After the devils catch a television advertisement for Chitose in Hokkaido, Yurine Hanazono suggests that everyone should take a trip there. All of them readily agree to the excursion, except for Jashin‑chan; she is forced to join when Yurine threatens her with a chainsaw.
As the group begins wrapping up their sightseeing for the day, Jashin‑chan accidentally allows a stray deer to eat the hotel check‑in ticket now they need. Coincidentally, the fallen angels are also traveling to Hokkaido and end up staying at the same hotel. When Jashin‑chan runs into them, she has no choice but to challenge the angels for their ticket by quickly racing around Lake Shikotsu together.
