Madou Bell

Madou Bell (魔導ベル) is a bell-shaped Madou Tool carried by the Makai Knights and Makai Priests in GARO: Honoo no Kokuin.

Functionality
Madou Bell is commonly used to detect Horrors by holding it in front of the target and ringing it. The vibrations from the ring pinpoint a Horror's location in a crowded area, causing the eyes of the detected human host to glow red, sometimes forcing it to assume its true form.

In the movie, as in the TV series, Madou Characters also can appear in the eyes of the detected person.
