When Motoko runs out of clothes as they're all in the laundry, she is forced to wear a dress. Furthermore, her swordsmanship has been foiled by not only Tama-chan but also Keitaro. This leads her to doubt herself and things get worse when Mecha Tama-chan begins to create havoc.

Naru becomes possessed by an evil spirit and Motoko is the only one who can destroy it. Unfortunately, she doesn't know the technique to kill the spirit without killing the body and it's quite a predicament.
