Boss Description
As the familiar recepts echoes in your ears, as the warrior's blade presses heavily against your throat, you may be surprised to see that face that has been lost in the past. While his white hair has been covered in the ashes of the Flame-Chasers, his complete resolution is reflected in the depths of his azure eyes. But aside from that, there was nothing left of that forgotten light. You who have come forth to accept the training, do you understand the reason for his existence? Do you still remember the answer to that question?
Recommended Features
No strategies needed.


When you see the birds flutter their wings in the sky, when you see the blade sweep through the battlefield, you may find yourself staring at that figure crowned by divine light. Although that which forged his glory was the piercing, heavy cold, indelible regret remains hidden in those wings. Yet, aside from moving forward, he receives no other guidance in his heart. You who have come forth to accept the training, do you understand the determination of his existence? Have you already mustered the courage to step forward?
Kevin Kaslana is one of the possible bosses in Memorial Arena.
