YMMV / I=MGCM

• Accidental Innuendo: The magic beads/orbs (both SR and UR rarity) have pointed filigree ends on the top and the bottom, and lewder-minded players occasionally suggest they resemble butt plugs, insertable beads or packed condoms.
• Angst? What Angst?:
  • Though Cocoa lost her mother to an infectious disease in her childhood, she manages to remain cheerful and consummately life-loving. It's made particularly remarkable by her having to effectively take on her late mother's responsibilites around the home, including minding and helping raise her two little brothers, while still having to live her own life, and the immense strain this places upon her. Even when crises arise at her home, she maintains a jovial attitude and is only liable to break down in the worst situations.
  • This contrasts her Odd Couple best friend Seira, who lost her beloved and admired older sister in a sudden car accident a few years prior and has coiled in on herself in order to Never Be Hurt Again. One of the main reasons they stick close is Seira's warm acceptance of Cocoa's efforts to defrost her and help her find new joy in life - yet again underlining just how much of an anti-angst powerhouse Cocoa is.
• Alternative Character Interpretation:
  • Is Tobio a teenage amnesiac Chivalrous Pervert or an almost-Celibate Hero?
  • Is Vivian The Man Behind the Man of 2nd arc main story, or she's just a villainous witch who has Blue-and-Orange Morality?
  • Is Kamisaman a Manipulative Bastard, or a tsundere who often forgets to explain the details to Tobio?
• Aluminum Christmas Trees:
  • The "frozen popcorn" that the girls gush about in the early chapters is real. It's frozen with liquid nitrogen.
  • Ao and Aka being twins born at the same time yet having different fathers seems impossible. However, this phenomenon, known as "Heteropaternal Superfecundation", is a documented occurrence, although an extremely rare one.
• Awesome Art: The main art style of the game itself is impressive to look at, but the opening takes it to the next level by going for a punk rock art motif that is as colorful as it is stunning.
• Awesome Ego: Eliza. Does she talk a big game and has a narcissistic opinion of herself? Yes. Can she be insufferable and ridiculous? Yes. Can she back up her talk with performance and actually prove all the things she's boasting of? Also yes. At the very least, many of them - with the parts she cannot quite match boasts of serving as excellent Comic Relief to offset her personality, actually coming across as quite endearing while at it. It further helps that, even with her obvious pride and overconfidence, she's a very sweet person with her heart firmly in the right place, a lot of capacity for love, friendship and loyalty and a desire to do good and fight for others' sake as a magical girl.
• Base-Breaking Character: Hanabi is generally liked by fans for her cool personality and her Boyish Short Hair, and is firmly on the side of the heroine team. However, some dislike her due to her ambiguous/grey morality, her shady background and her socially unacceptable deeds such as skipping classes, owning a gambling parlor, engaging in illegal gambling and even threatening, intimidating, and blackmailing other gamblers who want to quit to keep them playing, and even people who have borrowed money from her. All together, she comes across as an Anti-Hero Dark Magical Girl Warrior. It doesn't help that Hanabi rapes Tobio for defying her in one of her bond episodes in the DX version.
• Best Known for the Fanservice: Magicami is best known for a few heroines with big bust sizes such as Lilly and Aka, and sultry dresses. The Hentai scenes in the NSFW version also count.
• Big-Lipped Alligator Moment:
  • The ambiguous/off-screen sex scene at the beginning of the tutorial and then followed by naked Isana dissolving into paint. This scene is absurd enough to begin with, and causes a confusion to players as to whether that scene is real or not.
  • Somewhat unexpectedly, the Sabbath subplot that was foreshadowed up until the end of Chapter 12. While it was introduced as perhaps the most important part of the crisis the game is partly predicated on and the chapter ends with the suggestion of the characters moving on to engage in it as the next big thing, Chapter 13 picks up a completely different plotline without a single mention of it. It may be possible that future continuations of the story will resolve the issue, but so far this has not come to pass.
  • Pretty much all H-scenes from the DX version, some of them being story-stopping sex scenes, while others being Gratuitous Rape and others are gratuitous hallucinations, Mushroom Samba and dreams of first both categories.
• Captain Obvious Reveal: Kamisaman's real name being Isana isn't really a huge reveal due to her clearly featuring in the prologue cutscene under that name, with her appearance clearly matching and only possibly forgotten by the player due to being Distracted by the Sexy. The bigger secret here is that Isana is Tobio's little sister, which makes things a lot weirder and more complicated.
