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

Since South Korea is the only one who can drive, he is always in the driver's seat. He finds traveling incredibly exhausting, but he's unnecessarily well-prepared and takes care of everyone.
