slides down a giants back

Kamijou and Marian were tossed into the air.
Her fight had likely ended as soon as this final attack was launched, so she had passed out.
Kamijou grabbed at her with both hands in midair.
He ran from the broken sword and over the giant’s shoulder, dropped down to its shoulder
blade, and made his way down its curled-up back. He slid down like it was an insane water
slide from a foreign resort.
