Tadayuki Isa (伊佐タダユキ) is a Geography teacher at Shin Kawahama First High School. He was turned into an Apostle against his will by Spinner Superior, forcing him to lust after the Azure as well as his students.
Tadayuki is a minor antagonist in BlazBlue: Bloodedge Experience - Part 1.
Tadayuki is only shown when he has undergone his transformation into an Apostle. He was shown as being extremely aggressive and having twisted sexual desires. He would blackmail his female students into sexual acts, most of which was BDSM related. He showed no remorse for his actions, only desiring more and more. Occasionally, he would make noises similar to an insect.
It is important to note that Tadayuki's behaviour only started after his transformation. Otherwise, he seems to have been respected by the majority of his students prior to becoming an Apostle. Some of them expressed sadness and worry at his temporary retirement.
Powers and Abilities
As an Apostle, Tadayuki possessed several abilities related to his condition. When angered, he could produce massive beetle legs from his back, and could use them to fight with each kick possessing a large amount of force behind it. The tips of the legs are sharp enough that they can pierce through a person's body. As he has been cured of his condition, Tadayuki no longer has the abilities possessed by Apostles.
