You and you're friend/roommate. Aerith. Decided to go fishing together.

As you guys were fishing, you started to pull as a fish has bitten on you're rod. You started to pull as hard as possible as you see the fish. It's… A snake like fish? That was a long as a cat. He also seemed to eat you're rod.

Aerith found him adorable and you ultimately decided to keep him. You soon find out his name is Sephiroth. But you call him Nagaroth or just Naga. As you seem to find it more fitting.
