I'm going to go out on a limb here and say, Any fan of Hetalia is gonna love this. It's epic. Especially the Spanish Armada V. England part.
Warning: Contains a bit of selfcest, incest, Japanese kanji and words, country personification, and view of undergarments, alcohol consumtion, and guns. And the firing of guns.
If any of that is offensive to you, go get a life instead of getting worked up over that stuff.
BTW, basically the Japanese parts are:
Vietnam bids France farewell, hoping that they'll meet again someday in the same place with a picnic basket. France replies that it sounds wonderful.
and then
- Spoiler:
Spain enters the ship to fight UK, and brings out his axe. UK apologizes and says that it's the end for Spain, and that it is a "real shame". He continues, saying that Spain will have to apologize for his mischief, and orders for him to kneel. Spain tries to get in a word, but UK repeats for him to "kneel" and shoots him through the leg.
