Isn't necessary but if you really want to understand the entire Kawakamiverse you have to read it before Horizon.

Without spoiling anything, OnC is placed on the real world, what you can say is our timeline but is also the break point where everything started. Horizon is placed thousands of years after OnC but despite that mayor time gap you can explain things on Horizon using the knowledge you get from OnC, you can understand the concepts in a better way too and knowing how the world on Horizon reached that point.

4. Edge
The cutting-edge era.
As people grew more and more used to the technologies gained during the Ahead era, they abandoned the earth for some reason and went into outer space.
The details are unknown, but a single star system caused a rebellion for some reason. In this era, the ether-like fuel source that was discovered during the latter part of Ahead became widely used and the technologies researched during the Ahead era were created to suit this world.

5. Genesis
The great foundation era.
In this era, people returned to Earth.
For some reason, people became unable to use most of the old technology and primarily used the technology gained during Ahead and Edge. This resulted in that super technology fully belonging to the Foundation World. They began to produce for themselves what can be seen as the foundations of what exists in this City World.
The earth was forced to revert back to the dark ages, but it recovered afterwards. However, the war that caused the end of the Edge era restarted and the world was destroyed.

6. Obstacle
The great obstacle era.
Some unknown means were used to create several worlds based on the destroyed Foundation World and they were repeatedly destroyed.
The aim was to create a world that would not be destroyed, but these strange worlds in which a few materials were removed or added to the Foundation World all ended up being destroyed.
Originally, this was thought to have been a single world, but investigations show an uncountable number of worlds were created one after another and each one had its history proceed to the level of the foundation era.
More about each of those will likely become known in the future.