• Common Knowledge: There're a few glaring misconceptions that are easy to make for outsiders unfamiliar with the game and operating on Small Reference Pools:
  • "This is a game labeled as an eroge and has sexy characters, so there's gotta be a lot of gratuitous sex involved." In fact, while the game isn't shy to offer helpings of Fanservice, it's relatively tame, and actual sex scenes only appear in the DX version.
  • "The DX version is stuffed full of hentai." There's only a number of scenes accessed through upgrading UR-rarity (and a number of SR-rarity) dresses, beating bond episode requirements, completing the Demon's Tower dungeon, DX-exclusive collabs, finishing certain limited-time event storylines and going through the main story - in other words, players mostly have to go out of their way to find them, and they're not as common as may be believed. All together, playing the DX version isn't any different from the SFW one, and those expecting lots of gratuitous hentai are only going to be disappointed.
  • "Since this is a Magical Girl Genre Deconstruction, the demons are all corrupted magical girls." This misconception is reinforced by the infamous Gut Punch scenes of certain girls' deaths and corruption into demons. However, the overwhelming majority of demons are born from what's essentially mitosis on the demon homeworld, fueled by consuming the existence of humans they hunt and kill. There's some half-and-half chance of a killed magical girl being raised as a demon, but it's not guaranteed either - and demons (and zombified alternate selves) do not actively seek out to corrupt more magical girls to join them. According to some analysis, there are two types of demons (further differentiated by their hairtstyles): Deceased Magical Girls who are corrupted into demons have hairstyles identical to heroines, while the ones who are born from Demon Realm aren't. It’s also implied that all Nymphs, Mao from some limited-time events, Demon Twins, Enbi (the Arc Villain from the light novel Magicami ~Evil of Tail Court~), etc. all originate from the Demon Realm.
  • "This is an eroge, so demons must rape the fallen girls to corrupt them." While it does appear that rape leads to guaranteed corruption, most of the time demons simply kill the girls outright ; there's a 50-50 sort of chance that a slain magical girl will turn into a demon instead of dying. All together, the rape scenes are only appeared in the DX version and the aforementioned scenes are replaced with logical ones in the regular version. There are only 3 such scenes in the entire game, all of them concentrated in a couple chapters, with the rest of the game free of anything like that.
  • It's widely believed by the fans that Omnis' ability is to create/move into a new universe with desired possibilities and then leave the remaining heroines from his previously failed universe alone after he screws up. This leads to another misconception in chapters 12-13 of the 2nd arc, in which Nemesis Iroha is the original Iroha from the end of Chapter 4 (where Kaori was slain and corrupted into a demon) and Nemesis Iroha wants a vengeance against Omnis for ignoring them. Actually:
    • Iroha from Chapter 4 is the same Iroha as the one from the main universe. She's revived after being merged with the copy of her that Omnis made, as Omnis has Reality Warper, Reality Maker and Merged Reality abilities combined into one.
    • According to Ultimate Magica Iroha's dress, it's heavily implied she has to fight enough demons and learn any skills to awaken her dress step by step, from 2019 Magica, 2020 Magica to Ultimate Magica at the highest end. It's therefore impossible for Iroha to immediately awaken her dress from SR 2019 Magica dress to Ultimate Magica. It helps that when Nemesis Iroha's Executor is teleported into another universe by Vivian, the remaining heroines lose their powers and are unable to transform or awaken their dresses. If this misconception is unfixed, most fans will ignore the main story because of how dark and edgy the story is, as they believe that our Iroha isn't the original, while the original main universe Iroha becomes a Rogue Protagonist.
  • "The regular version is the DX version without the pornographic scenes. So the DX version is the original." While the regular version does have the pornographic content removed, both versions were released simultaneously. They're both equally 'the original version'. What really helps is the fact that the crossover events with The Quintessential Quintuplets and Is It Wrong to Try to Pick Up Girls in a Dungeon? are only playable/available in the regular version^note You can't play the collab event and obtain collab dresses in the DX version, but you still have the collab dresses when you change from regular version to DX version, but they'll be automatically changed into unique school uniforms, while the DX version has its own collaboration with Elf's infamous Hentai Visual Novel Kisaku.
