One of the many timelines Homura created. Kriemhild Gretchen's potential for destruction has reached a point where it changes Oriko's destiny.[1][2] It is depicted in:
At an unknown point in time, after her father committed suicide, Oriko Mikuni makes a contract with Kyubey, to know the reason why she's alive and gets the power to see the future. She tests her power for the first time and sees a vision of Mitakihara being destroyed by Kriemhild Gretchen. She distracts Kyubey by telling him of Yuma Chitose's potential to become a Magical Girl and oversells her power.
Oriko is attacked by a Witch and Komaki Asako saves her, revealing she is also a Magical Girl. Oriko pretends not to be a Magical Girl and after Komaki and Kyubey leave, she is attacked by Kirika, who reveals she doesn't remember what her wish was. Oriko manages to ambush Kirika and knock her down. Oriko introduces herself and offers to share the truth about Magical Girls if Kirika becomes her ally.
In Kazamino, Yuma and her parents are caught in a Witch's Barrier and Kyoko manages to rescue her. Yuma becomes attached to Kyoko and, when Kyubey approaches Yuma for a contract, Kyoko stops him and takes Yuma under her wing. The two go to a hotel to spend the night.
Oriko orders Kirika to attack Magical Girls and gather Grief Seeds for her. Komaki's friend, Akira meets Koito, Komaki's younger sister, who suspects Komaki is sneaking out for late-night parties. Akira is doubtful but decides to investigate.
Sasa Yuuki has made a contract to be able to brainwash others and controls the Witches of Kazamino to cause many deaths. Lina Hitomi's team has lost their friend, Futaba, while chasing Sasa.
Komaki defeats a Witch and then encounters Kirika, who challenges her. Akira tracks Komaki using a phone app and finds her fighting Kirika as a Magical Girl instead of partying. During the fight, Akira panics and accidentally calls Koito while trying to reach the police. As Kirika moves to kill Komaki, Akira rushes in and is fatally struck, dying in Komaki’s arms. Kirika realizes she has accidentally killed a bystander and then accidentally kills Komaki too. As she's dying, Kyubey visits her and Komaki warns him of a Magical Girl dressed in black.
Kyubey tells Oriko about a Magical Girl and a normal girl who were murdered. Oriko realizes Kirika is responsible. Elsewhere, Sasa Yuuki arrives in Mitakihara, amused by rumors of a Magical Girl murdering others, and hopes to tame her to clean up the town.
Lina Hitomi's team fight Sasa, who pretends to surrender and then escapes.
Oriko attends Komaki and Akira's memorial with Miyuki. Afterward, Oriko meets Kirika and tells her to focus on the future. This causes Kirika to remember her wish and Oriko gets a vision.
Sasa fights Mio, but she is killed by Kirika and Sasa realizes Kirika is the rumored Magical Girl murderer and tries to escape. Oriko arrives and tells Sasa to listen. Lina's group finds Mio's corpse and vows to stop Sasa to prevent more sacrifices. Sasa, meanwhile, lies to Oriko and Kirika about her past, claiming Lina's group unfairly attacked her. Lina, Mai, and Miyako note police activity over Komaki and Akira’s murders, and Lina suspects someone in Mitakihara is as dangerous as Sasa.
Sasa uses her Witches to track Lina’s group with Kirika’s reluctant help. Oriko has a vision of the world’s end and identifies Homura Akemi as Madoka's protector.
Lina and her group meet Kyubey, who warns them to be careful in Mitakihara and updates them about Kazamino being protected by another Magical Girl. Lina decides they need a new plan and they return to their room.
Sasa and Kirika track Lina's group and later, Kirika bursts into Lina’s room. From a distance, Sasa watches and Oriko reassures her that the surprise attack will reveal a weakness to exploit. Meanwhile, Madoka becomes lost in the same Labyrinth as them.
