Rohan's Adventures in Search of Inspiration

The famous manga artist Rohan had recently run into a problem... After traveling all over the world to visit famous places, he finally faced a creative slump. Then one day, a System from another world suddenly appeared and asked to bind with him. It could take him to other worlds and even to eras in the past. So Rohan went to another world's Morioh to see the strange Rock Humans and Locacaca fruit. Hmm... It's really different from Angelo! He went to the so-called eighteenth century to watch the SBR horse race, running alongside various racers and witnessing their six-thousand-kilometer journey. Rohan stared in silence at the Saint's Corpse that had somehow fallen into his hands. (There's probably no need to worry about spoilers. I expect I'll alter the plot beyond recognition. Maybe even fans of the original won't recognize it.) Theme: The world is vast. Get out there and see it.
