There is a continent called Carter, and there is a race there called Xiefut, which is divided into the terrestrial world and the floating world.
That is, the aquatic orcs group Talanduo and the terrestrial orcs group Caor.
Their relationship is not very harmonious.
Until one day, a human broke into their place of residence.
This is how the story begins.
In fact, it is an ordinary (possible) story about a human being who got lost in Carter's continent and was taken care of by a minor terrestrial orc, and then used his social knowledge to change the relationship between the floating world and the terrestrial world, and then lived together.