Sasa joins Kirika with a Witch under her control. As they fight, Oriko tries to talk to Miyako and reveals her wish to save the world. Lina defeats Sasa and Mai arrives to finish her off, but Oriko stops her. Miyako questions Lina's actions and accuses Lina of causing harm and indirectly causing Futaba's death. This causes Lina to transform into a Witch.
Miyako is decapitated by Lina, the girls defeat the Witch and Kirika kills Mai. Oriko and Kirika leave as Sasa rants. Madoka appears behind her and Sasa sends her Witch after her. Madoka then faints, but Homura uses a bomb to kill them and saves Madoka.
Oriko and Kirika go to Kazamino and indirectly help Yuma steal a pocky. After Kyoko defeats a Witch, Yuma gives it to her as a gift. As they head back, Kyubey follows them.
Oriko and Kirika find Sasa’s secret base and find her stash of Grief Seeds. Oriko is tormented by visions of Yuma being attacked by Cecil and quickly leaves. Kyoko and Yuma have a playful fight and fall asleep, over a pillow, unaware that the Witch from Oriko’s vision is near.
Kyoko wakes up sensing a Witch and goes to fight her. Yuma wakes up to find Oriko instead of Kyoko, who tells her Kyoko might be dead. Yuma panics and asks Oriko if she knows where Kyoko is, but Oriko challenges her. Yuma runs to the park to find Kyoko. Kirika finds Oriko and Yuma declares she’ll fight and change for herself for her. Oriko convinces Yuma to become a Magical Girl to save Kyoko. Yuma makes a contract and heals Kyoko. Oriko and Kirika leave and when Kyoko finds out Yuma became a Magical Girl, chastises her.
Day 15 - Tuesday, the 30th: Mami barely defeats Charlotte and senses another Magical Girl, who turns out to be dead. Kyubey tells Mami that there's a Magical Girl killer.
Kirika kills another Magical Girl in a Witch’s Barrier, glad that the girl won’t turn into a Witch. In a diner, Mami reads about unexplained deaths of junior high girls and is concerned about Magical Girl disappearances in Kazamino. Kyubey warns her that a Magical Girl may be targeting others, and Mami agrees to investigate. Yuma approaches Mami offering help for her headache, and Kyoko shows up, surprising them both.
Meanwhile, Kirika talks to Kyubey and denies knowing anything about the killings.
Oriko meets Koito and assures her that she isn’t at fault for Komaki's death. Koito apologizes for her feelings and thanks Oriko for her support.
Madoka talks to Sayaka about her strange dreams and unknown encounters with Witches. Mami approaches Homura, but Homura responds coldly. Later, Homura fights Chika Masumi, who mistakes her for the Magical Girl killer and Homura uses her time manipulation to escape.
Kirika finds an old notebook belonging to Oriko's father and after reading it, declares Hisaomi an enemy of Oriko.
Chika tells Kyubey about her encounter with Homura. He plans to recruit more girls, including Chika, Kirika, and Oriko. Kyoko is uninterested until she learns about Oriko, and decides to help to meet her. Kyubey asks Oriko for help in hunting the Magical Girl dressed in black. He reveals that he thinks it’s Homura Akemi.
Kirika treasures the bunny charm from Oriko, but drops it when a woman bumps into her. Mami notices and helps her find her charm. When Mami mentions a crush, Kirika gets angry, saying that what she feels for Oriko is only love. A Witch appears, and Mami tries to avoid harming Kirika. However, Kirika transforms into the Magical Girl clad in black, who'd been killing other Magical Girls, and attacks Mami. Kirika uses her magic to make the Labyrinth not fade away so she can kill Mami. Mami sets a trap using what she learned of Kirika’s slowdown magic. Mami manages to successfully harm and crack Kirika's Soul Gem, but Oriko, having seen a vision, intervenes and takes Kirika away.
Kyoko and Yuma meet Kyubey, frustrated by the absence of Mami and Oriko. Mami arrives and explains her battle with Kirika and Oriko. At Oriko’s house, Kirika confesses her true feelings and how she wanted to change herself for Oriko, and Kyubey granted her wish, turning her into the person Oriko knows. Oriko demands Kirika make up for her actions, while Kirika agrees. After tending to Kirika’s wounds, she reads the notebook and finds out about Yaegashi manipulating her father into taking the fall for political reasons.
