Sylph Bell

Sylph Bell (の鐘) is a technique used by Lewin Light.

Description
Summoning a Sylph, Lewin uses it to mark a target so their rough whereabouts will always be known to him. This is first shown when he marks Renzo Shima so that he might be able to get a rough location on the Illuminati's hideout.

Used in conjunction with a Ouija Globe, the target can be tracked very precisely, even across several countries.

If the target tries to remove the Sylph Bell, a curse of beheading activates, but this can be diverted to another part of the body.
