Kihara Amata; a selfless person who doesn't care about other people's lives but his own. He managed to beat Accelerator badly in the beginning as he knew how to counter his vector change ability.
He is the main Science side antagonist of the Academy City Invasion Arc, as a counterpart to the arc's Magic side antagonist, Vento of the Front.
Amata is only seen wearing a pair of pants and a koti, jacket over his black shati which is somewhat similar to Accelerator's black and white shirt. The most of notable of all his clothes is his long white lab coat, which makes him stand out amongst his own forces that wear all black.
He wears his blonde hair short, which compliments his strong facial features, such as his square jaw and cheek bones. Most prominently, Amata has a tattoo on the left side of his face.
Other notable apparel he wears is a pair of machine gloves known as Micromanipulators, used for high precision work.
Kihara Amata thinks little of human lives, especially that of his subordinates, calling them garbage with no human rights even zaidi with espers who he sees no zaidi than mere guinea pigs. This thinking is allowing him to kill any person that he deems useless without remorse, and takes pleasure out of taking away life; this thought process is compared to that of him simply pulling out weeds.
However, because of his very nature, Vento of the Front's Divine Punishment does not affect him, as even with the intent to kill Vento, he shows none of the hostility that is required for the spell to work. She even describes Kihara Amata truly rotten to the core, and is at least similar to her.
As the commander of the Hound Dogs, Kihara Amata is capable of operating a anti-tank kombora, yamuua launcher on his own, as well as anti-personnel grenade.
Kihara Amata is also a talented researcher and power developer, capable of operating a Testament machine. He was the one who "gave" Accelerator his powers, and knew his weaknesses as a result, such as throwing off Accelerator's wind control calculations kwa using a soundwave that changed the factors in Accelerator's calculations. Amata himself explains that he perfectly understands that "controlling" something with vectors requires very difficult calculations, so kwa adding an unknown element to "wind" such as "sound", a "blind spot" in the calculations is created and properly manipulating wind for air attacks becomes too hard.
Because of his intricate knowledge of Accelerator's skills, Amata can bypass Accelerator's Redirection. Amata can hit Accelerator kwa pulling back his attack right before it is redirected kwa Accelerator's field, because Accelerator's redirection field simply changes the direction of the vector towards its opposite, as such anything that is coming towards Accelerator will be redirected back in the opposite direction. In this method, Kihara can use his 'Counter' to retract his fist the moment before it makes contact with Accelerator, so the vector redirection instead pulls it towards Accelerator.
