touma and stiyl ko

An ear-splitting roar came as the young man’s fist plunged right into Tatemiya Saiji’s
face.
(Ga, bah...!! Wh, ah, it went through...the shock-absorbing tech...?!)
Tatemiya’s body bent all the way backward. Before he could regain his lost balance, the
young man and priest both rammed into his body at full speed. Their pressure and
weight made Tatemiya Saiji feel like he’d been hit with a battering ram—he flew
horizontally through the air and slammed into the ground hard.
That’s when Tatemiya appeared to lose consciousness.
