Touma One-Punch + Assisted Tackle

(Good! The spell is complete! Once the sword stabs through, be prepared to taste
my counter……!)
Tatemiya Saiji stuck his large tongue out, licking his lips greedily.
The priest charged on and slams into the boy’s back. The flame sword in his
hand would pierce through the boy’s body and towards Tatemiya’s abdomen.
(I win!)
—But, things didn’t turn out as expected.
Tatemiya had already prepared an anti-flame spell, intending to send the heat and
flames caused by the explosion of the flame sword back. But nothing like this
happened.
The boy forcefully pulled his right fist back, ready to slam him like a hammer,
and the priest’s flame sword just happened to land on his fist.
Bam! A sound similar to that of a balloon bursting was heard. The priest’s flame
sword exploded into fireworks, and vanished.
“Ah……? This is…… Wha—!?”
Tatemiya, who had already set up the anti-flame spell and thinking about a
counter, did not understand a single thing that was going on.
BAM! A terrifying sound was heard as the boy’s fist landed brutally on
Tatemiya’s face.
(Ka……aaaa……! The anti-impact spell……was broken through……?)
Tatemiya’s body flew backwards. Just when he was about to stand upright, the
boy and the priest slammed into him. Being hit by the weight of two people,
Tatemiya’s body rolled on the ground at an astonishing speed like he was being
hit by a large hammer.
Just like this, Tatemiya lost consciousness.
