"As they say, if you can't beat them, join them. I'm not in for beating, am I?"

Acheron is a character in Fire Emblem: Three Houses. He is the head of the smallest noble house in the Leicester Alliance.

Profile
In Imperial Year 1185, Acheron is one of the commanders of an army sent to reinforce the Great Bridge of Myrddin.

If Edelgard was sided with, Acheron is sent by Claude to support Judith's defense of the bridge against the attacking Adrestian Empire. He is openly resentful of being forced to obey Claude's orders, as he views Claude as a "false leader".

If Dimitri was sided with, Ladislava sends for Acheron so that together they could encircle the forces of the Holy Kingdom of Faerghus. Acheron, though an Alliance noble, has sided with the Empire and seeks to curry Edelgard's favor by distinguishing himself in battle. If Acheron is defeated during the battle, in his final moments he expresses regret for allying with the Empire.
