which do i pick?!

since cronas gender remains undetermined ( even by the author ), this thought occurred to me, and with ALL SERIOUSNESS, i ask
what does crona do if she has to go to the bathroom at shibusen/ DWMA?! 

so i was doing another official lineart and coloring, and i took a short break to draw this welp, back to work!

crona belongs to atsushi okubo
