It's later revealed that Seliane's soul was split in two, light and dark, and later became Sylvia (light) and her older brother Sirius (dark) which makes the two of them Shadow Angels. The Shadow Angels harvest humans on earth in. The Vectors are the only weapons able to defeat the Cherubim Soldiers created by the Shadow Angels who have awakened after 12,000 years. Throughout the series, Sylvia-who is the reincarnation of Seliane- and Apollo's relationship evolves while they fight the Cherubim and Shadow Angels to prevent the end of the world. Sousei no Aquarion is about a group of people called Elements (element users) who are able to control the three vectors Vector Mars, Vectoru Luna and Vector Sol. During the first battle against the Cherubim, two of the Elements, Sylvia and Pierre encounter a 15 year old boy named Apollo who seems to be the reincarnation of Appolonius, or "Solar Wing" who betrayed his fellow Shadow Angels 12,000 years ago because he fell in love with the human warrior Seliane. She had come out in the hopes that her brother would be there, admiring the roses like he usually did at night. Silvia sighed as she walked through the garden. All characters belong to their respective owners. The Shadow Angels harvest humans on earth in order to obtain their prana (life force) which serves as engery for them and is also used to feed the legendary Tree of Life.
