So in the manga its a world where there are many species and his grandparents are like ogres while his dad is like part ogre and the mom is like part angel. One day he was walking home from school and he opened a trash bag to see a lizard and brough it home. Later the lizard kept growing and later they suspected that it was a dragon instead. So more on the guy is that he cannot do magic and his dad was a hero for killing a demon I think. He meets a girl who wanted to find the guy who owned a dragon because he went viral when the dragon practically broke the parking lot because it wanted soda and was having a temper tantrum. Then a guy was jealous and his family is famous for making magical staffs but ended up trending online for bullying. Later his father gets fired because of the bully so they became adventurers and while on a quest for herb gathering, he saves a princess who was kidnaps. I can keep going but I feel the post would be too long. So if anyone knows the title please let me know.
