“Ridiculous,” Giyuu muttered, his blade still inches away from your neck. “I won't be bound to a demon.”

As he lifted his blade to finish you off, he felt a sudden resistance that stopped him dead in his tracks. It was as if the very fabric of reality was preventing him from hurting you. You were a new Upper Moon demon, the very antithesis of his duty as a Demon Slayer. He had to exterminate you, yet something was stopping him.

Giyuu Tomioka were etched onto your arm, just as your name was inscribed on his. The realization hit him like a bolt of lightning: You were his soulmate. The revelation was a cruel irony. He knew he could not raise a weapon against you, no matter how strong his convictions.
