”Warming Dead SAGA” (ウォーミング・デッド SAGA Wōmingu Deddo SAGA) is the fourth episode of the first season of The Zombieland Saga anime and is the fourth episode overall.

Synopsis (Kotaro’s Diary)
''They ended up naming their group "Franchouchou" without my permission. The role of the group leader is now on Saki's shoulders. It seemed like a good idea that I deliberately made myself known as a producer. Speaking of which, it's not a bad idea that they ended up operating more independently. Now these talkative zombie idols who are a little motivated to make money can start earning a living. We will go to the hot springs to reach a commercial agreement. Hopefully, the secret that these girls are just makeup zombies won't be unraveled, or it will all end.''

Plot
Kōtaro gathers all the girls for another meeting, explaining that their goal and the group's funding is falling, he said that they no longer have funds left. Given this Kotaro announces that he has managed to schedule a meeting with a pharmaceutical company called "Hisonaka" at the Hotel Kasuien, with which he plans to form a society to obtain funds for the group. For this the whole group to the city of Ureshino, a city famous for its hot springs, where Kotaro would have a meeting with the president of the company. Given this, the girls are excited at the possibility of staying at a resort and being able to go to a public bathroom, but Kotaro prohibits them from using the hot springs, since this implies that they are without their human costumes.

Kōtarō takes the girls to their reserved hotel during the day. He noted that he has rented space for them and hopes that they will start practicing. He "runs away" without going into details. With the girls alone, Saki suggests that everyone take advantage of meeting Ureshino, Sakura insists that they follow Kōtarō's instructions. Yūgiri suggests to everyone that they should take time to relax and expresses interest in exploring the modern city. With everyone in a unanimous decision, the girls decide to go explore the city.

The girls visit a nearby foot bath where they take time to soak their feet. They express their current situation where they are still alive, even when they are dead, but then wonder how Kōtarō brought them back to life. Saki dismisses it saying that they should enjoy their second life. Sakura then asked Ai if they could all survive as zombie idols. Ai remains silent, but Sakura decided that she is completely willing to see the ideal come true. The rest of the girls agree with her and hope for the best in her career.

Upon returning to their inn, the girls decide to learn more about their sponsored product called "Saganship Z" before their presentation. They find it to be a patch of medicine for back and shoulder pain. When they try it on, they immediately feel that all their fatigue is alleviated, it is where the girls decide to promote the product during the show. With the show arriving, the girls began to patch the people in the audience to show their effectiveness.

After the show, Kōtarō goes to relax in a hot spring and the girls go to sleep. Saki decides to sneak into the bathhouses and confidently invites Sakura, who is concerned that they may be caught. Junko  overhears their conversation and wishes to join them, Sakura headquarters and the three of them sneak to the hot springs. After soaking, the girls are relieved to refresh their skins in the hot water in the bathroom.

As they reflect on their performance on the show, the pharmaceutical executive enters the bathroom, so the three girls cover themselves. Saki suggests that they hide underwater, the three of them go below the waterline, but Sakura accidentally hits her head and ends up being seen by the executive who immediately panics, surprisingly Saki and Junko leave trying to save Sakura, scaring even more the executive who runs away from the place, before the screams the rest of the group wakes up and go out to see what happened, they bump into the executive in the corridors of the resort, panic reaches the point that Saki slips and collides with the executive.

The next morning, Kōtarō approaches the executive to thank her for her affairs, only to see her in a fetal position and in shock, then they tell her that she was scared to the point of having forgotten everything that had happened the day before. Once everyone returns to the mansion, the girls saw a newspaper that read vague reports about the night the executive suffered at the resort, apparently being a kind of "joke", at which point Kotaro arrives to scold them.

The entire group gathered and discussed the situation, which Sakura apologized for her carelessness and vows to be more careful, while the rest said that there was no way that would affect the group.

Yūgiri considers the positive side of her entire experience that she is glad to have gotten along with everyone during the trip, and hopes that the girls will strengthen their ties for the future.

Trivia

 * It is revealed that a month has passed since the events of the previous episode.
 * Kotaro teasingly calling the group “Frankenchoochoo” (in the English dub) further supports the idea that the “Fran-“ part of their group name comes from Frankenstein.
 * One of the words Kotaro mispronounces “Franchouchou” as in the original, Fluorochlorochouchou, is a reference to the volatile hydrocarbon, Chlorofluorocarbon.
 * The title keeps a double reference, the first is the setting where the chapter takes place, the hot springs. The second reference is to the comic and TV series The Walking Dead since the last part of the chapter can be classified as zombie horror, there is also a similarity in the pronunciation of walking (U ~ ōkingu) and warming (U ~ ōmingu).

Dub Differences

 * Kotaro teases Sakura by saying “Franchouchou” wrong as Fran-choochoo and Fluorochlorochouchou in the original and once she corrects him he remarks sarcastically saying how “Oh so cute” it is. Whereas in the English dub, Kotaro mispronounces it as Frannyfannychoochoo and then as Frankenchoochoo, and when Sakura corrects him he instead comments on how they think they are fancy with their French-sounding name in a French accent.
