Yay for Matsuda! Well done He won! by ~wafflebaconkeeper on deviantART. This reminds me of that gif where it looks like Light is teaching Matsuda how to swim. Looks like Matsuda really took it to heart!
The top one is Crona's sex so it's what he biologically is. Gender is what YOU process as. Crona has never clarified for us so yes it is unknown. Either way Crona is still my favorite. Right above Kid.
