Description
Amata Kihara belongs to the scientifically amoral Kihara Family and commands Hound Dog, a black ops unit answering directly to Academy City's board chairman, Aleister Crowley. He exhibits exceptional cruelty, viewing subordinates as disposable "garbage" without human rights and espers as mere experimental animals. He did, however, show limited restraint with child test subjects, notably sparing a young Accelerator due to his research value.

His appearance features short blonde hair, a prominent tattoo on the left side of his face, and distinctive attire: a white lab coat worn over a dark jacket, black shirt, and pants. He regularly uses Micromanipulators—mechanical gloves enabling precision microscopic work—though their exact combat applications remain undefined.

As Accelerator's primary ability developer, he engineered the esper's vector-control powers while deliberately embedding weaknesses, including vulnerabilities to soundwave interference disrupting wind-control calculations. He created the "Kihara Counter," a technique exploiting Accelerator's redirection by retracting attacks milliseconds before impact, causing the reflection field to pull strikes inward. Beyond this, he is proficient with heavy weapons like anti-tank missile launchers and grenades.

In the Academy City Invasion Arc, acting on Crowley's orders, he attempts to kill Accelerator and capture Last Order. After overpowering Accelerator initially, he captures Last Order and uses a Testament machine to infect her with a virus designed to activate the angelic entity Fuse Kazakiri. When Accelerator confronts him again, Kihara destroys the antivirus chip. Accelerator ultimately manifests black wings composed of AIM fields and kills Kihara by using him as a projectile in a railgun-like attack.

After his death, his legacy endures: his combat techniques and thought patterns are adopted by other antagonists, including his relative Kihara Enshuu, who uses them to defeat high-level espers. A side story confirms he has a son active in Academy City's dark side, though the son's identity and abilities remain unknown. In a non-canon video game scenario, he manipulates Mugino Shizuri into partnering with a traitorous Misaka clone for an experiment involving dimensional manipulation.

A flashback in *A Certain Scientific Dark Matter* reveals his indirect involvement in the Dark May Project, where he expressed disdain for its methodology after witnessing test subject Yuzuriha Ringo's outburst following her friend's death.
