Saint Seiya Star

An ordinary otaku time-traveled into his favorite cartoon, Saint Seiya, and became Seiya's older brother. He accidentally became a Sagittarius, and just when he was very proud of his talent, a stranger entered this world. They were human beings from a parallel world. They were familiar with the plot and tried to change their destiny like the stars. How would the stars with a system interact with them? This novel and its characters are purely fictitious.
