The danger below 1000 Meters (Patreon)

Umi (Requester's OC) took a PRAWN Suit diver to explore the deepests part possible to her of the ocean.

She tries to freedive inside, only being barely able to swim without a suit...let alone see in the darkness.

She fears for her safety for the mysteries of the depth, and the pressure getting worse and worse, so she quickly decides to return to her suit before things get worse.
