Yukihira Togashi

From the XSIII Database Transcription:

Researcher at the KOS-MOS Project General Operations Systems Development Lab. His hobby is judo.

He entered Vector First R&D Division immediately after the incident in which KOS-MOS went out of control.

Though in love with his co-worker Miyuki, she transferred to the Second R&D Division before he had made a move; his sensitive soul, at odds with his appearance, was left holding the pain of unrequited love.

Partially in hopes of distracting himself from his hurt feelings, he makes teasing Allen, the new Chief, a crucial part of his daily routine.
