Upon defeating the Last Boss, the ending will be played.
The first time it is played, you cannot skip it.
From the second time onward, it is possible to skip it with the confirmation button.

Also, after clearing the game, the door that was securely sealed inside 
the abandoned castle will open and you will become capable of challenging a new boss.
However, there is one condition. You must not be armed with one of the 4 secret weapons.

When fighting against this hidden boss, pressing the Y key will reduce its HP to 1.
While you can view the extra ending using this cheat, 
you will not gain the achievement for defeating the boss.
Also, please note that this boss does not have any violation scenes.
