Chibi Zenki jumps through the wall, using his Bruce Lee-style flying kick. He goes all over the place at lightning speed and crashes foot first into Chiaki's TV, breaking it and frying himself by sheer accident. Chiaki and Saki are sitting at the table, wondering what's going on.
Regardless of this being an accident, Chiaki doesn't see it the same way and promptly punishes Zenki for breaking her TV. Afterwards, Zenki asks Chiaki if she's looking for trouble and fights her. As grandmother Saki witnesses the whole scene, she just walks away from the scene, leaving the children to their own wits.
