Slimy Sextet

The hero Quinn has slain the Demon King and brought peace to the world with the help of Celeste, the great fairy of the forest. Now Quinn must repay Celeste for her aid with the promised cost: her firstborn child.

However, Quinn refuses to settle with a husband, nor have a firstborn child that Celeste can claim. Using this loophole, she plans to get out of ever paying what she owes.
