A particular kingdom decided to summon a class of high school kids to save the world. The name of the world and the kingdom, you ask? That is not important. What is important is that the hero of this story, Andy, didn't receive a leveling up system and an additional awesome power by the goddess of that world. Even though Andy was the only one who knew that kind of fantasy story and really was excited for that adventure…

The king of the kingdom, who obviously was a wise old man, decided to politely ask Andy to stay away from the battles since he didn't sense much power in him. However, Andy received a power… the power to tame monsters and make them level up in his place.

"Ha! As if I would lose a golden opportunity like this! I will become the poke-… I mean a tamer master of this world!"

Upon discovering his power, Andy decided to have his own adventure in that world on his own. Will he defeat the demon lord that wants world domination for no good reason? We will eventually find out.
