Motoko has a secret fear: turtles. So when Naru's pet Tama-chan falls in with the laundry, Motoko finds herself asking everyone for clothes, even Keitaro! The only problem is, without her own clothes, she cannot summon her ki, and therefore has no skill with the sword. And when Su's robotic Tama-chan comes crashing towards Hinata House, the residents definitely need a swordswoman.
