Okay so this is a Hetalia/SAO thing, it's called Hetalia World Online. Basically, all the countries are NPCs and this is a multiplayer game, so lots of others join. Each country is a level. There will be 11 chapters, so 10 countries! The 1st is just you joining HWO... The way to beat the level is by making the country happy or killing the NPC that rules ir, and defeating the boss thats related to the country. Like, America would be a Hamburger boss... Or Iceland would be a Puffin ... yep.
