Jofuku

"“They’ve been doing your reckless orders and have been overcoming every obstacle. Including the reckless stuff that even you found impossible. Which, isn’t wrong, in my opinion. And besides, it all started with your ego to begin with. Therefore, you have to end it with your ego, as well.”"

Xu Fu (徐福 Jofuku) is the court sorcerer of Qin Shi Huang, who was ordered by his chief to search for an "elixir of the immortals" on the top of the mythical Mount Penglai. His appearances in Zombie Land Saga have been as the bartender Kotaro frequents and as Kiichi's grandfather, his immortality power also depends on Saga's status.

Present
Currently he works in an unknown bar in the center of the city of Saga, he wears a typical waiter suit and his hair is totally gray and he has a mane that reaches below his neck, he is also partially bald.

It was Meiji
In the Meiji era, his power was reduced and he looked much older than usual, so he was bald and only wore a white robe and a cane to support himself because his back was weak.

Personality
From what little we know about him, he is a mature man who is not afraid to talk to people and is direct with his conversations, although he likes to play a bit to be cryptic with them too, during his appearances during the series he is direct with Kotaro calling his plan insane but worrying that Yugiri is okay. In episode 13 and the first of the second season this attitude goes a little further by insulting Kotaro for his vagabond appearance and purposely mistaking Franchouchou's name for "Saga ettes" in reference to the stadium where they failed, in addition to intentionally provoking Kotaro with telling him to tell the girls that it's over for them, so that he comes out of his depression and goes directly to save the group.

During the Meiji era, his power was greatly reduced by the existence of Saga on the map, so he hysterically looked for a young man to help him, this young man is Kiichi and with the advice of his grandfather he tries to return Saga to the place he was before. During his appearance in episode 21 he is seen as a grumpy old man who seems to be insane by yelling that he is Saga himself.

Trivia

 * He is the very court magician of Qin Shi Huang Xu Fu, who was ordered by his chief to search for an "elixir of the immortals" on the top of the mythical Mount Penglai. He found the elixir whose name is "Furofuki" on the top of Mount Kinryu after reaching Saga and meeting the locals, indicating that the island he was looking for is actually Saga Prefecture, the elixir It was given by a leading magician of the 8 immortals Anqi sheng, this place is known in Chinese mythology as the place where fruits grow that give immortality and are capable of reviving the dead, strongly indicating that this is the reason why which the girls were revived.
 * The bartender is Xu Fu or Jofuku himself, who achieved immortality by becoming Saga's kami. Therefore, he says that he is Saga, and his power, appearance, and intellect decreased with Saga's removal from the map. If Yugiri helped restore Saga's name, then she saved him and would explain why she owes him so much.
 * Xu Fu becoming Saga's kami caused some disturbances to the supernatural power in Saga, giving birth to the demons called Sagako that Tae fought with in Zombie Land Saga Gaiden.
 * Since Xu Fu is Saga's kami, and Tae Yamada is an active exorcist in Saga, Tae and Xu Fu probably know each other, hence their inclusion in the idol group.
 * The images posted in the bar foreshadowed that the association is quite intentional in this Universe, and as confirmed in the credits of episode 20 it is about Xu Fu himself.
 * Both images in the background of the bar belong to the Jofuku Chojukan, the museum and park dedicated to the legends of xu-fu in Saga.


 * The "Genkai Zombie Energy Park Project" that he mention in season two is probably a reference to Genkai Energy Park, which is a kind of park in Saga adjacent to a power plant with some exhibits and assorted things.
 * Xu Fu has the power of divination, as he predicted that Saga would lose his name. He also correctly predicted that some orphan he collected would eventually save Saga (because Saga still exists). Therefore, it is very likely that he chooses all the girls through divination and resurrects them, reinforcing the Bagua theory.
