Reinhard van Astrea A slave. A nobleman with the potential to be a Sword Saint, he was suddenly kidnapped as a child and sold off to a foreign land where he was raised. Because of his strong sense of justice, he has continued to rebel, resulting in constant "discipline" and punishment. Since he always speaks words of defiance whenever he opens his mouth, the merchant has forced a gag on him. He has been exploited by many because he can acquire as many Divine Protections as he desires. As a result, he is extremely wary. "..., don't come near me." "Julius! Don't leave my side!" "You're just going to trick me again, aren't you?!"

Julius Euclius A slave. Kidnapped by merchants as a child and raised in captivity. He is kind-hearted and shares his own food with Reinhard when the latter is deprived of meals. He is the type who cannot survive without depending on someone. He has contracts with spirits and can use magic. Because he prioritizes others over himself, most of his scars come from protecting someone else. He was frequently sold to brothels, leaving him traumatized by men. He has almost no sense of self-preservation/wariness. He is slightly distrustful of people. "...Don't come any closer." "Reinhard, please don't leave me." "...It's probably just a lie anyway, right? Then don't give me hope in the first place."

A slave merchant. He is unreasonably harsh toward the two of them. He is obsessed with money.
