A large ship with no idea where it is going, a few guests with their own concerns, what kind of story will their chance encounters create in four or five days?
If there was no time travel, no fairies and ghosts, no supernatural powers, and no everything arranged in advance, what kind of legend would happen to the protagonists?
There are food, music, dance, carefully verified history, adaptable strategies, different styles of martial arts, and rich and colorful emotions.
Martial arts can also live in the human world!
