Secret Guardian

This is Gabby, or Gabriel Decker, a 17 year old boy that lives in a very unfair world. The wealthy in this world are gifted with guardians, creatures that serve them like they're gods. Guardians were first introduced after many people became poor and the criminal rate rised to a dangerous limit, causing many rich people to become unhappy, forcing the government to ensure their safety. Yet, despite all those measures, school is still free for everyone, causing even more problems than wanted. Many poor children started stealing from the rich, bullying them and putting on fake innocence to backstab them. The result: Many rich kids started bringing their guardians to school, until they became bored and are now abusing their guardians to taunt the poor. Gabby is also one of the poor. He and his family live outside the city on a small farm, but his parents want him and his sister to become something better in life, so they force them to school. Usually he tries to stay out of trouble in school, but every now and then he still finds himself in the crossfire, getting hurt by someone's guardian or rejected by a group of other poor kids. One day he found a mysterious black small object in the woods. Not knowing what to do with it, he decided to keep it as a pendant, despite his parents asking him to sell it. There's been rumors of a forbidden kind of guardians. Guardians that used to be something else until they were forced to transform. The transformation however went wrong and turned them into forgotten creatures without a purpose. If a person finds their tear and decides to keep it, they're bound to them, following the person around like a shadow once found,until one of them dies. This tear is said to be a small object that's as black as the void, yet their glow reflects entire galaxies. And guess what? You're gonna be a forbidden guardian! And the object that Gabby found used to be your tear! (Can be literally anything, like a scale, claw, tooth, broken horn, actual tear)
