Chikyuu

Chikyuu literally means 'Earth' in japanese. It is in fact, an alternate modern-day Earth - officially called Chikyuu when japanese became the official global language (as opposed to English). It is the homeworld of the Reality Breakers, ISAF, CONFRONTERS, and the EmeRAID. They are various superhero teams who combat the Neo-Nubians, Razubots, and eventually the Anomaroids - monsters who threaten Chikyuu on a daily basis.

Chikyuu is the setting for the Tokusatsu inspired story : Choudai Henshin! Sekai no HERO Iwaku and is ruled by the United Nations.
