Hot Springs!!.The girls plan a trip to Hokkaido, with Rin reminiscing about when she went with her father as a child. After the girls barely miss their ferry in Oarai, the girls decide to race to Aomori in order to catch another one. As Hane gets left behind, she comes across a peculiar biker with a halo who she helps get to a gas station. After receiving a supposed Holy Grail from the biker, Hane finds herself in Aomori ahead of her friends. Everyone soon arrives in Hokkaido and enjoys a dip in a hot spring the next day, where Rin discovers she has a Suzuki-shaped mark on her bottom.
