Risa and Mio find Yami reading fashion magazines. As Yami always wears the same battle dress, Risa and Mio bring her to a clothes shop and try to find her a new style. Yami finds some attractive new clothes but accidentally tears her new skirt protecting Rito from delinquents. In the end, she reverts to her normal clothes but ends up punching Rito when he sees she is wearing new frilly panties under her battle dress. When Haruna takes her dog, Maron, out for a walk she feels that someone is stalking her. She finds Oshizu on her break from Mikado-sensei's clinic and asks for help. Lala helps Haruna by making a machine that switches their bodies. Using the bait trick, Lala and Oshizu defeat the stalker. The stalker turns out to be a female dog-like alien who is actually in love with Maron, though Oshizu beats her up anyway as she is terrified of dogs. Gid orders Zastin to retrieve Nana and Momo, because they escaped avoiding studying the Royal Lineage of Deviluke. Nana and Momo hide in Rito's bathroom and the former beat him up when he sees them naked. Zastin appears and chases them to a bridge where Nana and Momo use their Pe-dials to summon dangerous animals and plants to attack Zastin and his assistants and Rito as well. Zastin is forced to admit defeat and Nana and Momo remodel Rito's house so they can live with Lala on earth. (Source: Wikipedia)
