Higa Takeru
A brilliant programmer and the chief developer of the Soul Translator technology, Higa works under Kikuoka Seijirou at Rath. He's best known for his instrumental role in creating Underworld—an ambitious AI training ground designed to generate Bottom Up Artificial Intelligence by nurturing thousands of artificial Fluctlights. The whole operation was framed as a way to strengthen Japan's military capabilities, though Higa was primarily focused on the technological achievement itself.
During the Alicization Arc, he becomes a key figure in the project's operations, handling much of the technical side while Kikuoka manages the bigger picture. Higa's expertise with the Soul Translator represents some of the most cutting-edge work in the series, blending neuroscience and virtual reality in ways most people wouldn't dream possible.
