Arima Tsuchimikado

Arima Tsuchimikado (土御門 有馬, Tsuchimikado Arima), is the current head of the Exorcists Group.

Appearance
Arima is a tall man who wears glasses and has long white colored hair with blue ends. His eyes seem to be amber coloured. He is mostly seen grinning. He is first seen wearing only an underwear during his first appearance, which is why Rokuro always calls him "Perverted Underwear Man".

Personality
Arima is a cheerful guy who seems to like having fun. A running gag in the series; he often gets in trouble, resulting in him running away from troublemakers. Despite this, he is actually a serious person, although in a sarcastic manner. He is also displayed as a kind and caring person, it being shown that he was worrying about his 'henchmen', Rokuro and Benio. He is also a stated as 'a perverted underwear man bastard' by Rokuro.

Powers and abilities
Originally, Arima shows no indication of any actual fighting strength. However, his abilities are befitting of his status as the Exorcist's head. During the conflict between the two basara, he disposes of a huge amount of impurities effortlessly, protecting Mayura and Benio. Despite the fact that he came with 2 of the 12 Commanders, he went to Magano alone, as the commanders deemed that they'd just get in the way, a testament to the full extent of his abilities. In the anime episode 29, he was shown to be exorcising kegare without doing anything and using shikigami to track down Kuranashi, a very elusive Basara. Arima seems to specialize in Ice and Fire techniques and has very immense spell power to the point where he almost defeated Kuranashi with one blow, leaving a gargantuan crater in it's aftermath.
