1x17 - Mew Mew Power

The data gathered by Masha reveals that the aliens originally inhabited the earth, but had to leave because of changes in the environment, ending up on an even worse planet. Ichigo is upset at this, but Ryou reminds her that it is not an excuse for trying to kill humans. Ichigo goes on a date with Masaya, which cheers her up, but the next day she is sick with a cold. The girls and Masaya visit, but after he leaves Kish appears. Ichigo escapes out a window, while the others prepare to battle multiple chimera animas released by Pie and Tart. Too weak to fight, Ichigo is unable to protect herself from Kish, but is suddenly rescued by a mysterious alien who introduces himself as The Blue Knight.
