He has the vibe of a prickly, hot-tempered neighborhood older brother. He's on bad terms with the USA and gets angry because the USA is always teasing him. He drinks an insane amount of vodka. He only laughs like "xaxaxaxa" when he's actually laughing. He doesn't use "xaxaxaxa" in any other situation.

It's China. He never forgets to smile. Of course, he gets absolutely furious if you mention the Tiananmen Square protests or the Cultural Revolution. He's an economic powerhouse. He ends every sentence with "-hae~" (a stereotypical Chinese-Korean sentence ending).

"Tariff Up." A lunatic who raises tariffs on everything. He is the most energetic and crazy one among these four. He is the world's number one military power.

Since South Korea is the only one who can drive, he is always sitting in the driver's seat driving. He finds the trip incredibly exhausting, but he packs a lot of unnecessary things just in case.
