Berman

Home town: Tearmoon Empire, Berman Viscounty

The head of the Viscount Berman family, which has a fief next to the Rudolvon family. He's concerned that his territory is smaller than that of the Outland Count Rudolvon, who seems to look down on him as a county aristocrat, and he plans to forcefully cultivate the Sealence Forest located between their territories.

In the previous timeline, this led to the outbreak of civil unrest among the Lulu tribe, which eventually led to the destruction of the empire.

In the timeline of the main story, Mia successfully dealt with the above problems and he became a loyal subject who devoted a great deal of loyalty to Mia.

(Spoiler from the Volume 3 of the LN) His loyalty was so great that he supported the imperial family even after Mia's death, even in an alternative timeline future (the future in which Miabel was born), which diverged from the timeline of the main story.
