When you are on the deserted island in the beginnig of the game and are
asked what you want to do. (either escape or stay on the island),
repeatedly reply with an answer saying you wish to stay on the island.
After 3 times of answering, a THE END ... will show up on the screen,
wait about 20 seconds, and the game will continue, but instead of
colored avatars, there will be black and white manga avatars.
