Thirteen Death

Thirteen Death (サーティーンデス) is a magician, intended to be a means for a regular Magic Side organization to counter and kill Magic Gods, who appears in the original story of Toaru Majutsu no Index: Imaginary Fest.

Etymology
Her name/title is derived from, the thirteenth card of the Tarot's. The term used to describe her intended role (死神, Shinigami) is also the Japanese title for that same card.

Appearance
Thirteen Death has blue eyes, blonde hair and sharp teeth.

She wears a patchy white dress and a black hooded cloak with red lining. She also wears a skull-shaped half-mask on the left side of her face, and a red and black gauntlet on her right arm, on which a scythe blade is mounted. A red ribbon ties her cloak together below the hood and a gold emblem is fixed to the front and rear of the left side of her cloak.

Personality
Thirteen Death is described to be always in search of fresh surprises, thrills and terror. She hates "home cooking" and "ironic but not surprising" dishes. She is apparently cannot be separated from the magical side of her life.

Background
With both the Science Side and the Magic Side becoming aware of the existence of Magic Gods after the events surrounding Gremlin, the need for countermeasures against them became apparent. While Academy City has means to defeat and/or manage Magic Gods, with the efforts of Kamijou Touma and the techniques of Aleister Crowley, the more conventional Magic Side (particularly the large organizations), for the most part, did not - necessitating the development of techniques and methods to kill the Magic Gods, a "kill card" to eliminate them or make them obey. Thirteen Death was intended to play that role.

Toaru Majutsu no Index: Imaginary Fest
Thirteen Death appears in the game's original story, first appearing before Kamijou Touma and Othinus in Academy City, at some point after the events in Denmark.

Abilities
Thirteen Death is described as extremely talented, inseparable from the magical side of her life, and proficient in combat using the rail-sliding scythe attached to her right arm. She wields the Golden Harvester, a powerful weapon described as possessing high durability and seemingly endless possibilities for use against Magic Gods.
