Planetary Soul

17 year old Ethan Mosuma is not an ordinary human like all others on Earth. Rather, he is known as the vessel for the Earth's soul. Human's who hold the precious souls of planets are known as 'juko'. Juko are first informed of their specialty the second they are born. Ethan's main objective is to search for the other 8 juko and perform a ritual that would create an immortal being. This needs to happen because a planets lifespan is as long as its vessel's, unless when they die, he/she has enough strength left to pass their corresponding planets soul into an unborn baby. This has been going on since the planets and humans were first created, and this is why the souls of these giant rocks have weakened, and do not have the strength to go on. Ethan found this out during a dream he had when he was still little, and he did not want for his planet to be destroyed because of his own death. That is why he had decided to set out in search of the 8 juko. If the immortal being is created, the planet's souls will combine and have a never ending lifespan allowing for footing of future generations. Only one problem stands, beings from other galaxies claim that the milky way is in their way, and the easiest way to get rid of it is to execute the 9 juko.
