This is an accepted solution.
The blog is really informative and nice. I as an anime lover myself totally enjoyed the information there and I think it is a great way to get your audience on your Shopify site. Just make sure you make research on what exactly to sell.
Once you create a site, post it here and the community members will gladly give some feedback to you.
My answer is yes, Shopify will definitely work great for offering anime related things to your audience.
Hyde here from Shopify. That's a great website! Very well-presented, and lots of lovely information on anime.
Shopify is an e-Commerce platform, so it's primarily aimed at people who want to set up their own, branded online store for selling products - and to sell on other channels as well.
Do you have products you'd like to sell? If not, you could possibly look into dropshipping. This allows you to source products from other suppliers and sell them on your store. There's more information on that here.
If you have any other questions, don't hesitate to let me know.
All the best, Hyde.
