The Only Aura User In Magic World

I thought that the giant fish that tried to eat me before was the Kaiser Whale. But no. That was just the Kaiser Whale's meal.

The Kaiser Whale easily devoured the giant shark. Luckily, there's no Crab People or Sea Serpents near this area. So they didn't get swallowed.

As soon as the Kaiser Whale breached as he swallowed the Giant Shark, his eye level is the same as us who are so high in the sky by riding on Andro's head. And Andro greeted the Kaiser Whale at that time.

As Pawzer said before, the Kaiser Whale could reach this height easily. The waves he created by breaching out of the water are strong as well. They almost reached Angela to the point that some sea monsters who couldn't even walk on land almost reach her.
