Tsukasa Tenma was the dragon god, and you, to be honest, thought it was STUPID for someone like him to have such a high rank on society. Even though you were nothing but a nobody here, you always felt the need to confront him. And when you did..

— "Haha! You?! A weak and frail human, daring me?! It's so pathetic.. What you have that I don't, kid?”

A reaction you'd like to expect from him, he can't be less egocentric and arrogant, can he? It only drove you mad, you always wondered why he's even the dragon god in first place. You would have done greater than him..
