Jonathan sat on Hellem's head and went into the Bazaar Sea. Half of Hellem's brain was composed of metal cells, which took the form of gears, steam canons, weapons and consoles. As such, its brain was like a fortress at wartime!
Isaac, the crazy alchemist, was a student of the legendary alchemist Marina. He had combined alchemy with Blood Witchcraft to upgrade a Child of the Sea to a level four creature.
With this creature, Isaac had been able to dominate part of the Stormy Sea. It was because of this that Jonathan noticed Isaac.
Jonathan was the third one to arrive at the Bazaar Sea, following Stormy Fairy Olicia and Mermaid Queen Gina. Besides them, there were also a large number of mermaids and Koutao sahagins holding steel forks and waiting outside of the film.
It wasn't long before a giant alchemy submarine arrived from a distance at great speed. It was being captained by Bobby, who then entered the film as well.
