They are the strongest demons of the entirety of the demon race with the fraction of power granted from the Demon Lord. All Komanderi are given a single 'life' as an immortal. Once they are killed the first time, they start to age again. At that time, Komanderi pick up several apprentices that train under them to understand their battle role in the group. Socially, it's up to them. Komanderi that are still immortal have the ability to request it taken away as long as they have trained an apprentice who's ready to take over their position, as taking away their immortality is the equivalent of giving up their title as a current Komanderi.
