There he met John Doe who explained that in order for him to enter the real world he needs Yumeji's body. Yumeji scared of this, tried to run away. However, John Doe found him and right before Yumeji was about to be made into a vessel, suddenly Merry appeared and battled John in order to get back to the Dreamworld.

John wanted to use him as a vessel.

John also helped Yumeji by giving him advice which led to Yumeji to create his Lucid Gadget. When Yumeji summoned him to help fight Noir and Landsborough, John helped him but tried to be aloof about it though his Little Chasers revealed his actual intent.

After helping them John got a cat as a vessel and takes the role of a pet in the Tachibana house and had Yumeji choose the name for the cat when the other members of the house tried to give him unwanted ones.

Quotes

 * (To Yumeji) "Deja vu is a sign of the intersection between dream and reality. Welcome, boy. Or should I say, thank you for accepting my invitation. My name is "Chaser" John Doe. As you visit our world, so I too have come to visit yours. But, I need a vessel from the other side to come out... You'll have to excuse me, but I'll be making use of your body. There's nothing to be afraid of. You'll be just asleep for a while. Now!"
 * (To Merry) "My apologies, little sheep. I'm headed the other way. I've come here to get outside."
