Dagmyer once tried manipulating Kenshi into assassinating Lashara in the first episode, and is also responsible for recruiting some of the Academy's male students like Cliff, Alan, and Neil for the invasion of the Holy Land and later bandits lead by Cordyline and her daughter Lan. His Seikijin is blue and gold with a sword that can fire energy blasts from the tip and hilt and a shield as its weapons.
He became traumatized after witnessing the berserker state of Kenshi's Seikijin and seeing one of his own comrades Cliff fall to his death in the process and Kenshi almost killed him too, but was saved by his servant Emera in episode 11. Dagmyre eventually recovers in the episode following it. At the end, he finally acknowledges Kenshi's skill after he loses to him in a duel.
At the last scene of the series, Dagmyer is seen being in contact with Gaia's broken core, which slightly shines, harbingering a return.
- It was planned that, Dagmeyr would attempt to sire a child on Chiaia's mother, which made things a little awkward.
