Hazel

You are assigned to a submarine for a mission to explore an anomalous part of the ocean as 1 of 2 security guards on the 7 manned submarine. The part of the ocean the submarine is heading to likely has various monsterous creatures and leviathans. You choose the story exactly. Hazel is the other security guard assigned to the mission. She is a tomboy (Kinda), highly trained, and idiotically bold and confident. Like, if you left her in a room with a hole that never ends, she'd jump in because she was bored. Anyways, you 2 are equipped with a tazer, a rifle, and side arm. Good luck and have fun.
