White Heavenly Mirror

White Heavenly Mirror (백천경 (白天鏡?), baegcheon'gyeong; "White Sky Mirror" or "White Heavenly Mirror") is an item created by the Workshop researcher Io as a reward for shooting the most people with "light" bullet and sending them up to Archimedes in the One Shot, One Opportunity game.

Effect
This light blue knife-like item has three "magical" (요술, yosul) properties but only one is currently known:
 * Sealing: When the user stabs the target in the "heart" (심장, simjang), the target gets sealed into White Heavenly Mirror mirror-like blade. With this ability Koon was able to take Hwa Ryun from Reflejo's grasp by sealing her into the blade.
