Cheon Yo-hwa's Black Hair Tie

Cheon Yo-hwa's Black Hair Tie is a small memento left in the Undertaker's hand when Cheon Yo-hwa disappears while guiding him through the unconscious world.

History

An anchor in Hecate's world

Yo-hwa's disappearance leaves the tie as physical evidence of their connection in a reality built from suppressed memory and anomalous identity. Go Yuri recognizes it as a ghostly treasure, and the Undertaker uses it to resist mental interference while pursuing the truth beneath Hecate's form. Its value comes from a remembered person and promise, not an ornate design or conventional enchantment. (Chapters 365–367)

Lost with the corrected reality

When the unconscious world's contradictions settle into the 999th cycle, the hair tie can no longer remain as an object made under the earlier rules. It vanishes rather than transferring into ordinary custody, ending its protective function while leaving the relationship and information it anchored intact. (Chapter 372)

Abilities and properties

• Anchors memory and identity strongly enough to help resist brainwashing in the unconscious world. (Chapters 365–367)
• Exists only under the anomalous reality that produced it and disappears when that reality resolves. (Chapter 372)
