A Brexit Omiyage

I get that this is rather niche. To enjoy it, you must be interested in a) British politics, b) the Japanese language, and c) the Tokugawa Shogunate, as well as having the kind of sense of humour that would enjoy seeing all three in combination. I basically made it for myself, in other words - but just in case you'd like it too, here is the opening (and only) page of my projected manga, 「英国鎖国」, or, Britain in Chains.
