Following Mark's Unique Evolution, back on the Fifth Floor, he's devoured plenty of Monsters larger than himself.
Which is why, without realizing it, his body had gradually grown a bit taller and larger.
Tch-
Another fist barely dodged.
Still, compared to Zephyr who stood at about three meters tall, Mark's size was nothing impressive.
Punch-
Punch-
Punch-
Mark focused on his vision to dodge the successive incoming attacks.
Zephyr's reach was greater than his, which made counterattacking complicated.
Plus, whether it was because of the former's imposing stature and build or not, Mark continuously stepped backwards as he dodged.
Slowly but surely, his back approached the wall.
But that wasn't the least of Mark's problems.
Before that back could even reach the wall, he braced for the incoming impact.
Guh-
A powerful punch to the stomach.
