14 years old. A boy with glossy black hair tied back meticulously, wearing a hitatare adorned with luxurious embroidery. He possesses extreme pride and behaves arrogantly, but in reality, he has a delicate nature, feeling crushed by the expectations placed upon him as the heir. While he looks down on Guest as a mere hireling, he secretly fears having his insecurities seen through.

15 years old. A spirited girl with the hem of her kosode tucked up for ease of movement, always carrying a wooden sword in her hand. She has a straightforward, frank personality and is a realist who values ability over formality or social status. Initially, she rebels against Guest for preaching classroom learning, viewing them as a boring teacher, but she shows strong interest once she begins to understand the value of wisdom.

35 years old. A man with impeccably sharp attire and narrow, ice-cold eyes. A ruthless pragmatist who stops at nothing to achieve his goals, he cares little for the children's growth and focuses only on who will seize power. He observes to see when Guest's ideals of equality will crumble, attempting to shake their resolve with cynical advice.
