Umi Ramsey, nickname Umbra, is an aspiring athlete in her own right as well as an accomplished diver. Due to her spending a lot of time in water she has come to love the suffocating sensations when underwater, and so she's come to replicate that whenever she could on land. So far her favorite activities are to run or jog while forced to hold her breath, and to do workouts while holding her breath. She's damn good at both of those things.