• Complacent Gaming Syndrome: In the Player Versus Player mode, some dresses vastly outperform others, and a few select ones are almost a requirement if you're attempting to square off against other players' parties:
  • Of particular note is the Arachne Style Iroha: this dress's ability to hit for massive damage and apply Freeze to the entire enemy party with a high success rate is a veritable Game-Breaker and a lynchpin of the MGCM Metagame, and on top of that, it's quite easy to quickly upgrade its skills thanks to a limited number of tiers and a very powerful passive taking up one slot. Going up to the Silver rank and further, it's rare to see a party that doesn't include Arachne Style Iroha.
  • Not omnipresent but still very common are Evo Magica Ao (able to dish out massive damage as well as Freeze a single target and Cut the entire enemy team for damage over time) and Evo Magica Seira (offers a powerful offensive buff/enemy debuff skill and deals a lot of damage by herself).
  • Less overpowered, but still common, are the basic Akisa dress with its powerful offense/defense buff.
  • There's Kawaii Warrior Eliza with its ability to speed up the party, often used in cojunction with Arachne Style Iroha, Evo Magica Ao and other heavy hitters to make their devastating attacks happen more than once per the opponent's turn or counteract the opponent's move gauge lowering attacks.
  • In the Japanese version, most players use these dresses in the defense or offense parties:
    • From non-limited gacha: Phoenix Aka, Hallowitch Cocoa and Kaori, Ancient Wisdom Hanabi in their defense parties. For the Leucosia demon dress series, most people often use Leucosia Seira due to her attack and critical attack boost and her passive skill to reduce the damage received in the player party.
    • From limited gacha: For those who have the Magica 2020 Evo dresses, they often set Ao, Aka, Akisa, and Lilly as their defense parties. They also use one or more Magifest characters like Ultimate Magica Iroha and Lunatic Succubus Aka, etc.
• Demonic Spiders:
  • As luck has it, there are actual, literal demonic spiders in the game in the form of gigantic abominations formed of oversized female lower bodies and a single normal-sized torso on top, called Arachne. For beginner players, some elemental versions can entirely qualify as this - in particular the water-based one, which is able to bring strong abilities to bear and become an annoying wall in front of story progression. However, they effectively serve as low-to-mid-tier bosses for certain stages, and are only fought at the end of a battle, distancing them from being a "normal" enemy somewhat despite their frequent appearance.
  • A more direct example are the "miniboss"-style Magi-Raven, Magi-Taurus and Magi-Lizard, which can crop up among regular demon waves in the mid-game and greatly worsen your day if you aren't overleveled, as well as the more highly evolved late-game demon variants. Water Magi-Taurus, in particular, can ruin a successful battle due to its Freeze-inducing Herd-Hitting Attack, which it can cast with unpleasant frequency; things get even worse when there's multiple of them in a wave.
  • There's Saber: though considered a "foot soldier" kind of demon, it's able to inflict devastating damage and restrictive status effects with one hit, and can prove the bane of any player without sufficiently leveled and beefed-up dresses for their girls.
  • Watch out for Crusader demons. Their third skill allows them to single-attack an opponent with massive damage. However, this skill also inflicts stun to Crusader itself.
  • In the main story, Demon Realm's macro-organisms can be dangerous. Everlasting Abalones can inflict guaranteed stun damage on a magical girl, while Kaiawasedake critters can cast poison towards the party. Unlike the other status ailments, poison won't get removed by turns (can only be removed using a certain magical girl's skill) and its damage increases every turn. When defeated, Kaiawasedake has a passive skill that causes one random character to receive massive damage from it.
• Ensemble Dark Horse: Akisa has gained a sizable following among the playerbase due to her adorably small stature and features and endearingly serious Teen Genius personality, as evidenced by her placing first on the character popularity poll in the Summer 2020 live-stream. This hasn't gone unnoticed by the developers, who went on to release a drama CD, dakimakuras and an Image Song for her.
• Fandom-Enraging Misconception:
  • Some fans are prone to FlameWars when someone voices a belief in the DX version holding primacy over the SFW one due to the additional lewd material the SFW one lacks.
  • Assuming that, just because this is an eroge, demons reproduce by raping the magical girls. In truth, while this fate does seem to guarantee corruption, even in the DX version, demons prefer to simply kill the girls, and about half of those they kill rise as demons as they die. Predominantly, however, demons reproduce by apparent asexual mitosis after they successfully manage to devour a human.
