Ok, mc got bullied because a higher-class girl talked to him, maybe noble or just rich, so some assholes decided to go at him for it. he is at least as much as I read invulnerable, I think 1/2 or 1/4 oni or something like that. he then finds a lizard that apparently is a dragon and it becomes his pet. he is suspended from school, doesn't really care much, and just lives life. I think at some point he tries to become an adventurer but the receptionist is a piece of shit, I believe his dad was either a hero or something along those lines, he ends up running away with a princess on one job, as she is being attacked, I think his dad kills 3 of the people kind of in front of him. he goes to meat the king...

the setting is if fantasy settings actually happened but society advanced more or less to what it is in modern day.

I am unable to find this despite searching though several tags it would be in.

Kyuubo: Suterareteta Dragon Hirotta, Kaikata

thanks
