This is predominately aimed at the folks that don’t have or follow Ookuma on twitter, but he has an amazon wishlist. I know a bunch of folks have done their part to support the series with buying the BD’s, manga, LN, and other merchandise. However consider purchasing something off his amazon wishlist. Especially if you want to extend your thanks beyond likes, retweets, and comments. It would be nice to see the fandom give back to one of the dudes that has given us so much over the years.
*EDIT* I bought the Copic markers for him.
