Synopsis

How vast is this Galaxy? No matter, it can't be that big, right? And then... After I'm done with Exploring it... What's next? I guess I should leave for another Galaxy then, right? Hah! Imagine... What if I make it my goal to Explore the Entire Universe?
Roan finds himself on an uninhabited planet with a group of Explorers. They received a cry for help and came to both rescue whoever it was that asked them to come, as well as explore what this planet held for them.
While doing so he and his little sister get separated from the large group, and while he's advancing to the Iron Stage, he loses consciousness and enters another Realm! Here, he meets Azmon... And finds out he has Azmon's Cube? What will the future hold for him? Come explore with Roan. Starting from this small planet to the Blue Rose Galaxy, to the Entire Universe!
