Yuko Hyodo/History

Chapter 1
Working on the family farm, she asks her brother to allow her to use his tractor to carry the onions and although he refuses but he ends up accepting and takes her to where the onions are kept, her brother asks her about the onions she has stored and Yuko tells him that they are special amulets to protect Eikichi's ordinary life, the latter annoys his brother a lot because he feels incompetent because he feels that he cannot do anything in his life, Yuko comforts him by giving him a raw onion.

During the night she attends with her group to hunt for Sagakos but is visibly weak due to the constant increase of these during the last weeks, after Tae and Anna attack and immobilize the Sagako, Yuko is in charge of purifying it but is attacked unawares by this and she uses all his power to finish it at once, however she says her last words before turning into an onion.

In Eikichi's flashbacks, Yuko always got hurt by her constant struggles and she always excused herself that she was quite clumsy and fell, all this she told her brother to protect him from the shadows.

Chapter 2
During a Tae flashback, a young Yuko is seen defending a battered Tae from a Sagako she was fighting with and trying to protect her as someone she just just met.

Chapter 4
According to Jofuku, Tae and Yuko worked together at the Karatsu Burger food stand and shortly after Yuko's arrival, the place began to rapidly prosper and attract customers, causing Tae to begin to feel better about herself. After she turned herself into an onion, the place began to decompose again until it stagnated.

Chapter 7
Appearing again in flashbakcs, Yuko talks to new member named Anna about joining the team and mentions her not to worry about MJ's wild speech about saving Saga from curses. At a later date she witnesses an argument between Hanako and Tae about how to remove a Sagako from a wall to which Anna quickly finds a solution to the problem.

Chapter 9
At some point in the past, Yuko asks Tae if she believes that the Sagakos were born to do evil since according to her, the Sagakos take the form they do for a reason. The Sagakos appear and take the form of things representing Saga's prosperity, but if the Busters eliminate them without first asking, they will never know the real reason they came to the world and thus stop the base problem.
