Episode Summary: Junpei finds a strange rock one day as he’s heading to his physics tutoring session. The teacher’s lesson about the Doppler effect is about as boring as it gets, until the rock that’s stashed in Junpei’s desk begins to take on a life of its own. It is, in fact, no ordinary rock, but a life form searching for some heroes who can help save the world from certain destruction. Junpei and his classmates, along with their professor, seem like they can take up the challenge.
The students are drawn into another dimension where they appear in the form of anime characters. The novelty of their situation wears off quickly when a giant, threatening Sphinx arrives and starts demanding the answers to riddles. It all seems like fun and games until they get a question wrong; the Sphinx then eats their teacher’s spirit. Luckily, their lesson on the Doppler effect turns out to be more useful than they anticipated, because it turns out to be the key to solving the next puzzle. With their teacher back in hand the group returns to the real world, but only until the Sphinx’s next deadly challenge.
