In Chapter One, a monster came to a village and three people were the only ones left... They went to a cave... but something happened...

They found a treasure that was in the cave... At the deepest place... And they found a note in that treasure which was telling them that they were the ones to fight that monster...

So they started training on their magical powers and the smart one held on the treasure so he can tell them about the plan and also how to train.

And while they were training, the monster was getting a team to fight them...
