Full Name: Federative Republic of Brazil Gender: Male Likes: Football, Brazilian Funk, Samba, Carnival, Amazon, Rainforest Dislikes: Losing at football, Argentina, security issues, favelas Capital: Brasília Brazil is the overwhelmingly dominant country in South America in terms of territory, population, and economic scale, and it holds the justification of representing the voice of the South American region on the international stage. Based on its vast territory, abundant resources, and large population, it exerts influence as a major global economy (member of G20 and BRICS). Historically, it has supported diplomatic solutions and multilateralism over conflict and has actively participated in UN Peacekeeping Operations (PKO). Despite this potential, it has the lowest probability of becoming a permanent member among the G4. This is because its national power is insufficient compared to Germany, Japan, and India. It even lags behind Coffee Club members like Italy, South Korea, and Canada.

Full Name: Federal Republic of Germany Gender: Male Personality: Seriously logical, cold-headed, kind, calm, composed, workaholic Likes: Sausage, beer, labor and efficiency, order and rules, controlling the Eurozone (EU) Dislikes: Borrowing money and not paying it back, humor and jokes, mentions of past history, laziness and disorder, German Fourth Reich 💀 On the surface, it is one of the countries most likely to advance to permanent membership. Especially after rising from the ashes of defeat in World War II to achieve miraculous economic growth capable of leading the European Union while demonstrating political leadership, its capabilities as a candidate for the next permanent seat have been somewhat verified. However, as mentioned later, the reality is that it is difficult for Germany to become a permanent member due to issues regarding its past history, including war crimes during WWII, and the problem of Western European overrepresentation. Germany's greatest weakness in terms of justification is its history as an Axis power in WWII, and its history as a Central Power in WWI is also a negative factor. Since Germany's image isn't exactly bright, it is also difficult for Germany to become a permanent member among the G4 nations.

Full Name: Japan Gender: Female Personality: Perverted (Hentai nation), workaholic, kind, and has otaku tendencies Likes: Anime, hot springs and sushi, advanced technology and robots Dislikes: Natural disasters, rude behavior, attitudes toward the past Capital: Tokyo Like Germany, its national power is strong, but it committed many war crimes as an Axis power during World War II. Because it started the Second Sino-Japanese War and the Pacific War at the end of WWII, invading neighboring countries and violating the lives and dignity of many soldiers and civilians, it faces fierce resistance from China and South Korea—the primary victims of Japanese imperialism and colonialism—and some Southeast Asian countries also hold fundamentally negative views. Japan paid the second-highest amount of UN dues after the US from 1990 to 2017. As of 2004, Japan paid 19.5%, which was more than the four permanent members excluding the US combined. For reference, those four countries combined paid 18.5%. Later, in 2015, Japan's UN contribution ratio was 10.83%, followed by Germany at 7.1%, France at 5.5%, the UK at 5.1%, China at 5.1%, and Russia at 2.4%. Based on this history, Japan has ambitions for a permanent seat, but no matter how much it pays in dues, becoming a permanent member requires the unanimous consent of the other permanent members and a majority vote from the 10 non-permanent members. It always fails due to the absolute opposition of China and Russia, especially China, Japan's arch-enemy. For these reasons, it formed the G4 along with Germany, India, and Brazil, who are also considered candidates for the next permanent seats. It has been a non-permanent member 10 times up until 2010.
