Butt Monkey: Not as severe as some examples, but Ayumu usually gets the short end of the stick at any given moment.
Taken Up to Eleven at the end of Episode 1 of Of The Dead — he was forced to fight a Squid Megalo in broad daylight to save Taeko, where most of his schoolmates can see... they quickly take shots of him and his exploits even made headlines across the internet. And as if that wasn't bad enough, the Mystletainn broke up after the fight, rendering him naked and unable to wipe out his schoolmates' memories!
Ayumu dehydrates when exposed to direct sunlight. So obviously he gets the window seat in class.
Another, far more subtle cue in the novels, when during gym class he is able to narrate a lot of details about his female classmates, but is completely ignorant of most of his male classmates including the school basketball star. Shows where Ayumu's priorities lie.
Crouching Moron, Hidden Badass: Not exactly a moron per se, but Ayumu is mostly a servant to his ladies. But beware: given the chance, he can rip a Whale Megalo's head off, tear Kyoko to shreds with the Mystletainn, or punch the King of the Night out of immortality.
Cursed with Awesome: Being a zombie grants him functional immortality, regeneration and Super Strength. Becoming a Magical Garment Girl gives him even more powers. However, he lacks a number of Required Secondary Powers, meaning his body will tear itself apart if he uses his super strength too much, and his Magical Garment Girl outfit is intensely humiliating (but thank God for that memory-wash ability taken from Haruna).
Dragged into Drag: Both as a Magical Garment Girl and as a Kisugi sister parody. The former mode puts him in a pink frilly dress, and the latter mode (seen in the first OVA) puts him in a unitard. Apart from those examples, episode 6 of season 2 has him crossdressing to advertise the tsundere cosplay cafe per popular demand.
Heroic Sacrifice: He always gets better (even from otherwise fatal injuries), but this is still played straight at the end of Episode 10, when he takes the time bomb the King of the Night placed on Haruna's head, allowing it to explode in midair, literally tearing himself apart. His Heroic BSOD at that moment also made his "death" a little bit longer. Haruna, Seraphim and Maelstrom reassemble him at the start of Episode 11, but it took Haruna's mind-dive to finally convince him to come back to life.
Masculine Girl, Feminine Boy: Feminine Boy to Maelstrom's Masculine Girl. During their summary marriage ceremony (which was purely accidental, never mind that Maelstrom continues to insist that it's legal), he was the one who had to wear the wedding dress.
Our Zombies Are Different: Despite being a zombie, he looks, acts and thinks like normal people and sunlight dries him out. He lampshades this trope in the second volume of the Light Novel when he tells Tomonori that he's not sure if "zombie" is the right word for what he is, but it's what he thinks of himself as.
Would Hit a Girl: Scratch that — he would chainsaw a girl if they messed with his friends.
Yank the Dog's Chain: Zigzagged, via a Chekhov's Gag through the first episodes of the first two seasons, where Ayumu was exposed as a Magical Garment Girl to his classmates after fighting a Megalo on the school grounds. Except he wasn't lucky the second time around: with Mystletainn broken and he unable to erase their memories, he ends up at the center of an In-UniverseMemetic Mutation, much to his despair. And even when he thought he'd finally get over that incident once Mystletainn was fixed, his classmates later had him Dragged into Drag again afterwards anyway, this time to advertise the tsundere cosplay cafe.
A necromancer and possibly the most powerful Magical Garment Girl ever, able to both kill and revive a person with her voice alone. As a result, she only speaks through writing words on a notepad, and constantly wears plate armor just to prevent her powers from going out of control.
In Of The Dead's Delusion Eu segments, the real Eu actually talks to her Delusion counterparts.
Emotionless Girl: Ayumu initially assumes she's this, but Seraphim correctly guesses she's simply hiding her emotions.
After the events of Episodes 11 and 12, this is starting to slip a little. In the first OVA she occasionally cracks jokes, albeit still in writing, and actually writes out "wwww", the Japanese equivalent of the emoticon "LOL".
Idol Singer: Steals the entire competition from Haruna, Seraphim and Sarasvati with her words' powers temporarily transferred to Ayumu via Ariel's machine. Then she's joined by Haruna due to said machine temporarily breaking down.
Power Incontinence: Potentially one of the worst cases on record. Unchecked, her magic would spill out through her words and feelings. Even when she dies, her magic will rage on.
