Sagako

Sagako are malevolent demons featured exclusively in the spin-off manga, Zombie Land Saga Gaiden: The First Zombie.

In 1989, the curse of Saga is embodied in the physical forms of different demons who manipulate and terrorize the residents of Saga. Although all sagako are antagonistic to the prosperity of Saga, the exact manifestation of each individual demon varies in appearance and method. As such, the Saga Sagako Busters individually track, fight, and purify sagako. The purification process is performed by sealing the sagako within an onion grown from Saga soil.

Abilities

 * Element Manipulation - The Sagakos are able to control the elements in the places where they appeared and use them both in defense and attack.
 * Resistance - More specifically to conventional low caliber ammunition.
 * Limb Extension - Limbs can be extended at will but this depends on the type of Sagako.
 * Reality manipulation - It also depends on the location, but they are able to distort reality to their liking.
 * They are also capable of manipulating people's emotions so that they fall under their control.

Weaknesses

 * Onions - Yes, some insignificant onions that are the main crop of Saga Prefecture are capable of defeating demonic entities by sealing or weakening them.

Trivia

 * The curses and kami Sagako Busters fight like the matsunokami (pine kami). In general, the kami are neither good nor bad; they have a somewhat unique existence in Japanese culture as the intangible spirit of everything in nature (further reading). Without that kind of cultural awareness, I think it makes this series look a lot more like Ghostbusters than it really is.
 * They went to Ureshino's hotel from ep 4.
 * Saga is using agriculture to fight demons.
 * Farmers' tools like shovels could also be the same.
 * Onions, one of Saga's great crops, have anti-evil properties.
 * Onions can talk too.
