Another Idea
Gotta catch them all
Ten years old Myuu start her travel to be the best Monster Tamer there is? But, isn't she too overpowered for this?
It was Myuu ten birthday, a day she has been expecting since Monster Taming became popular.
A few years after Ehit death the monster rate of spawning and growth started increasing. It was slow at the start, but gradually become a very obvious threat for those living in Tortus.
Myuu's dad, Hajime Nagumo, after the insistence of some of his wives had a idea inspired by a certain creature collection game.
What did he do?
Using Creation Magic, and with her wives help he created an spherical artifact that uses Space, Metamorphosis, and Soul Magics all in one. Then he mass-produced it.
He called it Pocket Ball.
After beat a monster and weaken it enough you can trap him inside the ball, in a pocket dimension, where is brainwashed to follow you by a soul bound. Then you can use it to catch more monsters and so.
To be not misused it only work on monsters, and demons, and machines, and apostles and...
To be not misused it doesn't work on humans, demihumans or people on general.
Thanks to this, people started a new hobby that turned into a world sport, then a livelihood and now childrens when reach ten are given a starter monster and can travel and have adventures.
You may be wondering if this is safe, right?
Of course it is.
Thanks to the new implement on the Status Plates they are satelite tracked and can be teleported to the closer town if needed. The AI in the sat tells what is dangerous.
That's how on this day Myuu left her mother Remia with a hug and went on her journey to be the strongest Monster Tamer.