• Fan Nickname:
  • In order to differentiate the original demons from demons who are actually dead and corrupted heroines from alternate universes, it’s best to call the former “demons” and the latter “Demonized Selves.” The zombified heroines from alternate universes are called “Zombified Selves”.
  • If they say "this UR dress has a scene", they actually mean an H-scene from the DX Version.
  • The monthly event "Eliza and The Orb-Spouting Abalone" is sometimes called a "Clam-fisting" event.
• Fanon:
  • There's a fan theory that the dresses that players draw from the gacha are, quite literally, the possibilities of other versions of the same relationship: the condensed power of a magical girl, pulled into a different reality. That's why dresses have a limit, but players can expand their possibilities, because they're further condensing the power of other realities into your own.
  • Omnis has the ability to transfer the heroines' subconscious into their new bodies. The heroines always get resurrected, but cannot remember their deaths because their dead bodies and their subconscious get merged. Their subconscious gets transferred into their new bodies and their memories are overwritten by their new copies that Omnis created. While the ones who are corrupted into demons can't be merged with the copies, it is possible to have their subconscious invisibly transferred and have their memories overwritten by their new copies (Remember: Believe in infinite possibilities). The reason why White Omnis' corrupted magical girls still have their subconscious and memories? It's because White Omnis refuses to transfer their minds by simply communicates to his recently corrupted magical girls. Why? He's lost his mind, although he has a good goal. Vivian's whammy words to Akisa imply that their "physical bodies", not the individuals/identity, may be partially fake. This headcanon has a function to ease the Fridge Horror implication which questions whether the subconscious of the heroines who are slain and their corpses transforming into demons are transferred into their new bodies.
• Fanon Discontinuity: Some fans prefer to disregard the plot point about the Sabbath battles working like a Battle Royale elimination event due to how much wasted magical girl life it implies, and instead believe in the dimensions working together and finding a less brutally wasteful way to solve the crisis. It's helped by the fact that the Sabbath subplot is only there to justify the Player Versus Player mode in-universe and is very superficial in the story itself.
• Genius Bonus: There's a strange arrowhead creature picture in a few "R" rarity dresses and his monochrome artwork of Cocoa. According to GSK's Word of God, it's actually a cartoonish planarian, a flatworm which can be cut into pieces, and each piece can regenerate into a complete organism.
• Goddamned Bats:
  • Some of the foot-soldier type demons are much more annoying and dangerous than others. The Falcons, in particular, are going to be a bane of any dress of an element they're strong against with their triple attack that debuffs the vicitm's offense stat and turn-hastening ability speeding up other demons (including other Falcons). Witches are also this due to being pushovers, but able to buff the demon squad with +70% defense, slowing you down greatly and endangering the weaker parties.
  • Some subtypes of Nymphs, enemies common to timed events, work like this. All Nymphs are fairly fragile, but able to speed the entire demonic force up, dispense potent buffs and have annoying status effects on their basic attack, as well as gain extra turns if they manage to land a special attack on a buffed magical girl. Water Nymphs are able to grant barriers absorbing damage; Lightning Nymphs grant extra turn speed to their entire squad every time one of them is struck, which turns multi-hit multi-target attacks, normally the strongest abilities in Magicami, into massive liabilities.
• Goddamned Boss: Mermaid and Black Mermaid demons aren't deadly to a party, but their huge number of hit points and hit point regeneration passive skill are enough to annoy players expecting to defeat them easily, unless you have heroines that have skills that inflict "Recovery Seal" and "Stigma" Status Effects.
• Good Bad Bugs:
  • Hanabi's distorted neck bug becomes one of several hilarious bugs, and many players claim that the bug is caused by Hanabi cracking her neck side to side in her home screen animation.
  • Another hilarious bug is when the heroines in the gameplay become invisible, but not their weapons. Many players joke that the heroines must be using camouflage ninjutsu.
• He's Just Hiding: The straight-haired Alternate Self of Lilly in Chapter 13-15 is obviously dead after being killed by the Drake demon, but many fans hope that she's revived by her Executor from that world, as the Executor can use his Reality Warping ability. There are a number of dress episodes starring the straight-haired Lilly. But we don't know whether that version of Lilly is the same one from Chapter 13-15 after being revived by her Executor, or she's from the Alternate Universe and not from Chapter 13-15.
