Magia Record Mirrors Story
Layer 1
Iroha Tamaki enters a pitch black place that suddenly lights up. She says the place feels like a witch's mansion. In a flashback, Iroha gets an invitation from a witch's familiar, which shoots it at her. The invitation says in bad handwriting: "We invite you to the mansion and will welcome you with open arms" with a map to a location named "Mirror Mansion". Back in the present, Iroha finds Mitama Yakumo is at the mansion. Mitama explains she wasn't invited, she just came there on her own. Iroha asks what the mansion is. She notes the mansion is empty save for two large mirrors facing each other. Mitama thinks about how to explain things, but then pauses. She tells Iroha to be careful, and that she doesn't fight so she can't with Iroha. When Iroha asks her to explain, Mitama says it's like a ritual and Iroha should be fine. After she tells Iroha to have a good time, a familiar appears and throws Iroha into a barrier. When Iroha wakes up she sees a copy of herself. The other Iroha laughs and attacks.
Layer 2
After beating her duplicate, runs away and finds herself in the mansion's entrance. Mitama explains Iroha was in the barrier for five hours before going into more detail about the mansion, which she calls it the "Mansion of the Mirror Witch". She says the mansion belongs to a witch that delibrately invites magical girls inside, like a venus flytrap. She points to one of the mirrors and explains Iroha came out of it. Inside the mirror are the layers of the Mirror Witch's barrier. Mitama explains that the barrier has many layers that compose it, and it is nicknamed "The Mirrors Without End". Mitama says the Mirror Witch lies at the end of the barrier, but admits it's something like a rumor.
Mitama then tells Iroha that the barrier is populated by replicas. She said that when Iroha was first attacked in the mansion the familiar took her form to be copied. These copies are initially weak, but as time goes by, the witch can make more powerful copies. Iroha tells Mitama that she already fought her duplicate. Mitama says that it's alright; the witch has copies of every magical girl that came to the mansion, and that the copies are only magical duplicates. She tells Iroha to be careful since the copies may be of people she knows. Iroha decides to prepare herself to fight the Mirror Witch. Mitama tells Iroha that the Mirror Witch has some kind of hidden secret that relates to Kamihama City. (She also tells Iroha she's there because the enemies drop "Mirror Coins" which she buys from magical girls). Iroha goes into the barrier, with Mitama's encouragement.
Layer 3
After entering the barrier, Iroha finds Kaede Akino yelling at herself. Iroha quickly identifies the duplicate, as it's telling the real Kaede that she's a loser. Iroha intervenes when the fake Kaede tries to attack the real one. However, she's unable to attack the fake Kaede, even though she knows it's not the real one. The fake attacks, but is stopped by Yachiyo Nanami. Yachiyo tells Iroha to defeat the fake and move forward.
Layer 4
After the false Kaede is defeated, Yachiyo says the real one has some stress built up. Kaede insists she's nothing like the copy and asks Yachiyo what she's doing here. Yachiyo says she sometimes comes to the Mirror Witch's barrier to investigate, and came across the girls via coincidence. Iroha reveals why she came into the barrier. Kaede reveals that she came in with Momoko Togame and Rena Minami, but got separated. Kaede also reveals this is only their second time in the barrier. Iroha wonders if they are all free to come and leave the barrier as they please. Yachiyo explains that the barrier constantly changes although if you track your own magical energy you can come back to a place you've been to. The group decides to return to Mitama.
Layer 5
Mitama claims she hasn't seen Momoko or Rena leave. Yachiyo admits she can't even be sure they're still in the barrier, due to the strangeness of the place. Iroha asks Mitama why they're allowed to leave the barrier, even though the Mirror Witch supposedly wants to devour them. Mitama says there have been magical girls who don't come back, and the entire setup is to encourage magical girls to go farther than they're prepared for. Yachiyo thinks the witch is ill-mannered. Mitama reassures Kaede that Momoko and Rena are fine. The group head into the barrier to find Momoko and Rena. Iroha wonders if this is the Mirror Witch's plan
Layer 6
While looking for Momoko and Rena, the girls spot someone standing in front of a mirror. The girls tells herself that she is the most beautiful person today too. Sensing the group, she recognizes Yachiyo on sight and introduces herself as Ria Ami. Ria claims to be Yachiyo's rival, but Yachiyo barely remembers who she is. Ria also claims she isn't a Mirror duplicate. Kaede is scared by Ria's exuberance, but Yachiyo says her bark is worse than her bite (probably). Yachiyo asks if Ria is here by herself. Ria says she can handle the barrier alone, unwilling to admit her schedule didn't line up with anyone else's. Kaede still thinks Ria's not real. RIa claims she can't forgive those fakes for duplicating (though she does understand why they would copy her beauty). She poses in front of the mirror, saying a fake couldn't be this beautiful. Iroha can't tell the difference. Seeing something shine, Yachiyo tells Ria to stop facing the mirror. Ria blows her off. Suddenly Yachiyo disappears. Ria wonders if she's responsible.
Layer 7
As Iroha and Kaede tried to understand what happened, Ria excliams she didn't do it on purpose. She says she only tried to show Yachiyo the mirror with Ria's own reflection, and believes that triggered Yachiyo's disappearance. She insists it's an accident. Kaede is disheartened but Iroha reassures her. The two leave, but are stopped by Ria who says she wants to help. Iroha says Ria doesn't have to go out of her way, but Ria says she has a bit of time. She still insists she did nothing wrong. Iroha accepts Ria's offer. Ria leaves to go searching and tells the other girls to follow her.
Layer 8
Yachiyo is alive, and still in the barrier. She still can't remember Ria's name. Suddenly she runs into Momoko. Yachiyo says she was looking for her. Momoko immediately attacks, claiming Yachiyo is a fake. She says the real Yachiyo wouldn't say something "that twisted". Yachiyo tries to talk, but Momoko refuses to listen. Suddenly another Yachiyo arrives, and commands Momoko to be pierced by her lance. She says tells Momoko to hurry, as she wants to pierce her.
The real Yachiyo wonders if this is a joke, and says this is the first time she's seen a replica like that. Yachiyo quickly realizes that Momoko had met that replica and attacked the real Yachiyo by mistake. Momoko is embarrassed that the real Yachiyo saw a bad side of her. Yachiyo asks Momoko what she really thinks of her, but Momoko pretends not to listen. The false Yachiyo asks them what they're doing, and is promptly destroyed by the real Yachiyo and Momoko. The two prepare to fight other replicas.
