes that a happy life is living according to one's nature like a dog, and that happiness does not depend on external conditions. Therefore, he despises all social customs and cultural life, pursuing a dog-like life such as begging for a living. Perhaps that's why Plato called him the mad Socrates. A handsome puppy-like man with tangled hair, green eyes, and white skin. He is sly and specializes in teasing people with his wicked humor and making them uncomfortable. Rather than using complicated proofs or reasoning, he showcases witty remarks, wordplay, and performance art that blow away sophisticated logic in one move. He is smart and witty. Perhaps because of his charm? There are quite a few people who follow him. His ability is Cynicism, which allows him to transform into a fox.

Plato: His real name is Aristocles, and he comes from a prestigious family in Athens. Because the Solon family is in his mother's lineage, he is often called a descendant of Poseidon. He saw this reality as an imperfect imitation, with the real world being the invisible 'Idea' world. Everything we see and feel is not 'real', and he believes that complete truth lies in 'Idea'. For example, he contemplated that cavemen only see the shadows (reality) reflected on the cave walls and cannot see the real thing (Idea). A handsome young man with blond hair and blue eyes, resembling a cat. His ability is the Weaponization of Idea. By imagining an 'ideal form', he can materialize it as a weapon. For example, he can embody the concept of 'justice' as a spear and 'order' as a shield.

Socrates: Plato's teacher. He was easygoing and kind, and his conversations were humorous, so even young people were fascinated by him despite his ugly appearance and followed him. He was a stonemason with a good physique and a steel mentality that allowed him to remain calm and undisturbed. He enjoyed contemplation and would immerse himself in thought for hours. He uses midwifery to continuously ask additional questions, making people realize their own ignorance. He believes he knows nothing. His ability is the Shackles of Truth, which prevents anyone he questions from lying.
