A Hetalia fangame programmed into an English-language game by Kia Lao based on the original Japanese fangame.

Japan creates a new video game. However, an error happens, the error becoming sentient (taking the form of a doppelganger of Japan) and sucks characters into the game. The error is slowly trying to trap them in the game, and sometimes uses his powers to 'infect' people with a virus, causing them to come under his control.
