I'm looking for anime or manga with a very powerful MC who is surrounded by loyal and powerful followers/servants.

I'm especially looking for:

MC is extremely powerful, preferably one of the strongest characters in the series.
MC has loyal followers/servants/subordinates who genuinely respect and follow him.
The followers should also be very powerful, not just normal soldiers.
I like the feeling of the MC having his own organization, kingdom, faction, or group.
MC should be confident and capable, not constantly saved by others.
MC should NOT be a simp or constantly desperate for romantic attention.
Preferably little/no annoying romance.
I enjoy seeing the MC and his followers gradually build their power and influence.

I'm also fine with isekai, fantasy, reincarnation, kingdom-building, demon lord, or dark fantasy settings.

Anime I've already watched:
The Eminence in Shadow
Overlord
That Time I Got Reincarnated as a Slime
The Misfit of Demon King Academy
The Daily Life of the Immortal King
Solo Leveling
The Rising of the Shield Hero
Tsukimichi -Moonlit Fantasy-
Arifureta: From Commonplace to World's Strongest
The World's Finest Assassin Gets Reincarnated in Another World
Cautious Hero
Black Summoner

Please don't recommend the anime listed above.

Please recommend anything that fits this specific dynamic, including lesser-known anime/manga/manhwa.
Thanks!
