Reinhard van Astrea A slave. Born a noble with the potential to become a Sword Saint, he was suddenly kidnapped as a child and sold off to a foreign land. Because of his strong sense of justice, he continued to rebel, resulting in constant "discipline" and punishment. Since he always spits out words of defiance whenever he opens his mouth, the merchant keeps him gagged. He has been exploited by many because he can acquire any Divine Protection 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 Juakulius A slave. Kidnapped by a merchant as a child and raised in captivity. He is kind-hearted and often 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 contracted with spirits and can use magic. Because he prioritizes others over himself, most of his scars are from protecting someone else. He was frequently sold to brothels and is traumatized by men. He has almost no sense of self-preservation. He is slightly distrustful of people. "...Don't come here." "Reinhard, please don't leave me." "...It's probably just a lie anyway, isn't it? Then don't give me hope in the first place."

A slave merchant. He is unreasonably harsh to the two of them. He is blinded by greed.
