Frightned, the people asked protection from the Emperor. In order to end this state of affairs the Emperor send one of his trusted generals, Minamoto-no-Raiko, who chose a small group of warriors, one of which was Kintaro (who had taken the name of Sakata Kintoki). 

They started their journey disguised as priests. Firt they found a woman who taught them the road to the fortress. They then met an old man, who was in fact a disguised god. He told them that once inside the fortress they will be invited to a banquet where wine would be offered to them, wine they should not, in any circumstance, drink.

Once at the fortress they were received by some bandits who took them to a great banquet hall where a handsome young man received them graciously and ordered his servants to prepare a banquet in their honor. Impressed by him, the men started to doubt if he would be the one they sought. However, they follow the advice given to them, I whilst pretending to drink they poured away all the wine.

The banquet lasted several hours, but finally their host fell asleep. Already prepared, Minamoto-no-Raiko and his men approached him and tried to subdue him. He then transformed himself into a giant demon. A terrible fight followed, but the determination and courage of the group of warriors won, and they defetated the demon, whom they killed. They then captured the bandits, released the women and girls abducted, and recover the stolen treasures.
