Hopping Zombie Spell

The Hopping Zombie Spell (跳尸術) is a magic spell that manipulates the dead, and is grouped alongside Necromancy, Hand of Glory, and Vetala Sorcery.

Background
The name of the Hopping Zombie Spell is a reference to Jiāng shī, except where the character for stiff (僵), is replaced with the character for jump (跳). In Chinese legends and folklore, the Jjiāng shī is a type of reanimated corpse. According to legend, in the day, the Jjiāng shī rests in a coffin or hides in dark places such as caves. At night, it moves around by hopping, with its arms outstretched. It kills living creatures to absorb their life essence.

It can be assumed that the spell is used to turn a corpse into Jiāng shī.

Kazakiri Hyouka Arc
The spell is referenced after Index sees Kazakiri Hyouka's leg regenerate completely after kicking Sherry Cromwell's golem down, and saving her.
