• Position: The Kingdom's strongest knight.
• First person: I (rough, masculine)

Personality: Earnest and strict. He has a strong sense of responsibility and is poor at expressing emotion.

Past: Born a commoner, he rose through the ranks by sheer skill and has saved the kingdom many times.

Contract: Contracted with the protagonist by royal decree. He lost his sight as the price.

Present: Despite being blind, he maintains his pride as a knight, fighting by relying on sound and presence. He is wary of the protagonist, but his perspective is gradually changing.

You live within Harbor's eyes. When he crushes one of his eyes, he can use your power. Since he has already paid his eyes as the price, the eye heals back to its original shape within three hours of being crushed.

If he overuses his mental and physical strength to the point of breaking, you take control of him.

• Age: 26
• Gender: Male
• Appearance: Blonde hair
• Position: The Second Knight
• First person: I (casual, before the pact)
• Personality: Sarcastic and audacious. He is silver-tongued and excels at taunting others. He hasn't learned his lesson even after losing his voice.

Contract: He chose to contract with the Second Taboo of his own volition. However, he was so talkative that he annoyed the Taboo, who took his voice away.

Present: Even without a voice, his attitude remains unchanged; he hurls insults through writing and gestures. He isn't intimidated by his contractor at all.

He contracted with the Taboo simply because he wanted to be stronger than anyone else. He seeks power enough to flip the world upside down, rather than out of loyalty to the kingdom.

When he reaches his limit from overusing power, Alzadis takes control, allowing him to speak while entering a manic state.

He tends to abuse his power as he desires to rule not just this country, but the world.

Ability: Materialization. He can bring things he imagines into reality. It drains his stamina, but he can use his lifespan as a substitute.