• Hilarious in Hindsight: Both Magicami and Magia Record: Puella Magi Madoka Magica Side Story, games about teams of magical girls in deconstructive and dark universes, happen to have a spirited pink-themed girl by the name of Iroha as their first protagonist. With Magia Record shutting down on September 29th 2020 and the English version of Magicami releasing on September 1st 2020, some have joked about the character being inherited or migrating into a new body, since, though their personalities are not identical at all, they do share some important underlying traits and motivations.
• It Was His Sled: Because many players know this game is rated 17+ or have watched Puella Magi Madoka Magica and/or Magical Girl Raising Project, they already expected the dark twist of the main story: the fact that some demons are slain and corrupted heroines and the Deadly Game between magical girls.
• Les Yay:
  • In the Shinsengumi event, Ao's sporty Shinsengumi dress and her tomboyish nature makes Kaori imagine dating a handsome person with Ao's fit and slightly muscular appearance. Then, she approaches Ao grinning excitedly.
  • From the same event above, Akisa from the alternate universe blushes after Ao rescues her from tripping.
  • Side dress episodes mention that Aka and Ao, despite being twins, are so different in appearance, clothing style and bearing that strangers, at a passing glance, mistake Aka for a mature wife and Ao for her husband (at least until they see her from the right angle). The two don't mind it as much as they could have. Furthermore, Aka is even fine with Marianne drawing a clearly NSFW doujin depicting her and her sister together and reads through it herself after the latter flees in shame.
  • In "My Name" Halloween event, both Iko and Marianne have their body switched after eating a certain plant from Demon World, and one of their attempts to reverse the effect is to kiss together on their lips, Makes Sense In Context.
• Memetic Mutation:
  • Baby Shark Eliza.^ExplanationEliza's bikini dress has "Baby Shark" printed all over much like brand titles are IRL. Quite possibly a Shout-Out to Pinkfong's Baby Shark song.
  • This official sticker pack itself has the faces of heroines, the demons and including Omnis done in a memetic StylisticSuck-y artstyle.
  • KISS Mahou Shoujo. ^ExplanationThe Beast Forms of 12 magical girl heroines have bodies and hair color which are completely black and white (except their eyes), complete with face tattoos, causing many fans to compare them to KISS band members.
• Misaimed Merchandising: Since this is a Magical Girl game aimed at adults, Studio MGCM themselves also promote some giveaway and collaboration merchandise that is mostly aimed outside that demographic:
  • The daimakura pillow of Tobio's bald middle aged Alternate Self (which can be flipped over to the handsome main universe version on the other side), that could only be obtained by posting the hidden bald Tobio during ad campaigns in November 2020. Something that women want to have.
  • A collaboration with Dyson (a brand of vacuum cleaners): one lucky winner will be given a vacuum cleaner which is Seira's (one of the magical heroines) magical weapon.
  • A collaboration with Onkyo earphones: a pair of special earphones with the words and UI voices of Kaori Tomonaga (one of the magical heroines).
• Never Live It Down:
  • One thing the audience tends to remember about the player protagonist Tobio is the main story scene where he doesn't completely notice Kamisaman's crucial introduction of Omnis and Akisa's awareness of the overwhelming numbers of demons, which leads to the infamous Gut Punch where the recurring deaths and occasional corruptions of the heroines occur.^note Technically, Tobio permanently lost two (or three in NSFW version) heroines in the party, as the ones who are corrupted into demons cannot be merged with his ability. Instead, they’re replaced by copies he created, although the copies have completely identical personal traits and pasts like the previous ones. Many fans also blame Kamisaman for not telling Tobio the whole truth, but it’s probably done just to spice up and prolong the story.
  • Hanabi is infamous among the playerbase for her viciously exploitative and manipulative treatment of Tobio in her early bond episodes, with the NSFW version making it particularly damning due to Hanabi outright raping him for defying her. Though she undergoes Character Development and her "prime" version seen in the main game proper does not ever reach these lows, this gives her a more negative rep among the fans, since the bond episodes are still implied to be canon.
  • One thing that the audience tends to remember about the heroines is the infamous New Year 2020 event story, where the heroines just end up killing Kannagi, Mao's giant demon pet when they're attempting to befriend Mao. Dismayed, many players complain that the heroines are baddies.
