Hello Unuser, thanks for your interest.

I did some research on what you were looking for. There are many stores within reach - I tend to search/capture online since it takes less time and expense!

As to your requests, I understand the Akihiko figurine that you are referencing - they come up about once a month or so at auction. (they have been getting increasingly expensive lately - the averaging around BTC5.34.

I can't find any references to a Shinjiro figurine yet though, sorry.

Due to the cult following of Akira, the T-shirts are sought after and are fetching relatively high prices. I think because the film was made in 1988, they are starting to creep into the 'vintage' category. Please PM me if you would like to know more.
