Mizuki's cool backpack of stickers comes with a completely random bonus water bottle tucked into one of the side pockets. It is plant themed :) If he opens the water bottle, there are forest-themed sticker sheets in it... neither the Shopkeeper nor Trader will know where this came from if asked. It is a gift.

For some reason when I clicked the outfits to look at Mizuki, it downloaded them to my computer, so I have Mizuki with me forever now. Also what the fuck I didn't realise Flamebringer was in that AS pic until today what the fuck

Anyway, there is nothing significant about the state of either outfit... save for his IS3 outfit, which has a handwritten note in the pocket:

"If your hair gets too unruly, make sure to come see me immediately, okay? See you soon, Mizuki!
