Back on the highway, Yumiko tries to comfort Magna after witnessing their friend turned into a walker, and also were comforted by Michonne, who confessed that she understood the pain of losing someone she considered part of the family. After spending the night in an abandoned factory and suddenly being ambushed by a pack of walkers, Yumiko claimed her weapons to defend herself and with the use of her bow, she ended up with several walkers that crossed her path making their way to the horses to escape the undead and finding the zombified Bernie among them. When Michonne declared that all the weapons they found from Magna's group would be taken by their group, causing Magna to become hostile as she is against the woman's decision, Yumiko became the voice of reason in the middle of the discussion and proposed to her entire group to accept Michonne's terms instead of starting a fight.
In " Stradivarius", as they made their way to the Hilltop, Yumiko and the rest of her group made a stop at the place where they were attacked by the herd of walkers and took advantage of the moment to collect all their stuff that they had left behind when they escaped from the herd - among them Bernie's belongings - with which Yumiko tried to convince Magna to take them as a souvenir to her late friend. However, after a sudden change of mind, Michonne decided to escort Yumiko and the rest of her group to another community where they would be safe instead of sending them back in the open, and decided to escort them to another community they knew.
Once she regained her consciousness the next morning with the news that they were leaving the community, Yumiko joked with her group stating that she could have hit her head harder to stay longer in the community. Although her injuries were healing and stabilized, Yumiko did not wake up from her deep sleep while being visited by the rest of her group and because she was the only one in the team not to be stripped of her weapons, Magna took her necklace with a sharp blade as a defense weapon against any threat that arises. In " Who Are You Now?", after meeting the rest of Judith's group and being escorted to Alexandria, Yumiko was quickly taken to the infirmary of the place so that her wounds could be treated by Siddiq. Making their way through the wood, a wound Yumiko is carried by her friends inside the forest and discovered a little girl who had rescued them she later introduced herself as Judith Grimes. Yumiko, like the rest of her group, defended themselves from the walkers while trying to escape, hurts her head and the group overwhelmed with Yumiko out of combat the group can hardly keep fighting and although they ended up being surrounded by them and subsequently rescued by an unknown person. Yumiko appears for the first time in " What Comes After" while escaping from a herd of walkers. ĭuring the war against the Whisperers, like Magna, Yumiko was a very important member of the militia, helping them win the war against the Whisperers and, after the death of Rick, Yumiko and her girlfriend Magna live together in the Commonwealth. They find Negan, who tells them that Rick and his people are animals that torture him and begs them to release him, but Magna refused as she knew that Negan was lying. When Rick is absent in Alexandria, Yumiko and the group discover a prison. Īfter being rescued and taken to Alexandria, Yumiko and her group were interviewed by Rick and Andrea in order to allow them to stay, and although at first they felt comfortable with the community they soon began to distrust the idyllic life they led. As they moved through the east side of Washington, a massive herd of walkers that was being routed by Jesus and other residents of Alexandria took Magna's group by surprise, causing them to lose their trailer and other belongings, as well as one of its members. At the beginning of the apocalypse, Yumiko is one of many survivors who arrive at a nursing home near Washington D.C. Yumiko is part of a group of survivors from Richmond who joins the Alexandria Safe-Zone two years after the fall of Negan and the Saviors.
