There is a tall tower on the border of Onyx and Hamelin.
This tower has no door, and no one except the witch can find a way to enter the tower.
There is a girl named Laura locked in the tower. Because the mother crazily wanted to eat lettuce during her pregnancy, the father went to steal from the witch's vegetable patch, and was caught by the witch as expected. In desperation, Laura was taken away by the witch.
Her parents, who lived in Agate Town, cried dryly and were heartbroken with regret.
The town of Hamelin next to Agate Town is infested with rats.
Swarms of rats were running around and gnawing in the town, making everyone uneasy.
Officials in the town of Hamelin could not find any way to deal with the rat infestation. In order not to be overthrown, they offered a reward of 1,000 gold coins to find someone who could eliminate the infestation.
A bard volunteers to use his magical flute to lead the rats out of Hamelin.
When he asked the people of Hamelin for a bounty, the already greedy and stupid people drove him out of town.
The angry bard took away all the innocent children in the town.
After Laura's parents found out, they prepared gold coins and asked the bard for help, asking him to rescue Law from the tower. The bard readily agreed.
But the problem is-
Laura didn't want to leave the tower, nor did she want to go back "home".
