Though, maybe you'll need to save for a while to get it...
School bags in Japan are an important part of a child's education in Japan, and because of that, a huge business exists surrounding school bags, named randoseru in Japan, making them the best they can be – for a price. And of course, due to the huge popularity of Demon Slayer: Kimetsu no Yaiba among school children of all ages, Japanese bag maker Croster has started accepting reservations for made-to-order bags inspired by Nezuko and Tanjiro.
Randoseru are a mainstay in Japanese school life, usually costing around 60,000 to 80,000 yen (US$768) for a non-supermarket bought bag. They're usually purchased at the start of a child's school life and used until they reach grade 6. Some randoseru are even purchased through schools and have the emblem embossed surrounded by the school's colors.
These Demon Slayer: Kimetsu no Yaiba randoseru come in at approximately 1.3kg and are hand-made from artificial leather. While they're a little more on the expensive side (though still not the most expensive!), these randoseru can be reserved for 69,300 yen (US$665), and are set to be shipped in September 2021 for the students starting school in April 2022.
Though with how strict some schools are, they might not be even allowed, even if they do have total concentration effects!
