oil teleport

Like water coming from a fire truck’s hose, it was not being emitted in an accurate
trajectory.
As if a giant hammer was falling down toward them, an amorphous red mass about
twenty meters across fell toward Mikoto and Shirai’s heads.
“!?”
Shirai was the one that reacted.
With her arms still wrapped around Mikoto’s waist, she travelled across the buoys one
after another. The giant hammer of flames struck the ocean, but it did not disappear
even as it evaporated a large amount of water. The sea of flames spread out as if it were
going to cover up the entire ocean’s surface.
“What is that!? Are they scattering fuel oil around or something!?”
