[So there are a few things to note right away. One: Mu doesn't have a shirt on. Two: He appears in the middle of a martial art
set, but doesn't seem to notice the change of scenery. Three: He's intensely focused on what he's doing. Four: He's adult again.
And he does this for no small amount of time, either. He continues sets for what would seem several hours, the movements coming like second nature to him. Finally, however, he slows, settling into a few sets of Tai Chi to cool down before he takes a seat and lifts his mane of hair off his neck. ]
