Michi, a karate girl, is working hard to show her parents that she has what it takes to care for a pet dog. She and her friend Makoto, a karate boy, both dream of having their own dogs. But when Makoto's parents say his dream won't come true, Dishonesty creeps over Michi. Dishonesty is embodied by a yellow and green spider that changes sizes.


Michi is just trying to be a good friend. But after she gets a dog, Dishonesty weaves tangled webs around her. The spider monster even gets a hold of Makoto. With Dishonesty, Michi tells Makoto that it's no fun to have a dog and she acts mean to her new pet. It gets so bad that Makoto doesn't want to be around his friend anymore because of her actions.


Michi knows she is losing her friend, but she doesn't know what to do. Can these two kids apply the Dojo Kun values they have learned in karate in order to battle Dishonesty and save their friendship?
