The lich of the Space Death Legion was moving swiftly, traversing space to keep its distance from the master, while attacking with its black magic.
At the same time, the countless monsters he had raised from his death were having an even fight with the blood warriors, the family and the remnants of the army.
Viktor and the blood warriors displayed the great skill [Blood Control] that used the blood spilled on the battlefield to slow down the monsters and destroy them.

Akiba used a skill he called [Dance of Death], utilizing various passive augmentations of his class and demonstrating masterful control of his mana.
He had a certain affinity to darkness and wind, so these two attributes were the ones he mainly used in combat, making him a classic and masterful assassin.
