Someone else sees K.O. in confusion and appears, Mega Celestial Maia appears and introduces herself to K.O. and both of them teamed up to help find their friends. While the two walked in an alley, K.O. falls in a hole and Maia goes down to help him get out, all of a sudden they look at a giant footprint as K.O. mentioned from when the enemy stomped the ground making him lose his balance. Maia gets full intel and the photo of the footprint, they safely got out of the hole from the alley. As K.O. and Maia were walking into the street, the police car almost ran over them as Maia grabs K.O. and evaded the car causing them to scream in cover but it stops.
