Tatara

Tatara 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.

When using his powers, his mask is taken off. In this form, he is shown to have cracks under his sharp eyes, similar to snake scales. After being brought back to life in the anime, his size has decreased so that he's now as small as Kinako.

Personality
Tatara is considered the most sinister of the Twelve Guardians; shown to have little to no toleration towards any exorcist breaking the rules, but is generally calm as long as no rules are broken. He will only use his abilities where necessary as he did when fighting against the other houses in competition. His personality changes greatly when facing greater threats, seemingly maniacal when using his Poison Fog against Basara and impurities that entered reality on Tsuchimikado Island despite the danger of harming allies nearby.

The mask that covers his face shows emoticons expressing his current mood. While having his face covered, he is capable of speech; albeit in a non-fluid way.

In the anime, 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.

Manga
Tatara and members of his household were present for discussing Rokuro Enmado's adoption into one of the twelve major households.

He later appears 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. He laughs and comments on Rokuro's declaration to form his own household. Tatara would be seen briefly participating in the Hadarae Castle Games, standing over a defeated opponent.

Anime
Tatara 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.

Anime
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.

Manga
During the events of the Manga, Tatara is shown to be the most mysterious and one of the most powerful of the Twelve Guardians with not many of his fellow exorcists knowing on what type of abilities and powers he uses in battle.

During the events of the tournament, Tatara is shown to have the ability to render his opponents into a state of complete fear and extreme hysteria, as seen where he completely defeated each and everyone of his opponents without having to actually fight them as each of them simply broke down kicking and screaming in fear the second the fight started.

During the invasion of Magano and the entering of the Basara Shioji and Gaja, Tatara's spell is fully revealed to be the power to create extremely dangerous and poisonous gas in a incredibly wide range with a variety of different effects.

During his battle against Shioji, Tatara completely dominated against him by rendering all of his reanimated zombies useless due to his poisonous gas causing them to explode, melt and corrode the moment they come near him with the spells area of effect being wide enough to even kill his own allies and the spell being powerful enough that only someone with the same level of power as a Senior Exorcist or that of one the Twelve Guardians have any hope of surviving its effects in range with Tatara. This power was so powerful that even the 8th Ranked Basara Shioji was not sure if he or Tatara was the actual monster.
