Four Yin Demonic Beheading Sword
The Four Yin Demonic Beheading Sword is a Gwanghwamun hidden-piece sword whose defining function is cutting the bond between constellation and incarnation.
History
Hidden beneath Gwanghwamun
Han Sooyoung collects all seven star jewels, summons the hidden piece, and becomes its first scenario-era master. Kim Dokja takes the sword after defeating her and uses it to sever the Absolute Throne's constellation-level connection. (Chapters 62–72)
Severing sponsor bonds
The sword later opens its power against Yoo Joonghyuk's sponsor connection and a world-line counterpart is empowered through Kim Dokja's constellation support. These uses preserve its original specialty rather than turning it into a generic stronger blade. (Chapters 151, 295, and 523)
Abilities and properties
- Its special effect cuts or interferes with links between constellations, incarnations, and scenario authority. (Chapters 71–72 and 295)
- Its value is situational: it is decisive against bonds and contracts, not automatically superior in ordinary sword combat. (Chapters 62–72)
