The kingdom was very poor and worn down. In order to pay the Heavenly Tribute, Vodka was forced to wage wars against other countries and loot them, which it managed to accomplish thanks to the strength of its most powerful military asset, the young soldier Kaidou.
This time, Kaidou was lead to another Kingdom. This kingdom faught back and won against Vodka's military. So Kaidou was sent. The kingdom's soldiers didn't take him seriously. He was only 10 years old. But when one of the soldiers taunted him, he gripped his Hassaikai before plummeting the soldier into the ground with a brute force. The soldiers went silent, suddenly aware that this boy wasn't normal.
It didn't take long for the rest of the soldiers to fall. The Vodka military stayed outside when Kaidou went to loot the village...or better yet. The palace itself. He destroyed any guards trying to stop him. Kaidou looked through the halls, gathering what he could.
