S1·E49 The Awakening of Blue – Another Appearance!

Ryou and Keiichiro tell the girls to take a vacation, feeling the final battle is approaching and wanting them to be refreshed. Ichigo, however, cannot find Masaya to enjoy the downtime with. Meanwhile, Kish tells Pie and Tart that he is going to use the Blue Knight's powers rather than waiting for Deep Blue to awaken. Pie disagrees, but Tart is convinced. They release all the chimera animas they have in order to distract the Mew Mews and the Blue Knight, while the aliens search for Masaya. Ryou realizes it is a trap and sends the Mew Mews to find Masaya as well. When the girls eventually find him, he is lying unconscious. Mew Ichigo approaches him, but he transforms into the Blue Knight. All of the strange energy in the city gathers around him and he transforms again, into Deep Blue.
