Princess's Soul Beast

This is a completely imaginary world, and the summoning of soul beasts is only a small part of this world. But it happened that the princess summoned the strongest "soul beast" in the world. I racked my brains and combined magic, technology, immortality, and martial arts to create this messy world. I didn't know much about anything, but I knew a little bit about everything, so I created such a messy world. This is a fantasy world. This novel and its characters are purely fictitious.
