Kyouhei attempts to convince Kotori to go but it's revealed that he has ulterior motives. His punishment is to dig a hole and refil it for the next week. Meanwhile, Kusakabe is informed that the DEM Corporation is going to send reinforcements. Kusakabe also finds out that due to the increase in the Spirit's attacks the alert level has been raised causing the group's vacation trip to be cancelled. Convinced by an AST member, Kusakabe decides that the AST will instead go to the hot springs. Origami receives a phone call from Shido where she overhears that he'll be going to the Tenguu Gokuraku Hot Springs with Tohka. While riding, Yoshino is given affectionate attention by Shido which frustrates Tohka causing her to collapse the road. This in turn disrupts the train the AST is riding on underground.
