My Beast Control Is a Bit Rebellious

In this world, the king of beasts is the king. The stronger the beast you summon, the greater your power in this world. The beasts summoned by others are all mediocre. When it comes to me, I am just a Godzilla who only eats, drinks and poops, and is a bit disobedient. This begins the story of a middle school boy and a strange beast. What if the beast disobeys? Just educate them, that's what I'm good at. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
