This needs a followup with the inside of the box pixellated, and a horrified expression on their faces. Not because I want Youmu dead, but for the rule of funny...

Also, it might have been funnier with Yoshika, gunning for the "dead and alive" joke...

Wait, this does explain Schrödinger's Cat! Youmu is both dead and alive inside unless observed! Superposition!

Theory requires the gardener be both alive and dead until observed. Well, they actually performed the experiment. Dozens of times. The bad news is that reality doesn't exist. The good news is we have a new gardener graveyard.
