After Ranpha buys a new fortune telling board, she runs into Maribu who is critical of her dismissal of science. To prove his point, he challenges her to a duel in which he puts his future predicting robot in competition with Ranpha's board to see which is more accurate. With the loser providing free meals and deserts for everyone, all involved try to make the predictions come true. However, both devices are correct in every question. The other people figure out that the world changes according to predictions from both devices. When Mint asks a question with only one answer and both devices make different answers, the world wipes out and reverts to when the Galaxy Angel Project was being proposed.
未来が分かるという羅盤を手に入れてごきげんのランファ。だが「非科学的」とマリブにバカにされる。言い争いになった2人は…。
