1x12 - Good Luck Girl!

Momiji's spry new personality, which has also extended to Kumagai, is a hit with everyone in school, but Ichiko remains suspicious that it is one of her plots. Momiji explains how, as a result of being washed in the human world, she has lost her powers and changed personality. Ichiko and the others attempt to turn Momiji back to her usual self with no avail. After some initial hesitation, Ichiko soon starts being friends with the new Momiji, finding it pleasantly peaceful. Some time later, Kumagai ends up getting dirty and reverting to normal, teaming up with Momo to try and revert Momiji to normal in the same manner.
