Donat doesn't waste any time.
"Taste defeat!"
He lets out a guttural roar and charges forward, his war hammer swinging in a wide arc. He intends to overwhelm Rain with raw force and aggression from the start.
Rain, calm and cool-headed, sidesteps Donat's charge with minimal movement, dodging the war hammer's swing. Clutching his sword, he delivers a series of blows at him.
Donat, unable to parry the first blow, quickly recovers and uses his war hammer to defend against Rain's swift attack. He follows up with a powerful, earth-shaking blow with his war hammer, aiming to utterly crush Rain on the spot.
Rain, anticipating the hammer's impact, channels his faint golden aura into Unknown Sword and uses it to deflect the blow rather than meet it head-on. The force is enough to send sparks flying, and Rain uses the small window to land a series of rapid, precise strikes, targeting Donat's exposed limbs.
