The Curse of SAGA

""With the beginning of the Reiwa era, Saga will face a cataclysmic threat. A cataclysm wherin no one will think of Saga anymore, and it will vanish from their memories.""

The Curse of the Saga Prefecture, also known as The Curse of Saga, is the primary antagonistic force which has plagued the Saga Prefecture since ancient times and continuing into the present day. The curse ensures that any person who may bring prosperity to Saga will be struck down before doing so, effectively dooming Saga to a path of ruin and destruction.

Origin
The curse of Saga (as it is known in the Zombie Land Saga universe) is inspired by the historical accounts of Xu Fu, an ancient Chinese alchemist who allegedly visited Saga in his search for the elixir of immortal life. The curse also seems directly linked to Jofuku, as he is shown to visibly suffer as a direct consequence of its power.

The curse takes different forms throughout time. For example, during the Meiji era, the curse manifested by misleading people into war and destruction. In the late eighties, when there was a period of relative normalcy, the curse was embodied by sagako, demons with physical forms who terrorized the residents of Saga. In modern day, the curse appears as natural disasters and/or freak accidents targeting Franchouchou's ascension.

Franchouchou itself was created by Kotaro Tatsumi as part of his Zombie Land Saga project, designed and ultimately purposed to defeat the curse and thereby save Saga. Because the curse promises to kill any individuals who may bring glory to Saga, the project is Kotaro's attempt at circumventing its power by producing an idol group composed entirely of undead zombies.

Skills

 * Ominous Presence - The curse manifests its power in response to a threat, the greater it is, the more effort it will make to stop it, which means that when Franchouchou's group were ready for their concert at the EFS and it itself would bring Saga recognition, Saga's curse would not hesitate to use all its available power to stop the girls or even destroy Saga days before they achieve their objective.
 * Accidents - The curse sees as a threat anyone who wants Saga to be more popular, so it will generate accidents or small or large inconveniences that will hinder Saga in his progress.
 * Misfortune - Franchouchou's girls were cursed by the curse with bad luck, but being dead and with Kotaro on top of them, this bad luck is not effective, in fact the curse tried to take them to the sea and try to expose the girls multiple times during the last episodes because the curse does not want the people of Saga to have something to remember.
 * Deaths - It is implicit in these season 2 episodes that memory is the factor that allows Saga to persist, not its official recognition as a prefecture, because committing an assassination against Saga's rebels effectively reduced the number of people who remember Saga in their hearts. The death of the girls is the last measure of the curse to end anyone who dares to interfere with Saga's popularity.
 * Natural Disasters - Shown in the latest Revenge episodes, Saga's curse is capable of causing natural disasters that are sure to have killed multiple people.
 * Supernatural Beings - TBA
 * Zombies - TBA
 * Demons - Spawn demons in Saga to destabilize the area and stop people from thinking about Saga Prefecture.
 * Aliens - Literally manifesting as an UFO after the Franchouchou benefit concert became popular in various countries.

Weaknesses

 * Onions - Onions are the method of sealing the Sagako demons, a physical manifestation of Saga's curse that tried to end the prefecture in 1989-1999.
 * Memory - Saga's collective memory is what allows Jofuku and possibly the girls to exist. This is Kotaro's plan and that is the way Kotaro plans to save Saga and why it has to be the way he is doing it, if all mankind remembers Saga, it is impossible to destroy it from people's hearts and since the curse only operates in Saga's area, it will be impossible for it to do anything.

Franchouchou

 * In Saki's death, she is the leader of a cycling gang that wants to take over the island of Kyushu and then her country. Due to her influence and the gang's growth, the curse tried to stop Saki and as a last resort left her to die in a motorcycle accident that she initially survived, but by leaving her alive for her gang to see what happened, with the traumatized gang they stop the project of taking over Kyushu
 * At Lily's death, she was a popular actress in Saga. She makes Saga popular and known to her goes against the intentions of her curse, which is why she killed her by growing her hair at an early age and triggering a cardiac arrest from stress.
 * In Ai's death, Iron Frill is a very popular group and Ai is its center, a living legend. Their concert at EFS will be one of the largest in the area. The curse killed her before the concert became a success. The curse killed her in a way that will leave a negative impact on the place so no one wanted to remember the place. Even newspaper articles highlight the bizarreness of the incident.
 * With Junko's death, she already became popular and well-known, a living legend similar to Ai. Her when she went to Kyushu near Saga to bring popularity to the place. The curse stopped her immediately upon crashing the plane and she had no restrictions on collateral damage, as Junko was in a plane crash with hundreds of other passengers.
 * In Tae's case, the curse is already stopping her to "save Saga" by spawning demons to stop her group, we still don't know anything about Tae but most likely she has been brutally killed by a very powerful demon.
 * Yugiri was the victim of the curse or, more accurately, of an exchange. Kiichi was a nameless boy who wanted to get Saga back, but who became a potential victim of the curse (and politics) in the process. Meanwhile, Yugiri had friends in high places and her death was almost covered up and wiped off the map. If her death had been made public in some way and it had been made public that by helping a child to recover Saga, it was accidentally started caused a riot/attempted revolution. Saga would have gotten a lot of attention from that kind of news, like news worthy of a history book. The curse would have had a harder time keeping Saga "forgettable", preferably non-existent."
 * This also implies that the wars that destroyed Saga after its prosperity were the fault of the curse itself in the area.
 * In the case of Kotaro, the curse has been trying to kill him many times trying to drown him in the sea and in the bar where he is, as well as trying to crush him with a figure from Tosu's stadium.
 * Now it makes perfect sense why Sakura was the reason for Sakura's bad luck. It wasn't because SHE was unlucky herself, the curse of the Saga prevented her from succeeding and pursuing her dreams, since then she would have saved the entire Saga, and the universe set out to make sure that didn't happen. And after trying and failing several times to demotivate Sakura, only for her to still not give up, he finally decided that the only way to stop her would be to kill her and according to Arata's files, the truck driver was skewed by a mysterious light and that his truck was pulled by this light towards Sakura. And when Sakura proved physically impossible to kill due to her being a zombie, the curse tried to kill her in an emotional sense by recreating the incident that killed her and gave her amnesia, leading to her losing memories of her time in Franchouchou get depressed again and not wanting to continue. Although thanks to the efforts of her friends, Sakura was able to move on and finally regain her passion for being an idol as well as her memories.

Others

 * Mr. Hibiya, who bought Yugiri and brought her to Saga was the victim of the curse as he was someone very powerful and who could bring prosperity to Saga, he was killed from a "sudden illness".
 * Tae's parents were killed by the physical manifestation of the curse when they planned to bring prosperity to Saga Prefecture. It is unknown how both died.
 * Kiichi's father, who were in the Saga revolt and were killed by the enemy.

Relationship with the Bagua
The curse generates bad luck to those who curse, therefore they even Franchouchou's bad luck coughs were generated by the intentional curse or as a result of their deaths, this is because all the girls died or Butsumetsu on a bad day and therefore the by-product is that in post-life they have bad luck. But the eight girls had extreme bad luck, in Bagua philosophy, going too far to one extreme will take you to the other extreme, so the extreme bad luck of the girls really gives the group great luck to counter the effects of the curse of Saga.

The only people with good luck in the series are Kotaro and Tae, with Kotaro explaining his name change based on the Bagua system which gave him the good luck necessary to prevent Saga's curse from reaching him easily as it did with the girls. Tae for her part is shown in episode 16 that she has good luck to a surprising level since in one day she earned 20 million yen to pay the debt of the girls and Kotaro, so even with that excessive amount of good luck Curse found a way to kill her, surely in a brutal way.
