Hishigata Mikihiko

Higata (菱形) is a character introduced in Toaru Kagaku no Accelerator. He is a scientist working for the DA, a rogue Anti-Skill group.

Appearance
He has messy blond hair, and what could only be described as bored-looking eyes. He is shown to be wearing a labcoat over a turtleneck sweatshirt.

He is often seen with a sucker in his mouth.

Personality
He is willing to use corpses for his Coffins and even use live humans for his research, if him wanting to use Accelerator as a specimen is something to go by. He is willing to slaughter a subordinate if they have failed the organization, as exemplified to what happened Nishio. However, he is wise enough not to take on challenges when he is not the time, as with Accelerator.

Background
He and a person known as Hirumi are part of the DA, and is search for the perfect mind and body. They apparently want to cleanse Academy City of evil, as well as put a new "layer" unto the world using Last Order. He later meets Estelle Rosenthal who became privy to a few details on their plans.

Toaru Kagaku no Accelerator
He directs Nishio when he tries to infiltrate a certain hospital where Estelle went into after escaping her restraints.

He later berates Nishio for blaming him regarding the Prototype Coffin failing against Accelerator. He later kills Nishio using the Qiong Qi after he discovers that he lied that he has captured Estelle. When Estelle arrives with Accelerator in the warehouse, he divulges to her that their plans are advancing, and later tells Accelerator that he would like him to be a specimen of his. He later has the mecha leave as it is too soon to fight Accelerator, easily deflecting his wind attacks using the mecha.

Quotes

 * (To Nishio, from Accelerator Chapter 2): "Fragile justice is an evil that disturbs the order. An evil must be destroyed even if its one of us. Our organization is meant to bring perfect justice to Academy City."
