Twin Blades of Levianta

The Twin Blades of Levianta was one of the vessels of sin, inhabited by the Demon of Envy. Kayo Sudou was among its most prominent owners, infamous for causing the Enbizaka Murders.

Creation
At some point, a pair of dual blades were forged. After the original vessels of sin were released into the world by Hänsel and Gretel in EC 014, the Demon of Envy eventually inhabited the twin swords as its vessel. At some point, the blades ended up in the possession of the Levin Church in Divine Levianta.

New Four Horsemen
In EC 508, Abyss I.R. acquired the Twin Swords of Levianta and used them to have the high-ranking Levin Church member, Mikhail Asayev, become possessed by the Demon of Envy, collaborating with him. Envious of his his fellow constituents climbing the ranks, Mikhail contacted radical hardliners within the Church and the four formed Neo Apocalypse, launching terrorist attacks across Levianta.

After Abyss I.R. was injured and forced to flee and Neo Apocalypse was put down, the Demon of Envy returned to its vessel and the twin blades were obtained by Chartette Langley. The women then traveled to Jakoku in the far Eastern region and reforged the swords into two pairs of scissors of two distinct styles. In EC 549, Chartette gave the vessel to a purple-haired soldier outside Enbizaka.

Enbizaka Murders
The vessel was later acquired by a Kagura Sudou and eventually passed into her daughter Kayo's possession. In EC 842, Elluka Clockworker encountered Kayo and swapped bodies with her, replacing one of the scissors with a fake pair. Around this time, Kayo became possessed by the Demon of Envy. Envious that her "husband" appeared to be cheating on her with three other women in Enbizaka, Kayo killed each of them with the vessel before killing the man.

Slumber
The scissors were later collected by Gallerian Marlon and stored within Evil's Theater around EC 982; around that time, both scissors were strung together. After the destruction of the Third Period in EC 998, Michaela summoned all seven vessels together for Allen Avadonia. The Demon of Envy later manifested her form and took the scissors with her to Toragay to meet with the boy before taking him to Jakoku.

Mechanics
Similar to the other vessels of sin, Kayo's Scissors served as containers for the Demon of Envy's essence and allowed the demon to possess or influence a host. From the scissors, the demon would be able to fuel its owner's jealousy, turning it into envy. Like the other vessels, the empty scissors could be inhabited by another Demon, although a skilled individual must purposefully move them. The Demon of Envy could also presumably travel between the two pairs of scissors. As the demon was the source for Kayo's Scissors' power, sealing the vessel subsequently suppressed the demon and left the object powerless. The blades neither dirtied nor rusted, allowing them to consistently stay clean and usable for their owner; this also made them excellent weapons, keeping the twin swords and later the scissors sharp and never degrading.

Conceptualization and Origin

 * The vessel's representative sin is derived from Envy of the Seven Deadly Sins.
 * The Sin's depiction in Chrono Story as a body of water may be reference to Leviathan, the patron demon of Envy; the Leviathan is commonly depicted as a giant sea monster.
 * The name of its vessel, the Twin Swords of Levianta, is also likely a reference to the Leviathan; the state of Levianta also derives its name from the demon.
 * Scissors can symbolize the separation of a couple, cutting away something that doesn't benefit you anymore, and the fear of being cut off from someone you love.
