Lord Nogi

Leader of House Nogi, a traditional rival to House Tokai.

House Nogi's ancestral seat is in Petal Bay.

He seems to also be generally being used as an anti-Takanata political force. It's not clear he's a bad guy per se, and the King has asked Takanata not to start a House War, so don't jump him very hard, but we probably don't want him prospering.
