Tatara

Tatara (鈩) is an exorcist and Tōda (騰蛇) of the Twelve Guardians.

In the anime, he is revealed to be a Shikigami.

Appearance
Tatara appears to be wearing a male priest uniform. He has a paper mask that covers his face, Tatara's mood is reflected on the paper that covers his face. He also holds a bag of bread crumbs that he eats out of fairly often.

He has cracks under his eyes, similar to scales on a snake, either due to his snake related powers or his injuries in the battle in his first hometown, the Kingdom of Noto. After being brought back to life his size has decreased so that he's now as small as Kinako.

Personality
Tatara is considered the most sinister of the Twelve Guardians but is generally calm as long as you do not break any rules.

He does have a justified reaction when displeased, such as when he shows a brief flash of his power after an Impurity slashes his bag of bread crumbs.

Plot
Tatara shows up behind Rokuro Enmado and Kinako to scare off Itsuki Zeze and other members of the Zeze House, who are attempting to repossess the Adashino House's land.

In the anime, he fought Kuranashi without restraint, not just to avenge the deaths of the Twelve Guardians and protect the Twin Stars, but also to make Kuranashi pay for the massacre on his hometown 600 years ago, the Kingdom of Noto. As mentioned by Seigen Amawaka, Kuranashi used his spell power to make seven villages of the kingdom ascend to the sky, and used his army of Impurities to slaughter all the people on the floating islands. Tatara might be the sole survivor of the Noto Tragedy.

Powers and Abilities
Not much is known about Tatara's powers other than him being the "most destructive" and "most sinister" of the Twelve Guardians.

Tatara is shown to be wild and chaotic, and evidently very powerful, as he was able to go up against Kuranashi who had absorbed the powers of the Twelve Guardians, although it should be noted that the absorbed Guardians were greatly weakened thus it can be assumed Kuranashi didn't manage to gain that too much power.

Tatara releases his power by using Phantom Serpent Coil, with hidden marks on his forehead and chest glowing as a sign of its awakening. His divine enchantment is Toda Crystal Talisman.

Subaru Mitejima
Tatara is usually seen with Subaru, another Guardian and Benio's mentor in the anime.

Kuranashi
Tatara has been holding a grudge against Kuranashi for more than 600 years.

Trivia
