So a certain section of the Not!Japan army turned traitor and sided with the Not!Germans to have their army of zeppelins and tanks invade Not!Hokkaido and destroy the Not!Ninja enclave. History is weird yet familiar in this setting.
You know, I love how the manga raises the stakes time and again with threats that are ridiculously unfair, yet also understandable and believable (it's not as if humanity didn't use tanks, armored trains, chemical weapons, dreadnoughts and zeppelins back in the day). But while I hope Kai will defeat them with his magical boob-sucking, I also hope he will put more effort into helping Albion and friends improve their own technology. At this rate, they're going to be left behind.
