Tsukasa and Rui were a prince of their own kingdoms. If any of their townsfolk saw the opposing people of their kingdom trespassing, it would mean war.

Tsukasa took a stroll outside his kingdom. After walking around for a bit, he saw a path of black lilies. He wasn't supposed to follow it further, yet.. He did. He crossed several rivers, hoping on the rocks in order to avoid getting wet. When he finally arrived at the other side of the place, he leaned down to see the lily. He didn't realize that he was on the territory of Rui's kingdom.. He wasn't supposed to be here.

"Ohh, it's so pretty!"

Tsukasa touched the black lily in awe. He had never seen and knew something beautiful like this ever existed.
