Though it wasn't a well-known fact, it was a fact that even someone as carefree as Kokuryo had moments where they could be serious. As he leaned forward against the ship's rail, it was quite evident that this was one such moment for Kokuryo. Honestly, he hadn't expected to come across his sister while searching for that one dungeon. That dungeon a predecessor of his had conquered, the dungeon that held his future. He'd expected to come across a magi at some point, of course, considering he had no way of finding any dungeon on his own. His sister was an odd surprise, but not an unwelcome surprise. If anything, Kokuryo was happy to see she was still well. After all, all the responsibility had been dumped onto her after their parents passed away. Well, Kokushou was the oldest(and by far the least likely to just play around instead of fulfilling her duties). Still, just as he had said, Kokuryo wanted to help his sister in the only way somebody as free-spirited as he could help. By conquering a dungeon, by becoming a Dungeon Capturer, by gaining a Djinn. The more his kingdom had, the less likely it was that they would be attacked.
