Hyodo Farm Onions

Hyodo Farm Onions (兵頭農園の玉ねぎ, Hyōdō nōen no tamanegi) are the means of containing the Sagakos that manifest in Saga. They are the onions naturally grown by the Hyodo Family in their titular farm.

Description
The onions from this farm have the particularity of serving as a means to seal the Sagakos and people inside them. The land of the Hyodo farm is special; long exposure to love, gave earth the strength and power to seal curses through Saga's Prosperity. Without this power, Sagako could not be sealed and purified.

They are used by the Saga Sagako Busters to seal the Sagakos. The Hyodo twins are the only ones with the power to seal through onions, and that's why they are so important to the team. The onions on this farm have their own and collective consciousness and can communicate with people who have been blessed with prosperity.

Uses
Sagako's purification is done through the Hyodo twins, who were blessed with Saga's prosperity and have the power to seal these curses. The purification power is executed by casting the onions to the curses, sealing them within them with a seal. Not only that, but even after being sealed, lovingly cared for onions can pass the feelings of the sealer to the souls of the Sagako, and perhaps, be able to communicate with them.

Being a Saga crop, different dishes can be prepared using onions without losing their special properties. Even crushed, cut, and cooked, they still retain the power of prosperity and are capable of sealing Sagakos.

Onions can act as incubators for the Sagakos within them. When the Busters' mansion is destroyed, the onions miraculously emerge from the rubble intact. This allowed Eikichi to put a curtain in the house as a blanket for them, since for him, onions are like his children. Thanks to this action, the Sagakos that were inside the onions are freed, already purified, and they meet Anna and Hanako for the battle with Magatsuhi.



Yuko's onion goes through a similar process when Eikichi uses his Misogi power when talking to Tae, which triggers Yuko's onion to pass its power to Eikichi, who passes it to Tae by hugging her.

Tae, who now has the purification power of onions in her own body, goes to Magatsuhi and purifies her. After being defeated and Tae fused with Magatsuhi, the power of the onions wears off; they are no longer needed. Since all the curses in Saga were sealed, the seals on the onions are broken and Yuko is released from the onion where she was, with the particularity of merging with the Sagako that was inside the onion.

Abilities

 * Sealing of the Curse—Love in their lands made Saga's prosperity bless this farm and its main crop: onions. With Saga's prosperity in their favor, this magical power is powerful enough individually to seal powerful curses capable of ending people's lives just by manifesting in a specific area. Although the number of onions varies depending on the power of the wielder, they seem to be willing to give their lives to save Saga.
 * Human Containment—While they can seal curses, they have been seen to seal humans when their misogi power is weak, and they are about to die. Yuko Hyodo is one of the humans who contained herself inside one of these onions to be revived later.
 * Power Transfer—As a final measure to fight the curse, Yuko's onion passes the power of purification to Eikichi and Tae, causing both of them to glow when received. The power of purification remains, but the only thing that changes is the container, which is now the body of the bearer of this power.
 * Telepathy—Although it seems crazy, these onions have their own consciousness and can talk to the Hyodo twins to give them important clues. In crowds, they are more than willing to give their lives to seal the Sagakos that threaten Saga.

Trivia
