|This article is about a/an planet in Kamen Rider Gaim.|
This world was originally an empty, deserted planet located at the edge of the universe. Later, Kouta Kazuraba, as the Man of the Beginning, sends all of the Inves and Helheim plants there to live their peaceful life without harming humans on Earth.
As a gift to Kaito's spirit, Kouta and Mai replanted and revived the Helheim Holy Tree of Zawame City in its original location, appeasing Kaito's spirit. The tree also serves as a gateway for Kouta and Mai to traverse space between Earth and the New Planet.
After the planet's transformation in the series finale, it's likely that the environment there resembles Earth.
The planet was invaded by Megahex who assimilated Mai and fought Kouta.
Kouta briefly left the planet to fight alongside his old allied Kamen Riders Wizard and Drive as well Ghost and Ex-Aid to fight the Next Genome Institute. Once the battle was over, Kouta returned Helheim at Mai's side.
When Kaisei Mogami's Enigma device threatened to collide the Earth of Kouta's universe with the World of Build, the Beginning Man felt the disturbance even on his adopted home planet. As such, he set off to assist his fellow Kamen Riders in stopping the Enigma and saving both realities.
