Pride x Familiar

In the wake of the Cataclysm which ended the lives of billions and brought the First Galactic Age to an end, human civilization fell into two camps.
Aventis – humans that are host to the Symbiote which makes them stronger, faster, quicker to heal, and harder to kill.
Regulars – humans that lack the Symbiote and are thereby physically inferior to the Aventis.
Ruled by the eight Aventis clans known as Prides, humanity has settled into an age of quiet, gentle prosperity that veils an undercurrent of tension and discontent between the two races.
For Caelum Desanto, a Regular high-school student living in the asteroid colony of Pharos, his reasons for resenting the Aventis grew the day his childhood friend was deemed eligible to bond with a Symbiote and thereby join a Pride, one of the eight Aventis clans that govern human civilization. But a near deadly encounter with a knife-wielding girl on the school’s rooftop eventually lands him in Galatea Academy, a prestigious institution attended almost entirely by Aventis students.
At Galatea, Caelum finds himself pulled into the machinations of the Student Council, who have entered into a shadow conflict fought out in microcosm between those that serve the Prides, and those seeking to topple them from power. Now Caelum is forced to make a choice: shelve his resentment for the Aventis and protect the Academy, or allow the people responsible for the deaths of hundreds, including his parents, to invade the school and place the faculty and students in peril.
