In an upcoming episode, she needs to play Liberty Maji back when she was little, and Momoka is having a hard time grasping the mindset of a child for her acting. The Sket-dan try to help by playing children's games with her, but it isn't until she and Himeko accidentally drink one of Chuu-san's drugs that they can really experience their childhood all over again.
