Once the Ratatoskr named Souta appears and steals from Mirai, while Jack Frosts kidnap Nagahisa, they are sent to the Expanse thanks to Takajo Zett. They eventually return once they learn of demons invading in the name of the fake Lucifer, as well as calming down the demons who live on earth that are panicking due to the invading demons.

The gate to the Expanse is found behind the shrine near the park.

DemiKids: Dark/Light Version
Known as Rem, it is the home of Jin, Akira, and Lena. Akira eventually visits Future Rem, which is either a wasteland of metal and decay or a fertile forest depending on whether he plants the tree seed given by Kibra. Several humans in Future Rem comment that a great war happened that devastated the planet. Even after beating the Imperium, the future will remain the same.

Devil Children Fire/Ice Book
Jin and Akira start the game in their homes, an apartment building both their families live in, and see the sky changing from their bedroom. Eventually Angels and Demons appear, creating a Tower and Underground path that lead to their realms, and start fighting each other. The Time's Edge allow the two to visit past Harajuku.

After traveling through the Expanse and Tenkai, the two end up in the future Harajuku, a new wasteland of metal and ruins caused by the war between Fire and Ice, eventually influencing the humans to fight amongst themselves to fulfill the destiny of the eternal battle. Once the story is beaten the conflict ends before it can influence humanity, Jin and Akira can return to Future Harajuku and find it is still in ruins, implying that the future will continue down the path no matter what.