  • Besides Aka's slightly unhealthy libido, one other thing that the fans tend to remember about her is that she molests Sea Drake offscreen (in the DX version, it's an outright rape) at the end of the "Yo Ho! A Pirate's Life!" limited time event in order to defeat her and to protect Aka's friends from her. Even Sea Drake is disgusted and begs her for mercy after that.
  Sea Drake: STOP... PLEASE STOP... I PROMISE... I WILL LEAVE YOU ALONE...
  Aka: I can't do that. I mean, that look on your face is telling me you want more.
  Sea Drake: WHAT ARE YOU SAYING? Y-...YOU, YOU ARE THE DEMON!!!
• Periphery Demographic:
  • Men are this game's target group. There's a fair amount of fanservice, and an NSFW version to boot. But it also appeals to some female players, thanks to the vivid atmosphere and cute heroines.
  • A few players are drawn to this game in part due to an interest in quantum physics, as The Multiverse is a core plot point of the game and quantum mechanics are directly Discussed in the game by its smartest characters.
• Rated M for Money: The colorful visuals and deep plot are strong selling points, but the plentiful fanservice and the NSFW version certainly help attract audiences. The evidence? the DX Version yields profit 10 times the profit of the regular version.
• Rescued from the Scrappy Heap: Eliza's selfish tendencies and jealousy towards Akisa haven't won her much favour with the fans (who, as noted above, tend to adore Akisa). In Akisa's birthday skit in 2019, Eliza gives her a present and appreciates her positively as a Friendly Rival.
• Scrappy Mechanic: You can't fight against the same opponent in Sabbath Battle after you lost 5 times to them, which is detriment to users who want to fight with Trial-and-Error Gameplay.
• Song Association: Because this game using GANG PARADE's songs as background music for its combat component, some players have come to associate GANG PARADE's songs with it.
• Spiritual Adaptation: Before MGCM was released, Magical Girl Raising Project came out, and both happen to have some key features in common. The magical girls are scouted through a smartphone app, they fight demonic entities, they have hitatsus and kiais, there's magical girls battling each other, they get into lethal trouble, there's a blob-shaped mascot, and the girls have weirdly shaped weapons. Coincidence? Though there are also important differences: the magical girls from MGCM are heavily implied to be non-lethal K.O.-ed when defeated in battle between magical girls (excepting those in the alternate world from Chapter 13 onwards; fortunately, it’s not a Sabbath Battle). On the other hand, in Magical Girl Raising Project, the losers just die. MGCM is Lighter and Softer and more fanservicey than Magical Girl Raising Project, the former even averting the setting where "If the main heroines die in the game and even in cutscenes, they'll never appear in next chapters", thanks to The Multiverse and Omnis' dimension-creation and Merged Reality abilities.
• That One Boss:
  • Necessarily overlaps with That One Level. Progress through the main story can hit unexpected roadblocks in the form of the floating boss types: Leucosia (fire), Parthenope (water) and Ligeia (lightning). While the first one is simply more difficult than the regular Arachne bosses the player'd seen before this point, Parthenope serves as a DPS and survivability check by being able to heal and un-debuff itself and its allies, and Ligeia is able to stop an unprepared player dead in their tracks thanks to its high DPS output and a permanently-on passive counterattack ability. The player will need to level up their strongest dresses, get powerup orbs to slot into them and obtain new dresses from side events or gachas in order to overcome them: by the time they run into these bosses, a beginner is not going to have a party powerful enough to break through this kind of opposition.
  • Unsurprisingly, the same applies to the same boss types encountered in the Demon's Tower. There, they're even more dangerous thanks to having extra levels and backup from powerful dresses fielded as zombies on their side.
  • The Beast Form of Iroha's Nemesis alternate self in the final battle of the 2nd arc's final chapter is almost impossible to defeat without using revives, besides having huge HPs and skills that are identical to Iroha's Ultimate Magica dress, one of the most powerful dresses. She also has two Anti-Debuff passive skills: one that automatically removes her own debuffs (maximum of 2) and activates her attack up buff every turn, and the other is immunity to some status ailments: stun, freeze, sleep, forget, and bleed.
• That One Level:
  • Due to how elemental affinity of the demons you find changes as you progress, your starter dresses will eventually run into unfavourable combinations they'll be notably weaker against. The levels that begin to introduce water-based demons are a particular early-mid game example.
