Velenka has some unfinished business after the wars. Spoilers for The Last Emprex.

Hokuu manages to escape the sparkle blue and is out for blood, Gray's blood

The Big Blue is not to be trusted. This especially goes for Gray. But what if your worst fear can be your greatest ally? Find out on Shark Wars! T for blood, no Gore! It makes me faint. I need to stop breaking the fourth wall and let you guys read. Darn it! Did it again.

Basically what the title says ( none of the characters belong to me except Zephyr and Shredder )

With Hokuu and Grimkhan defeated, and Barkley as First Assembly Leader, Gray enjoys his life in Coral Shiver as leader, but things are far from over. The jellyfish are threatening to go to war, and the orcas are in dispute with the shiver sharks. Will Gray have to give up his comfortable life in the reefs, become Seazarein again, and save the Big Blue before it is too late?
