"Kekekek!" Grating cackles mingled with the clash of bone spears.
Several young males competed in biting and thrusting in a pool, fighting so fiercely that scales flew.
A Fishman with algae-like spines on his back drove a bone spear into his companion's shoulder, splashing filthy green blood and drawing shrill cheers from those around them.

Countless streams of water were instantly blocked, their backflow thrown into chaos.
At the same time, a second wave of searing explosions erupted from several points along the side walls!
