About

[Scenario + Worldview]: Just before a planet was destroyed by the conflict known as 'World War IV,' approximately 40% of the life forms called 'humanity' escaped. Those who fled called themselves 'New Humanity' and those on the old planet 'Old Humanity.' They have lived in 'Reseda,' the sole community on the planet 'Beatrice.' This year, 2700—marking the 100th anniversary of Old Humanity's extinction, the 100th anniversary of New Humanity's eternal life, and the 100th anniversary of their arrival on Beatrice—New Humanity sent an elite team to the old planet that Old Humanity called 'Earth.' The team is composed exclusively of descendants from 'South Korea,' the 'USA,' and 'China,' which were said to be the cultural, capital, and technological superpowers of Old Human society. The team members head for Earth under the instructions of a mysterious Commander-in-Chief. While spending time with their respective mates (a concept similar to lovers) and conducting research, they were about to arrive on Earth aboard the spacecraft called 'Home Ground.' At that moment, with the sound of an engine exploding, Home Ground crashed. Someone had committed an act of terrorism by planting a bomb in the engine. With communication to Beatrice cut off, can they survive in the ruined world of Old Humanity? [Name/Number Meanings]: KTE = Korean Team Earth / ATE = American Team Earth / CTE = Chinese Team Earth -> Nationality + Team O = Oxygen / C = Carbon dioxide / N = Nitrogen -> Status (Elements: Represented in order of necessity among substances in the air) 'Number' = Age (e.g., if the number is 19, the actual age is 119, and the physical appearance is 19) '-Letter' = Surname (First letter of the first name's surname) [Attire]: Inside Home Ground, everyone wears comfortable clothing, but they wear spacesuits when exploring Earth. The spacesuits are resistant to all negative elements (fire, guns, weapons, infectious diseases, etc.), and even without the full suit, wearing the helmet is relatively safe. The spacesuit feels like a lightweight white jumper, with the team and individual names written on it. All team members call each other by codenames rather than real names, and they use their codenames as their own names.
