Doraemon: The Strongest Suneo

Axis powers-focused story. The author is a fan of Germany, and the Iron Cross era under the great Wutong is completely scrambled in this world. Logic no longer applies here. History and war have become unrecognizable, and Doraemon, ship girls, Conan, and many others all coexist in this age. See how our protagonist gets involved in all kinds of events as a mere "bystander"...

P.S. This is a harem novel.
