And in Chapter 9 Kaoru displays abilities similar to Greed.
Chapter 9: Satomi comes close to an Episode 10 Mami Tomoe freak out. It's probably coincidental that Satomi is also the most developed of the girls, much like Mami was. Probably.
Chapter 12: Kazumi's backstory is more or less identical to Charlotte's Fanon backstory, except Kazumi's wish was used on her grandmother.
Epileptic Trees: As expected, but one in particular needs to be mentioned. (SPOILER TAGS WILL HAVE SPOILERS FOR MADOKA MAGICA). Due to the many inconsistencies with the parent series, it was hypothesized by several fans that Kazumi Magica took place after the events of Madoka Magica. The inconsistencies would be explained by a reality-altering wish that would change the setting. When that actually happened, several fans were quick to claim I Knew It!... except it was just the opposite. The changes introduced at the end of Madoka Magica are incompatible with Kazumi, especially Chapter 3. This was ignored by several fans. For the record, many of the inconsistencies were explained in a different fashion in Chapter 4, and Chapter 5 confirms that Kazumi Magica is set before or during anime events.
Fridge Brilliance: Every magical girl has a wish granted and at least one "bonus" power related to their wish. Satomi wished for the ability to talk to animals. That was her wish, not her power. Of course she would be able to do something else.
To expand on that, the Pleiades' powers seem to stem from the spirit of their wish rather than the words of the wish. Umika's literature related wish allowed her to read minds and rewrite memories. Mirai asked for a museum to house her teddy bears and she can summon a collection of them. Satomi's wish was to speak to animals i.e. communication. Her Phantasma Bisbiglio ability allows her to use someone as a medium to communicate through.
Dunno if this all counts as fridge; it's established in the main anime that a magical girl's powers are related to the wish.
In the series, there are two instances where someone makes an alternate suggestion in response to someone's witch: Jyubey saying Michiru could wish away her comatose grandmother's illness when she wishes for her to simply wake up and Michiru asking why Kaoru doesnt heal her own injury when the latter wishes to hurt the people hurt in her soccer match. In Michiru’s case, she replies that healed her grandmother would go against her grandmother’s beliefs while Kaoru expresses confidence that she’ll eventually go back to playing soccer. Despite this, both girls are later shown to have no regrets and the next panel shows her with her leg healed. In a way Michiru and Kaoru’s wishes could be considered an inverse of Kyoko and Mami from the Madoka series. Kyoko wishing for people to follow her dad essentially brainwashing them when her father wanted people to listen b/c they truly believed and out of their own free will. Mami wishing for herself not to die while neglecting her parents who were already dead but could’ve been saved if she’d wished it too. Fringe Horror comes when you remember that Kyoko’s dad went crazy when he discovered his daughter’s wish which he considered witchcraft and perverting his beliefs and killed himself and the rest of the family afterwards while Mami would suffer Survivor’s guilt from outliving her parents and realizing she could’ve saved them if she had thought about them and not herself. Now consider what would’ve happened if Michiru and/or Kaoru had taken up the alternative suggestions only to regret it afterwards
In one of the flashbacks, the silhouette of the incubator seen with Mami at first seems to be Kyubey, only for the incubator in the flashback to then be shown to be Jubey. However, with Chapter 21 revealing that the Pleiades made Jubey, and one of Umika's spells rewrote the memories of magical girls in the city to view Jubey as the incubator they had contracted with, this means that it likely was Kyubey who really appeared in the flashback. This also explains why Kyubey was partially obscured in the flashback of Airi making her contract.
Then there's the sudden witchifications that take place in the story to the point of a Diabolus ex Machina. Anri, Satomi, Niko, Saki, the Soujus and the gems in the Freezer. Chapter 21 reveals that instead of completely purifying Soul Gems, Juubey could only clean the surface meaning that girls thought that their gems were clean when in reality, they were still dirty hence the constant witchifications. Fridge Horror when you wonder how many Puella Magi turned into witches because they didn't remember to use their Grief Seeds to clean their gems and because the local Incubator Jubey couldn't purify their gems. And judging from all the darkened Soul Gems in the Freezer, probably a lot.
