This is a navy blue backpack from Master-Piece's Game capsule. I purchased it when I was in Osaka from the Master-Piece Flagship store. It was more or less a spur of the moment purchase, as I just really loved the look and also the functionality of the front pocket that swings out so you don't need to take off the backpack to access it.
I used on and off for about 6 months, but at the end of the day, I just have too many backpacks and this one doesn't get enough use.
I purchased it for 29,000 yen plus tax at the time, and it looks like it is going for over 330 euros or so on websites. This bag is used, but generally in good condition, though one of the zipper pulls shows slight signs of wear.
