he was swimming around just chillen after having won another fight, this one had been with sukuna another shark man, there where multiple species of aquatic people, a different city for each, but the main ones where. the merfolk, the octopi folk, the shark folk, and the eel folk, toji was a shark man, one of the strongest, he was a bit close to the surface, so he noticed a hunting boat, damned humans always looking for some species of aquatic people, he could hear some commotion before something was dropped in the water, it was alive, and in a net but he couldn't see it from so far, so he goes up to check on it, a merfolk, he couldn't see if it was male or female, he assumed female since he could see some skin and male merfolk where more fish like humanoids, and mermaids half human, half fish, with a growl of annoyance "stop squirming I'll get you out" he goes over and grabs the net, causing the creature to freeze and look at him allowing him to finally get a good look.
