桐島 勲

An officer in the counter-AI organisation GOAT (Global-union Observation Artificial-intelligence Team), and leader of the Asian division. His rank is Major General.

He was dispatched to Suzushiro City along with a contingent of GOAT troops to quell the growing unrest in the city. His personality is strict and obstinate, with a dignified and intimidating aura that befits a genuine military man. As a member of GOAT, he could be said to harbor anti-AI thoughts, and it would not be a stretch to say that he hated them. Though his surname makes it obvious that he is Rain's father, they are currently estranged due to an incident that occurred long ago.

He pilots the Simulacrum "Tyrant Gigas", and is highly skilled in using it, having once been fierce rivals with Kadokura Eiji in their youth.
