These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Yuma is either viewed as The Woobie and Kyouko's necessary surrogate sister/adopted daughter, or a Bratty Half-Pint who should have been cut out of the story. While her situation is undoubtedly horrible, whether you find her cute seems to vary from person to person. Her Rousing Speech is either her crowning moment or bizarrely out-of-character.
Just how justified Oriko was in her actions remains a topic of debate, particularly given that she's viewed as something of a martyr by people who dislike Homura. Her portrayal in fanfic varies between A Lighter Shade of Grey to a cackling murderer. Her design gets some of this as well; some find the Pimped-Out Dress and Nice Hat to be probably the most beautiful outfit of any series, others think it looks silly and refer to her as "buckethead."
Kirika is either Crazy Awesome and a great deconstruction of the Manic Pixie Dream Girl, or a pile of Wangst who's nuts for no good reason. Her relationship with Oriko was either one of the best-explored romantic relationships of the series or really, really creepy (though few would call it a very healthy one).
Better Than Canon: Girls and the End of the World is fantastically well-drawn and condenses the events of the manga into the core conflict between Homura's selfish love and Oriko's selfless hatred. Many people are surprised when they see pictures of it and find it's not from the actual series.
Counterpart Comparison: A number of of people have found that Oriko, Kirika, and Yuma resemble various Touhou characters; for example, Yuma has been noted to look like Kisume and the common depiction of Daiyousei. Meanwhile, Kirika has a number of similarities to Renko Usami, while Oriko is much like Marbiel Hearn and Yukari Yakumo. The artist of Oriko Magica has drawn Touhou fanart.
Many mistook Kirika for Sayaka in untranslated preview images.
And Oriko's weapon resembles Reimu's Hakurei Ying-Yang orbs, or Marisa's Orreries Sun.
Draco in Leather Pants: Following Rebellion, "ORIKO WAS RIGHT" ended up becoming something of a meme. (Even though it doesn't really make sense. Oriko was trying to kill Madoka (who quite literally made the world a better place in the anime) while viewing Homura only as an obstacle to that goal.)
Epileptic Trees: Started the very moment the cover was revealed. The major topics were about when Oriko Magica takes place, and whether the new magical girls introduced in Oriko Magicawould become witches that were seen in the anime.
Fandom Rivalry: Though some fans happily accept both, people who liked Puella Magi Kazumi Magica seem to hate Oriko, and vice versa, given that they're very different takes. Fans of the former call the latter an ugly, pointless, meandering sidestory that does nothing new and borders on unreadability, versus a lengthy and detailed narrative with great art and tons of characters that stands on its own. Fans of the latter call the former a skeevy, character-overstuffed, overlong piece of pap that reads like a mix of a Dolled-Up Installment and a bad fanfic, versus a dark and deconstructive tale that introduces the best Canon Foreigners of the franchise and makes great use of the original material.
Of course, there are also those who think both series are equally inferior to the anime.
"Funny Aneurysm" Moment: In a flashback, after a young Oriko pledges her efforts to help her father, he offers her a reward, and she says, "Daddy, you can't give out bribes!", to which he laughs and says she "got (him) there". Taking money that doesn't belong to him, on the other hand...
Harsher in Hindsight/Hilarious in Hindsight: Quite a bit of things from Oriko are reminiscent of things from Puella Magi Madoka Magica The Movie: Rebellion, even though it's probably coincidental. The things include *WARNING REBELLION SPOILERS* a witch barrier being created before the magical girl becomes a witch, Homura's insistence on saving Madoka against her wishes, and almost everythingabout Kirika Kure. Finally there's the matter of Oriko's vision at the start of the series. While it's supposed to be Madoka's witch, it doesn't look much like Walpurgisnacht or Gretchen. It looks more like a black human figure in a dress, with long hair and/or wings...
It is human emotion that created the gods and created the demons.