Kyoko and Mami discuss their plans and Mami reveals that Homura is not the murderer, but rather Oriko and Kirika. Chika, late to the meeting, meets Oriko, who kills her with an orb after a brief conversation. Oriko goes to confront Yaegashi and is about to attack him, but he insists that her father's death was caused by her own actions. Later, Oriko returns home and breaks down mentally over the revelations. Kirika insists that she will help Oriko hold on to who she is and promises to help fulfill her wish, as Oriko’s wish has been granted through Kirika’s own.
Kyoko, Mami, and Yuma break into the Mikuni Estate to stop Oriko and Kirika. They cautiously explore and realize Oriko might be using some form of prediction-related power. They only find a bloodied nail as Oriko and Kirika aren't there and instead are playing video games at Kirika's house. Later, Oriko's confronted by a delusion of her younger self, but admits to her own selfishness. Kirika agrees, and the illusion fades.
Oriko visits her uncle Kimihide, discusses her estate with him and confesses on hating him and his aunt. Afterwards, Oriko meets up with Kirika. Kyoko insists that Yuma promises her that if she says "run," Yuma will. Kyubey then arrives and informs them that Oriko and Kirika are near the school.
Kirika forms a Labyrinth around the school and traps everyone inside. Elsewhere, Koito receives a message about the chaos at school and recognizes Oriko in the picture sent to her. Madoka is surrounded by Familiars, but is saved by Homura, and Mami is captured by the Labyrinth and is saved by Kyoko and Yuma.
At the Barrier’s center, Homura confronts Oriko and Kirika. Oriko reveals she plans to kill Madoka to prevent her from becoming a Witch capable of destroying the world. Kyoko, Mami, and Yuma arrive, but Kyoko focuses on defeating Oriko. Kirika's magic is about to run out and can't slow her transformation into a Witch anymore, so she lets go and fully transforms into Latria.
Mami, Kyoko and Yuma battle Kirika while Homura battles Oriko. Sayaka and Hitomi fight Familiars in a Barrier, and they find Madoka. Mami and Kyoko are injured by Kirika and refuse to let Yuma heal them, preferring to die than turn into Witches. Yuma, determined to live, heals them regardless, manages to convince them to keep fighting, and together they defeat Kirika. Oriko attacks again, but Homura warns her she'll run out of magic. Kyubey appears, revealing Oriko’s plans and her failure. He has found Madoka.
Koito, searching for Oriko, meets Miyuki and Kimihide, who are also trying to find her. Madoka, Sayaka and Hitomi head towards where Madoka thinks Homura is. Oriko is killed by Homura, but as she dies, she hurls a piece of Kirika's Witch form at Kyubey, killing him. Homura, after speaking to Mami, Kyoko, and Yuma, finds that the projectile Oriko threw wasn't meant for Kyubey, but rather Madoka. Yuma explains that Madoka is already dead, so she can't heal her.
Koito makes a contract with Kyubey so she can find out the truth about everyone's deaths and gains the power to detect lies that people tell. Afterwards, she joins Mami, Kyoko and Yuma and the four fight Witches together.
Day 32 - Friday, the 16th: When Walpurgisnacht arrives, Mami, Kyoko, Yuma and Koito prepare to fight against it and presumably fail.
In what might be a sort of afterlife or mind-space, Kirika encounters Oriko, who can't walk due to the burden of her actions. Kirika offers to help her by carrying half of it, and the two walk off hand in hand, smiling.
What happens to Oriko, Kirika and Yuma in future timelines is unknown. It can be surmised that Homura preemptively kills Oriko and Kirika early in the timeline to prevent them from causing trouble. On the other hand, Yuma is likely killed by her mother just like in Oriko's prediction in Puella Magi Oriko Magica: [extra story].