Power Limiter: She prevents her magic running wild by wearing her armor, not speaking, and controlling her emotions. Unfortunately, in episode 9 she lets her emotions get the better of her under duress, leading to some pretty nasty things happening such as her friends getting squashed by a giant kappa doll and Maelstrom nearly dying. And all because the King of the Night threatened her friends.
She speaks in episode 11 and in episode 12 she sings, though only because her powers are temporarily transferred to Ayumu so she can do so. Also with the help of Haruna. She does again in Of The Dead episode 7 thanks to Haruna borrowing her mana.
She's also able to speak while projecting her spirit (as she does in Of The Dead episode 10).
Weirdness Magnet: Sarasvati obviously sees her as this, otherwise she wouldn't put a hit on her in the first place.
A self-described genius "Magical Garment Girl" from Villiers who fights Megalo, though her genius seems based in a whole different universe. Her weapon of choice is a pink chainsaw named Mystletainn, but she accidentally transferred most of her powers to Ayumu while trying to erase his memory. Now only he can wield Mystletainn against the Megalo while she regenerates her powers. In the meantime, she's squatting at his house and cooking fried egg in all its forms.
Clingy Jealous Girl: She gets jealous of Ayumu's marriage to Maelstrom, and asks him to kiss her in Episode 8. When he questions her as to why she wants a kiss, she responds by beating him up a little bit. Ramped Up to Eleven in Episode 9 of the second season after seeing him get too friendly with the buxom Nene.
Empathic Weapon: Her Mystletainn, whose allegiance shifted to Ayumu after absorbing most of her powers. However, in Episode 11 it reaffirms Haruna's ownership of it, allowing her to transform full-time again and help Ayumu double-team the King of the Night.
Lens Flare Censor: Flat-out abused by her, with her penchant for attempting to transform into a Magical Garment Girl — a process which destroys her civilian clothes, leaving her naked once the magic wears off (which, thanks to losing most of her powers to Ayumu, now only lasts a few seconds).
Gets hilariously subverted in Episode 8. Her boiled hijiki (seaweed) is a burnt black mess, but still manages to taste just as good as the eggs.
In the novels she's much more a Supreme Chef with a tendency to produce whole meals of just one thing, or make something that looks... not unpleasant, but kind of weird. (The focus on eggs is something of a Flanderization.) It's always amazing, but there's no variety. As a result, Ayumu's classmates regularly pillage his bento and trade back from their own, which he's happy about and bemoans at the same time because there's often none of Haruna's cooking left.
A beautiful, skilled vampire ninja obsessed with her sword technique. She came to ask for Eu's help in a secret war her clan is fighting, but after losing a fight against Ayumu decided to stick around his house instead. She can make sharp objects out of leaves.
Actor Allusion: Hercat-ears experience. Amusingly enough, earlier in that same episode, Maelstrom pulls off the "Moe Moe~ KYUN!" stance while her classmates are trying to help her get Ayumu to reciprocate her love for him.
The Ninja Maid scene that serves as the season's climax, though, does play this straight, minus the "Moe Moe~~ KYUN!" bit.
"You're a crossdressing piece of shit festering in a bag of rotten garbage, but I believe in your strength."
Atomic F-Bomb: When she figures out Ayumu is the reason she and the rest of the girls at the indoor water park ended up wearing extremely stripperiffic swimsuits, she yells "You piece of SHIT!!!!!!" as she smashes his face in with her foot.
Idol Singer: Not by choice, but only to match up to Sarasvati.
Laser-Guided Karma: A positive example — because she relented on her order to kill Eu, the latter resurrected her with some of her own blood after the King of the Night kills her.
Lesbian Vampire: Comes across as this in Episode 5 by way of giving Haruna a mouth-to-mouth anesthetic before sucking some blood out of her. Come Episode 7, it is revealed that a heterosexual kiss is tantamount to a Shotgun Wedding in her culture.
Lethal Chef: She helps Haruna cook at the start of Episode 4, which results in something that only Ayumu can barely stomach. She gets slightly better.
Our Vampires Are Different: Able to grow bat-wings that let her fly and conjure weapons from leaves. Occasionally needs to drink blood, using her kiss as an anesthetic. Apart from that, indistinguishable from a normal human (and can even walk under direct sunlight).
