Mori Arty is basically the cute kid in black who's obsessed with Milky Holmes. They're known for constantly giving advice or making requests to the detective group—always in the most ridiculously earnest way possible—which inevitably causes complete chaos. Nobody really knows what they're actually after, which is half the appeal. Fans often note that their interactions with the main cast are either genuinely helpful or absolutely disastrous, sometimes both at once.
