Kakine Teitoku

Kakine Teitoku (垣根 帝督) is one of the seven Level 5 espers, ranking second after Accelerator and is the leader of SCHOOL, one of the many underground factions.

Personality
He shares a rivalry with Mugino Shizuri, team leader of ITEM and Level 5 esper. He strives to become the strongest, even if it means to kill off Accelerator. He's also a ruthless, cocky, and cold hearted individual who shows no mercy or compassion towards his enemies or bystanders and won't hesitate to look down on anyone whom he deems inferior. The perfect example of this is when attempting to find Last Order to draw out Accelerator he attacks and tortures Uiharu and was on the verge of killing her when she refused to get him Last Order's location.

Plot (Toaru Majutsu no Index)
He was the "spare plan" for Aleister Crowley's secret project in the event that Accelerator would not meet Crowley's expectations. He did not like the idea and tried to eliminate Accelerator but failed.

Later, he learns the true capability of his power and "awakens", after which he gains three pairs of wings (like a seraph) and acquires flight capabilities and greater proficiency with his manipulation of Dark Matter. He is able to corner Accelerator, but Accelerator manages to update his AIM field and add Dark Matter to the list of things he can control. Accelerator then proceeds to hold an advantage even using Dark Matter against Kakine. Accelerator then also "awakens" and finally defeats him, destroying most of his body. Later is revealed that his hatred and envy towards Accelerator was set to make him to fight Accelerator and help Accelerator to growth.

He is currently being kept alive by "Dark Legacy", where his brain is preserved as a constant source of Dark Matter.

Abilities
The angelic nature of his ability is described as "He who wields a piece of the Heaven that is inhabited by God", and just like Accelerator, Aiwass has shown great interest in the now torn apart body of Kakine.


 * Dark Matter (未元物質), is his esper ability which allows him to create an unknown material that he uses to attack. It should be noted that the term "Dark Matter" is not to be confused with the true "Dark Matter" which is among the components of the universe. In addition, 'unknown matter' here does not mean matter that has not been discovered by humans but matter that did not exist until it was created by Kakine. The material he creates defies the Laws of Physics. His Dark Matter can even strike Accelerator with his power of Redirection, though after Accelerator taken into account 'normal' physics don't work on Kakine's ability he re-calculated and managed to reflect Kakine's Dark Matter later. During his fight after watching Accelerator's 'Awakening' he learned the real nature of his own powers and the origin of them noticing that they came from another dimensional plane and then his wings growth to a size of about 30m, but just before he could use his recently understood powers he got defeated by Accelerator.


 * Pincet Glove: Is the claw that Kakine wears on his right hand, it is the tool he uses to to grab nano sized matter. Kakine used it to capture Underline, the nano-machine which Crowley used to monitor Academy City.
