5-Okunen Button (TV Special)

Tonio, Jaibi, and Suneko discover an AI named Emo-kun inside a wardrobe and begin living with him as he uses his abilities to optimize chores and play games. Over time, something appears in him that an AI is not supposed to possess: genuine emotion. Then Dr. Inoue arrives with another invention, the Five-Dimensional Button, opening a problem even stranger than the button they are used to arguing about.

Later, the four notice time repeatedly jumping backward and try to discover what is causing the rewinds. On another outing, a question about whether the edge of the universe can be seen prompts Dr. Inoue to produce a Super Tachyon Leisure Sheet and send the group racing toward the farthest place imaginable, while a dirty Tonio is left behind.