The forming of the Pleides Saints is notably the only time we see a mass contract in the Madoka franchise. Why is this important? Its been shown that the Incubators m.o. is to offer a girl a contract when they are at their lowest emotional point and alone, thereby making them easier to manipulate and ensuing they make short sighted wishes. The Pleides, on the other hand had already gone past the Despair Event Horizon and were more emotionally stable and other people for support when they made their contracts which is why they were clear headed and savvy enough to make wishes that help them with their goals instead of asking for a direct result, allowing them to go on without regrets. The one Pleaides Saint whose wish would bite her back was Nico who kept hers a secret rather than share it with the others; if she had, the others could've told her why it was a bad idea and discouraged her.
Fridge Horror: When Madoka rewrote the universe, she only changed the fact that Magical Girls turn into witches. This means that Kanna Hijiri will still be created in the new universe from Niko Kanna's wish. It might not happen, but the possibility still exists...
On the other hand, the possibility of Kazumi existing in the new universe is definitely nil. Since witches don't exist in the new universe, the Pleiades wouldn't be able to make witch clones of her as they did in the old universe. Plus, the Pleiades would probably be more capable of coping with her death if/when she faded since the Incubators actually warn the girls about that before the contract instead of finding out about their fates as an Awful Truth.
According to Jubey, Kanna was created as a way for Niko to see what her life would have been like if she hadn't accidentally shot her friends when she was a kid. However, doing that meant letting Kanna take her place among her family & friends while Niko would've had to avoid coming into contact with them to keep up the deception. How badly would her psyche been affected by that incident if she was willing to remove herself from everyone she's known just for a glimpse at an alternate life? For that matter, where has Niko been staying while Kanna was substituting for her?
Fridge Logic: How did Yuuri and Souichirou not feel any weight differences between trunks upon bumping into eachother? Clearly, that bomb must've been considerably lighter than Kazumi, or else Kaoru wouldn't have been able to kick it so damn high in the air.
Genius Bonus: The Pleiades Star Cluster is in the Taurus constellation. The constellation after that is Gemini. The villains include Airi, who wished to become Yuuri, the Soujus, who are two magical girls in one body, and Kanna, who was a copy of Niko. The magical girls who fight against the Pleiades' Saints can all be thought of as twins.
There's also the duality of "old" and "new" Kazumi. Especially since the new Kazumi is a clone.
The "Angelica Bears" museum. The Angelica genus of plants contains the Ashitaba plant. It's name literally means "Tomorrow's Leaf". This is apparently a pun on Mirai Wakaba's name, which literally means "Future Young Leaf".
Growing the Beard: Grew some stubble in Chapter 4, and seems to have a full beard in Chapter 5.
Les Yay: There is quite a bit of this. The most obvious "couples" are Umika/Kaoru, Airi/Yuuri, and Ayase/Luca.
Airi/Yuuri: To put it in perspective, Airi became a witch because she was consumed with getting revenge for Yuuri's death. Her witch form is a giant heart. There are also clear parallels between Yuuri's wish for Airi and Sayaka's wish for Kyousuke.
In the Omake comics, Saki seems to feel something special for Kazumi. YMMV on whether or not it's Big Sister Instinct.
Chapter 12 has Saki buying a very sentimental gift for Kazumi, and Mirai feeling jealous of Saki and Kazumi's closeness.
Chapter 13 has Satomi confirm that Saki loves Kazumi.
Chapter 14 clarifies the wording. Saki actually loves (or loved) Michiru, and she likes the clones. She might have been unable to finish them off because they remind her of Michiru.
In Chapter 18, when Saki becomes a witch, Mirai refuses to fight back and ends up decapitated. It's established that she had no problem fighting her friends' witches before (Niko's), but she is unwilling to hurt Saki even when she's a witch.
Moral Event Horizon: No less than three of the Pleiades Saints have crossed it as of Chapter 21. Long story short, when Kyubey (who crossed it in Madoka Magica, mind you) proves to be more trustworthy than you, you know you're past the MEH.
They Wasted a Perfectly Good Plot: The Souju sisters. Unlike the other villains, we never learn their backstory or motivation. What did they wish for? Do they collect soul gems for any particular reason, or are they just Axe-Crazy? Just who are they? They are set up as a real anomaly, being both insane and predatory... then they're defeated and Niko's death ensures that they're promptly forgotten by the plot.
The official translation itself is actually a bit better at translating all the language puns. For example, the first chapter's title was the awkwardly named "Bad-Guy-Reckonoff" in the scanlation. The official English release uses the smoother "Spotabaddynoff".
It also correctly translates the Shout Outs in the Italian attack names - see the main page.
