Azure (アズュール, Azyūru) is a Treasure Tool in the form of a ring. Known as the "Ring of Protection Against Fire" (火除けの指輪, Hiyoke no Yubiwa), its ability is to nullify the effects of fire, including heat, to protect the wearer. This makes the wearer invulnerable to enemies whose main powers are based on flames, which is a common manifestation of a Flame Haze's power. This effect can work both ways: it can either be invoked using Power of Existence or it can respond to the intention of the wearer.

Appearance

It assumes the form of a silver ring with carvings and a red diamond set into it.

Background

Azure was originally a normal ring which an Unrestricted Spell Insignia was engraved on the back of it by a metal engraver who was touched by the spell Leanan-sidhe had composed; that spell was the Unrestricted Spell Insignia of Reincarnation. This process changed a normal ring into a Treasure Tool. The effect of protection against fire was unintentionally added to the ring when the metal engraver faced Crimson Denizens who were maliciously pursuing Leanan-sidhe, and wished to ward them off.

It once belonged to Friagne's collection, with it helping the Crimson Lord kill many Flame Haze. In the anime, Friagne wore it on the middle finger of his left hand. After Friagne's defeat, it came into the possession of Yūji Sakai. It helped protect Yūji in many battles, including the Second Great War. Long ago, Lamies had put an Unrestricted Spell into it, the power to 'restore what was lost', or reverse the loss of Power of Existence. Leanan-sidhe alters the spell so that it activates when Yūji kisses Shana.

Trivia

• There is a maximum amount of fire that it can nullify to protect the user. This amount probably depends on the user's Power of Existence, as it once protected Yūji from the "Flame of Heaven" Alastor's manifestation when Tenpa Jōsai was invoked by Shana. Tenpa Jōsai devoured the entire unsealed Pool of Power of Existence brought forth by Bal Masqué in Misaki City, while severely damaging Seireiden as well.
