Sakiri was using "Abdel's Pyrokinesis"!
And it was even at level 4 "Abdel's Pyrokinesis"!
Arthur, who also possessed level 4 "Abdel's Pyrokinesis," easily confirmed this with the Entry-level "Storm" perception of his General Puppet.
In fact, when the other party's First Mate, that 'Bluebeard,' ignited the flames, Arthur had already speculated.
However, the cautious Arthur did not take it lightly because he "knew the enemy and knew himself."
He liked to keep cards hidden.
What about Sakiri, known as the "Devil of Dokiman Island"?
Probability would suggest he would also have one or two cards hidden up his sleeve, right?
Otherwise...
He couldn't possibly have survived this far just on luck, could he?
As Arthur thought this, facing the incoming blaze, he simply raised his hand—
The Storm arose again!
This time, the wreck of four ships was completely obliterated.
Wood chips and twisted metal, like shields, protected one of Arthur's vests, 'Horton.'
