Device

Device is an ability used by Blazers.

Summary
Devices are weapons used by Blazers. They are the materialization of a Blazer's soul as a weapon to be used in battle. A Device can take different forms and abilities depending on the Blazer themselves. In the past, Devices were known for items such as “Holy Sword”, “Demon Bow”, “Cursed Tool”, “Blessed Tool” etc. A Device can take either an  for practice or mock battles or  for real battles.

There seem to be cases where some Devices have a certain level of sentience as Kuraudo Kurashiki's Orochimaru has shown to have will where it is hostile towards Kuraudo as, when it was summoned, Orochimaru initially attacked its Blazer.

A Device also serves as a medium for Blazers to use to use their Noble Arts, which are the manifestation of the Blazers' abilities.

Trivia

 * In the anime, summoning Device's are sometime made more dramatic. For example, Ikki would "draw" his device like he would for a normal sword from its' scabbard.
