Hot Springs of Love.Tohka and Yoshino decides to visit hot spring. So Shido makes the arrangement for them to go to Tenguu Gokuraku Hot Springs. Perverted Kyōhei Kannazuki persuades Kotori to go too but has been exposed that he has ulterior motives. His punishment is to dig a hole and refill it for the next week. Meanwhile, Ryōko Kusakabe of the AST is informed that the DEM Corporation is going to send reinforcements. A hot headed Ryōko also finds out from her member that due to the increase in the Spirit's alert level the group's vacation trip is cancelled. Instead, the AST member will take Ryōko to the hot spring that Shido's going to. Origami, uninterested at first, receives a phone call from Shido where she overhears that he'll be going to the hot spring with Tohka, reluctantly decides to go as well. While riding in the car, Yoshino is given affectionate attention by Shido which frustrates Tohka causing Rena's car and road to be wrecked forcing them to walk instead. This in turn disrupts the train the AST is riding underground. The AST arrive up the surface unknowingly going in the same direction as Shido's group on the way to the hot spring. Kotori orders the group to do everything to stop AST in their tracks, pushing a stressed out Ryoko to breaking point, ordering everyone to use full force, turning into an all out war, using ridiculous and absurd objects in Date Town, from sticky substance to sleeping gas. A stray ordnance causes Yoshinon to fly off after the explosion. Shido goes to find Yoshinon in the midst of the firefight and is almost killed by Ratatoskr's Destruct Mode. Tohka saves Shido from the attack while overseen by Origami and fellow AST members. Ryoko and her team reaches the hot springs but due to Yoshino's crying earlier, it has frozen a few members leading to another disappointment. Kyōhei dug up a hot spring that Kotori and the group end up enjoying themselves in. Mana Takamiya is then shown arriving in Japan after the credits.
