Ley Batenkaitos

Ley Batenkaitos (aka: Sin Archbishop of Gluttony) is an antagonist in the Re: Zero series. Ley is a member of the Witch Cult. He makes his first appearance in the Re: Zero Interlude (between Arc's 3 & 4) and is responsible for raising the White Whale, as well as erasing Rem's entire existence.

Appearance
Ley is a short boy with long dark-brown hair. His attire consists of a dirty rag-like piece of cloth around his slender body. Undeneath his rag-like outfit appears to be wounds from whip mark and bite marks.

Personality
Like his aforementioned Sin, Ley prioritizes on what he eats (like Roy Alphard), but doesn't emphasizes on what he eats (like Louis Arneb). He and other Gluttony Sin Archbishops speak in a collective manner using we and us, rather than speaking in first or third person.

He also resents merchants, believing that they're only interested in lining their pockets, as well as choose to weigh a person's value and opinion before calculating.

Ley also appears to be rather calm after learning that his pet the White Whale is killed, simply remarking that he can just raise another one in its place.

History
Ley and Regulus first appeared in the Interlude Chapter of Re: Zero. He and Greed decimate Crusch's forces and specifically devours Rem's memories and existencce, putting the Oni maid in a suspended animation.

powers and Abilites
Being the Sin Archbishop, Ley is shown to be powerful to the point that he made short work of the majority of Crusch's army. The special ability: Authority of Gluttony allows him to eat a person's memories, which renders the victim in a comatose state (being unable to eat, breathe, exctrete bodily functions).

Ley has a trump card ability called Eclipse, where his madness and resentment is amplified to a sinister level and can move at instantaneous speeds (according to Otto Suwen). He has two variation which were never explored, the Solar Eclipse and Lunar Eclipse.
