My Very Own Guardian... Devil?

This is a little hard to process. So basically devils want to attack me. And this devil wants to protect me but I have to apparently sign a contract to allow him to invade my privacy! Not like this never happened before and this guy could just be joking with me! But then how did he get in here and his tail and wings move? This is insane!

Daniel Smith lived a pretty normal life and is going to high school soon like a normal 14 year old but then his life is thrown into chaos by some devils.

Tyson is a devil who unlike the other ones, is good and want to do the same work as angels, being guardians. However, there has never been a guardian devil before and they don't trust him that much.

These two characters' lives join together as Tyson becomes Daniel's very own guardian devil. Something tells me that this will be one very long ride!
