The [[Vessel of Sin|Vessel of Envy]], inhabited by the demon [spoilers][[Rahab Barisol]][/spoilers]. 

Originally a pair of ceremonial blades belonging to the former Kingdom of Levianta, they were sent to the Eastern country of Jakoku and reforged into a pair of scissors, one Western looking and the other [[clippers|Eastern alike]] to conceal their identity. Eventually these were inherited to the hands of [[Sudou Kayo]] who used them for her infamous killing spree in Enbizaka.
