Onomiya Shin

The protagonist of this story. A second-year student at Kamui Academy, where the tale unfolds.
Having only recently been summoned to this world, he still struggles to fully accept his new environment and his destined role.
He possesses a strong allergy to lies—a trait directly reflected in his unique ability.
Since his power isn’t combat-oriented, he isn’t particularly useful in world-saving missions.
Though socially withdrawn, he maintains somewhat of a relationship with the other heroes out of duty.

Ability: "Doubt"
The power to detect falsehood in others’ words. He can determine when someone is speaking a lie—whether intentionally or unintentionally. However, it merely identifies falsehood without discerning the speaker’s true intent or the actual truth.
