ice armor negate

His eyes widened with surprise; the ice armor’s arm was already whipping around at
him. A brutal strike, bottom to top. The steel frame–like club easily slipped through the
thick floor without losing momentum, appearing to be drawn toward his torso.
It had enough weight and speed to crush a cargo container like an empty soda can.
“!...Ah-gahhhhh!!”
When he went to evade the strike, he felt a burst of air on his cheek. His bangs swung as
he instinctively realized he couldn’t dodge it. His right hand moved, mostly out of reflex.
His palm swung down in a reckless pounding motion at the incoming attack from below.
A high-pitched noise echoed through the ship.
Suddenly Kamijou’s palm broke out into a severe, cold sweat, which went up to his
elbow and then to his shoulder.
“...Urgh!” grunted Kamijou unintentionally.
The armor in front of him was motionless.

With the sound of a few snaps, the ice armor’s club split right down the middle. Then,
the shoulder holding the club broke apart, sending fissures vertically down from its
chest to its abdomen, cracking apart its thighs and knees, finally causing it all to topple
over sideways.
The pale light enveloping the armor’s body disappeared, as though the ice breaking had
changed the degree of light refraction.
