Double Flame Sword Explosion

“Ash to ash...”

Kamijou looked up in shock. From beyond the giant flame god, a flame sword had
appeared in Stiyl’s right hand.
“...Dust to dust...”
And another one. A bluish-white burning flame sword extended silently from his left
hand.
“...Squeamish Bloody Rood!”
With those power-filled words, he swung the two flame swords horizontally so they
would slice straight through the giant flame god from left and right like a giant pair of
scissors. With his right hand sealed by Innocentius, Kamijou could not block anything
else.
(Shit... I need to run!!)
Before Kamijou Touma could even shout out, the two flame swords struck the giant
flame god and it all turned into one giant bomb that exploded.

When the smoke and flames cleared, the entire area looked like hell.
The metal railings had warped like sugar sculptures and even the floor tiles had melted
into something like glue. The paint on the walls had peeled so the concrete was visible.
The boy was nowhere to be seen.
However, Stiyl heard the footsteps of someone running along the passageway
downstairs.
