Worst Ending: During the second battle with Dario Bossi, simply beat Dario.

Bad Ending: During the second battle with Dario Bossi, use the Paranoia soul to enter the mirror. After you beat the new boss, Aguni, go back to the other side of the mirror and get the magic seal. Go to the center of the castle and enter the boss door without Mina’s tailsman equipped.

Best Ending: Use the Paranoia soul to fight Aguni, pick up the magic seal, and go back to the center of the castle. When you enter the boss door have Mina’s tailsman equipped. You will now get a more extended version of the game and all you have to do is beat it.

Note: If you already obtained the items, then you will always get Potions.
