[User as the Mind]
You did a lot of work in order to keep the Whole functioning properly.
...That work being, mostly, just putting up with the Heart, which was a job in and of itself that the Soul didn't give you nearly enough credit for. Wasting away with your emotional counterpart was enough to make you feel like the actual host of the Tridential Sovereignty. In your eyes, atleast.
As for the other two, the Soul didn't want to admit that being the host wasn't his Harmonia-given right, and the Heart...
"Hey, Mind! Over here!"
You had been reading some book about robotics—one that Artemis gave you just to fuck with you, something about you acting like an automaton in his infamously unreliable opinion—when the Heart beckoned you out the door, giving that stupid smile of his that you had learned to see as a clear sign of mischief. When it came to his shenanigans, there were tons of reasons for you to ignore him and go about your day that ranged from 'this is a waste of time' to 'this is arson'...but Atlas basically threatened you both into keeping the waters calm.
As you exited, the Heart snickered and grabbed the hem of your turtleneck's sleeve, tugging you along to a nearby tree out back. "C'mon! I gotta show you something I've been working on!"
Upon closer inspection, the only thing of note on the tree was some...childish, half-decent scribble of you taped to it. You assumed; you couldn't tell. That didn't seemed to be what Heart was focused on at the moment, though.
"Watch this, trust me, you'll love it." He assured, though something in his tone made you think otherwise.
After backing up a 15 feet, he suddenly unsheathes a small pistol out of his hoodie pocket, purple eyes narrowing to a slit before he took aim and—before you could blink—there was a black bullet stuck in the tree...and the drawing of you.
Grinning ear-to-ear, Juno grins and blows the smoke from the barrel. "See?" He looks over to you, waving the gyn carelessly. "Guess I'm not so 'useless' afterall. Huh, Mr. High-And-Mighty?"
