<WARNING: ENDING SPOILERS AHEAD. DO NOT READ UNTIL YOU HAVE COLLECTED ALL THE EFFECTS. THE VIDEOS SHOW THE ENDINGS.>.
Ending #1
This ending can be seen by pinching your cheeks while you're awake. The screen will then fade to black,

Pressing Z or X causes Urotsuki to get up. She walks over to the shelf on the left, puts the books away, then proceeds to leave the room.
Ending #2
This ending can be seen by going into the Trophy Room in Urotsuki's Dream House and dropping all of your effects, then waking up. Once you do, save and check outside on your balcony. There should now be a staircase there, and if you walk up to it, she'll climb up the staircase. But, don't actually jump off. Go back down, and she'll throw it off the balcony, rid of it forever.

The next shot shows us Urotsuki as she finally opens the door, and proceeds to go outside. Then a new credit sequence rolls unlike the others: Urotsuki is on her Bike effect, passing by some other characters she's met through her adventure. It ends with her getting off her bike, and walking into a house. This is likely the good ending to the game, or the true one.
Ending #3
This ending can be seen by going into the Trophy Room in Urotsuki's Dream House and dropping all your effects. Then, wake up. Once you wake up, you'll find the same thing Madotsuki did: A staircase, leading off of her balcony. If you walk up next to it, she'll climb to the top. Press X, and Urotsuki jumps.thumb|300px|right|Ending #3: UFO Game
While she's falling, other characters you've met throughout the game will appear around you, with strings attached to some of their heads. Then it fades to black with a big THUD....And it turns out she had been in a claw grab game the entire time, and Urotsuki herself was a small plushie! A small schoolgirl wins Urotsuki, and then runs off with her. The next shot is of the girl sleeping, with Urotsuki, as a plushie, sitting on the floor next to her. Then the scene fades.
