Theoretically, the position of total governor of Heijian Star is now under the control of Gu Hang.
The current 'governor' is Nes Luman, and this King is indeed under the control of Gu Hang. Not only is his mind controlled by Gu Hang, but the military, political, and economic aspects of the country are also under the alliance's control.
However, this type of control does not represent the alliance's control over the entire Heijian Star.
The position of Nes Luman as governor comes from the special political ecosystem of Heijian Star: the King's Council.
Those elected by the King's Council will temporarily hold the position of governor of Heijian Star until the next election.
After the last session of the King's Council, the Luman Kingdom, which had chosen the wrong side during the previous war and was beaten by the military of Rage Owl Star, rightfully lost its seat as governor.
