Kak! Kak!
Eren's sword was quickly corroding, making a strange sound every time it hit the dark red energy surrounding the sword.
But Eren didn't stop.
Rather, he increased his speed even more.
His muscles strained, and he felt a sharp pain from the excessive movement, but this was nothing compared to what he had experienced before.
The eyes of the vigilante watching this suddenly widened.
At first, they looked at him with worried eyes, but as time went on, it became difficult to follow his movements with their eyes, and he quickly cornered the madman.
It was then.
Phiss!
Blood suddenly spurted out from the arm of the madman holding the sword.
As Eren had intended, the madman's body could not keep up with the sword's will and was overloaded.
"Kwaaaaak!"
The madman screamed desperately.
The muscles and joints of his arms twisted, and the veins bulged as if they were about to burst.
