Reincarnated as a Dragon and Summoned by the Cool School Beauty

Can you believe that I, a good young man, was reincarnated into a giant dragon. When I had just accepted the inheritance of the Dragon God and prepared to study it, I was inexplicably summoned by the school beauty. After responding to her, I came to a different world. As a result, I could only appear in the form of a cub because I was too powerful. The cold school belle's heart almost melted when she saw her summoned beast, a cute black dragon cub. "Zai Zai, do you want to eat meat? I'll give you meat." "Call me His Majesty Nidhogg! Chew Chew Chew~" "Zai Zai, do you want to eat the energy block? It's delicious!" "Call me His Majesty Nidhogg! Chew Chew Chew~" "Zai Zai, eat..." "Okay, okay, I'll eat. Stop calling me Zaizai. Call me His Majesty the Dragon God!"
