The Berserk Demon that used its claws was much faster than when it wielded a weapon, and Lancelot was unable to dodge in time, only able to swing his sword toward the demon's claws.
At the moment of collision, Lancelot's wrist twisted slightly, rotating the longsword in his hand half a turn, so that what met the toad-like claws was the sword blade instead of the back.
There was a squelch as all four fingers of the Berserk Demon's right claw were severed. But Lancelot didn't pause, his longsword drawing a half-circle in the air, cleanly severing the wrist of the other claw that the demon swung at him.
However, the Berserk Demon had already entered a Berserk State; its limbs didn't stop for a second despite the horrendous injury and struck Lancelot solidly, sending the Human Knight flying.
Lancelot rolled to his feet from the ground. Although he looked quite disheveled, the claw-less Berserk Demon was clearly more wounded than he was.