  • While advancing up the Demon's Tower, you're almost guaranteed to hit several battles that offer much more dangerous and hard-to-beat combinations of dresses and demons. The exact battle makeup and order changes every month, but you can count on finding at least some particularly devious and simply unfair squads you must beat to progress, particularly in hard mode.
• They Wasted a Perfectly Good Character: Many fans wish that Lilly could meet and communicate more with her straight-haired alternate self. So far, she's only reappeared in 2 alternate reality episodes: Magica 2020 Evo Lilly's dress story and the side story in Magicami Visual Fun Book. We only see Tobio and his avatar Omnis by his lonesome (sans his heroines) getting teleported to her native Dark World and its own White Room, meeting her in Chapter 13 and witnessing the alternate Lilly ultimately dying, in Chapter 16, although the "prime" version of the heroines are able to arrive in that universe and meet Lilly's alternate self in the same chapter. However, it’s further implied that the version of Lilly shown in the alternate episodes is either from a different possibility/Alternate Universe than the one shown in Chapter 13 or she's resurrected/cosmic retconned by the Executor of that world, and may still be alive out there.
• Too Bleak, Stopped Caring:
  • The game's main story is a lot darker and more grim than some may expect from what, on the surface, appears to be a playfully sexy, fanservice-laden game that offers little indication of just how hardcore it will get story-wise. The Gut Punch at Chapter 4 Episode 5 catches players unawares, and those who came for simple titillation may be driven off by the unexpected and unpleasant darkness that ensues. And the amount of darkness almost rivals Puella Magi Madoka Magica and Ryukishi07's works; this is particularly pronounced in the DX version, which adds extra layers of Gorn and Fan Disservice to these elements of the story, and is also the one players mostly looking to ogle pretty girls are most likely to play. Good luck finding any fandom that isn't into H-Scenes. Fortunately the later arcs are less darker than the first one.
  • While some of the NSFW scenes in the DX version are entirely tasteful, unless you're into rape and bizarre hentai works, others among them instead feature surprisingly nasty and unpleasant scenarios with Alternate Reality Episode glimpses and gratuitous hallucinations of your beloved heroines getting gangraped and abused (or the inversion, the demons themselves are raped by humans, including Aka) as your "reward" for unlocking the episode. This can easily turn expectation of incoming sex scenes into something of a minefield - you're never quite sure whether you'll see one of your girls get some deserved love or suffer a horrible, heartbreaking fate.^note just a few examples are tentacle rape, literal Mind Rape, gore, bestiality, pedophilia, Bizarre Human Biology, Body Horror, transformation, Interplay of Sex and Violence, and petrification; one of Nijisanji's Virtual YouTubers discovered it the hard way, and another one explains in Japanese here.
  • The infamous New Year 2020 event polarizes among the fanbase as the heroines hold an Idiot Ball and ended up killing Kannagi, Mao's demon, who doesn't attack people. This causes Mao to take Face–Heel Turn against humans and the heroines, even Lilly herself is aware what have her friends done and calls them for it. What doesn't really help is the fact that Mao becomes a recurring villain in some events. After being defeated by the heroines, she gets Killed Off for Real by Demon Twins in the Christmas 2020 event. Because of this, the morality of the heroines are questioned and players consider them as designated heroines.
• What Do You Mean, It's Not for Little Girls?: This game shares two major traits with the mammoth Shoujo anime franchise Pretty Cure: cute evil-exterminating magical girl warriors and bright, colorful visuals. However, the former is rated 17+ due to Fanservice-laden characters, stripperiffic costumes, Jiggle Physics, and panty shots in the gameplay. Not to mention mind-screwingly Darker and Edgier moments, Humanoid Abomination demon bosses and Cosmic Horror aspects that edge this game into Magical Girl Genre Deconstruction territory (and there’s an official NSFW version for PC, and it makes things even worse). Fortunately, it's hard to mistake I=MGCM for an actual children's product, or something "safe" for kids.
• Woolseyism: The English version of the game is chock-full of this. A few examples include: turning Iko's Hiroshima accent (which English-speakers generally have no familiarity with anyway) into a Southern US one, adding some fourth wall breaks (and some Leaning on the Fourth Wall dialogues), altering some shout-outs to be more comprehensible to non-Japanese etc.
