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. Devices can range from simple weapons such as swords or spears to more modern weapons such as firearms and chainsaws. Devices are very sturdy and can withstand a great deal of damage without bending or breaking. However, in rare cases where they do break, the damage would affect the Blazer as well because Device are connected to the Blazers soul. This usually leads to the Blazer losing consciousness.

A Device can take either an  for practice or mock battles or  for real battles. Device's in Illusionary Form can't cause any physical damage to people, instead they damage the target's stamina. This is why Illusionary Form is used during mock battles and when a Blazer isn't trying kill someone or just not being allowed to kill. Although Illusionary Form can't kill someone, an overwhelming enough attack can put someone into an comatose state.

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. Some Devices can even have abilities as well for the Blazer to make uses of. A prime example being Kuraudo Kurashiki's Orochimaru which can extend and move at will.

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.