Heartwarming In Hindsight; Mami and Kyouko's interactions in Oriko Magica can be seen as this after listening to the 3rd CD Drama and/or reading The Different Story spinoff. Despite their partnership ending sourly in the past, the two manage to interact in civil terms, in contrast to The Different Story and the PSP Portable game where their reunion was more hostile. When Mami meets up with Kyouko, she warns her about the Magical Girl killings and Kyouko doesnt hesitate to bail Mami out when Oriko and Kirika had taken over the school. Then there's their victory fight against Witch!Kirika which is more poignant if you consider this is their first witch fight together in a long while.
I Am Not Shazam: Oriko, one of the main villains in the manga is often confused with Yuma, the little girl with green pigtails who appears of the cover of the first volume.
Les Yay: Oriko and Kirika, who value each other above anyone else.
Not to mention Kirika's wish was to change her personality just so Oriko would like her more.
This quote confirms it:
Kirika: Treating me like a child again! Really Oriko, I-
Oriko: "… Hate you"?
Kirika: I love you!
This, combined with Foe Yay, undertones Mami and Kirika's relationship.
Arguably, also her murder of Madoka. In this particular timeline, everyone had learned the Awful Truth yet thanks to Yuma they managed to not fall into despair, so making Madoka swear off becoming a Magical Girl would've been reasonably easy and the girls would be Genre Savvy enough to not become witches. There was no need to kill Madoka anymore - and yet Oriko still did it. Likely just to spite Homura over her own death, rather than anything else.
Even worse is the fact that the Walpurgis Night is still around, which has shown to be unstoppable except for Madoka whose the only one with the potential to defeat it. It's possible that Madoka would still become a magical girl after learning of the Awful Truth, but it's not far-fetched to say she'll likely make the same wish she did at the end of the anime. In her own self-righteousness, Oriko thinks she has saved the city, but in reality she actually has doomed it because she has killed the only one who can defeat the Walpurgis Night.
Narm: Due to the art-style, some things are really hard to take seriously. For example, Yuma just saw her parents killed right in front of her, and she's wondering where she's going to go. It's a really sad scene, until...she makes this face (bottom right panel.)
Goddamnit, Madoka! You just saw your teacher being eaten alive, the witch familiars are attacking everyone, and you've just been separated from your friends. DON'T MAKE THAT CUTESY FACE! (bottom left)
The scene of Kazuko-sensei being chomped by a Witch in chapter 5.
Offscreen Moment of Awesome: After the Rousing Speech by Yuma, Mami promised that they will make Kyubey pay for tricking them after they beat Oriko. But then Homura rewinds time before that happened because Madoka died. God damn it, Homura.
Tear Jerker:Madoka's death. Even though it was a Foregone Conclusion due to this being a previous timeline, the last scenes had set up a Hope Spot for her survival. Also while in other timelines, only Homura was there to set her death, here we get an audience from Sayaka, Hitomi, Mami, Kyoko and Yuma. To make things more depressing, Word of God states that Homura can only turn back time after a month has passed from her discharge from the hospital, meaning that she had to dwell on her failure to save Madoka in this timeline for days or weeks.
Kyouko's thoughts as she thinks she's about to get killed, regretting that "it sure was a rough life" and wishing she could have had a good dream once. Her being neither happy with her life nor able to accept her own death is quite depressing.
Uncanny Valley: Since its unchanging smile is harder to convey in the manga, Kyuubey is instead drawn with something more like Fish Eyes, taking it from unnaturally cute to just plain deformed-looking.
The Woobie: Yuma. Poor kid deserves a lot of hugs and comforting for all the trauma she's been through even before the story began.
It's hard not to feel a twinge of sympathy for Oriko when we see a flashback of her sitting all alone in a corner of her vandalized house, wrapped up in a bedsheet with teary eyes after her father, a politician, committed suicide after it's revealed that he was embezzling funds. Everyone turns against Oriko, leaving her completely alone (which is bad enough in and of itself, but it also implies that the only reason they hung around her was because of who her father was). Cue Kyubey's entrance.
