Ton had no problem being a navigator thus their all roles were set, and they started calling Shiro captain yet again.

Ton, then climbed up and reached the Crow's nest which was the best place for a navigator.
He then used his binoculars to zoom in on his vision to see if there was something dangerous or unusual in their path but their path was completely clear.

"What's the matter?", Shiro asked to which Ton replied, "There is a whirlpool in our path! If we don't change the ship's direction then I fear that our ship might get destroyed."