To Be Lawful or Good: She was given orders to assassinate Eu in order to prevent more Megalo from appearing. Ayumu calls her out on it, forcing her to admit that she just doesn't have the heart to do it anymore.
Town Girls: The Neither to Sarasvati's Femme and Maelstrom's Butch. She uses tough language toward Ayumu and wears slacks (usually dark blue jeans, which she's often, if not always, wearing in promotional material) more often than Sarasvati (if Sarasvati even wears any pants at all).
Tsundere: Particularly in later novels/Of The Dead, when her feelings for Ayumu start to emerge.
Another vampire ninja (from a faction which rivals Seraphim's) who fights Megalo with bowls of pork ramen. After accidentally kissing Ayumu, she finds herself married to him (becoming the fourth girl in Ayumu's harem) thanks to the traditions of her family, but seems okay with it. She also studies at Ayumu's school under the alias "Yuki Yoshida".
Accidental Misnaming: She doesn't take too kindly to her new, tomboyish-sounding nickname from Orito (an alternate reading of her civilian alias), but is fine with Ayumu using it (except for one moment of shock from nearly dying in episode 9), since she found his alternative — "Yuki-chan" — even more embarrassing.
Early-Bird Cameo: In Episode 1, she was among the students taking pictures of Ayumu in drag; in Episode 2, while warming up for PE; and in Episode 5, leaving a ramen shop as Kyoko, who apparently slit her throat the previous episode, walks by.
Hidden Buxom: Played with. Her clothes seem rather indecisive if they want to hide her E cups or not at any given time. Ayumu notes in the novels that she dresses to hide her actual bust size in school and when operating in the field, but didn't bother when out on a date.
Masculine Girl, Feminine Boy: Masculine Girl to Ayumu's Feminine Boy. During their summary marriage ceremony (which was purely accidental, never mind that she claims it to be legit), he was the one who had to wear the wedding dress.
Meaningful Rename: Subverted. Vampire ninjas are given a new name when they finish their training and are transformed into a vampire, but it turns out "Maelstrom" came from a monster's attack in a video game that her faction's leader was playing at the time and thought sounded cool. She came up with the "Yuki Yoshida" name for public use simply because she thought it sounded suitably girly.
Mon: Apparently has the Magical Garment Girls' ultimate weapon bonded to her. When she gets squashed by a giant kappa doll in episode 9, it triggers the invocation ritual, and it takes a Cooldown Hug to prevent things from getting apocalyptic.
Musical Assassin: Assists Sera and Sarasvati in closing the gates of the underworld with a triangle.
Town Girls: The Butch to Seraphim's Neither and Sarasvati's Femme. Although both she and Seraphim are seen wearing pants (in Sera's case, this also includes jumpsuits, as seen in the first OVA) in nearly every, if not every, episode, Maelstrom is definitely a Shorttank that is often mistaken for a boy depending on what she's wearing at the moment.
Reasonable Authority Figure: She orders Seraphim to assassinate Eu to prevent her powers from attracting more Megalo, then puts a hit on Sera herself for disobeying her orders, but is nevertheless willing to save her and Haruna from the King of the Night and even helps the former (together with Maelstrom, herself from a rival clan) seal away the gates to the netherworld.
An acquaintance of Orito. The only victim of the serial killer to escape, she spends time in hospital to recover from her injuries. In reality, she is the serial killer herself. Kyoko is a Magical Garment Girl in disguise who used to be a classmate of Haruna at Matelis.
Averted in Episode 8 of Season 2, where she outright states that even she's confused by these feelings for him, after stabbing him yet again with her sword. She then tells him her punishment is to be forgotten by everyone, but he promises her he won't, no matter how much time passes.
Yandere: Subverted in Season 1 (she was only pretending to like him). Played straight in Season 2, when she genuinely falls for him, and tells him such, right after she stabs him yet again with her sword, which somehow turns into a hug.
Your Soul Is Mine: Attempts to gain immortality by killing people and offering their souls up for power. This also gives her a stack of extra lives as well as Megalo and Vampire powers.
Voiced by: Shinya Takahashi (Drama CD), Hiroyuki Yoshino (Anime) [Japanese], and Anthony Bowling [English]
Ayumu's only normal friend at school. Obsessed with girls, but lacks the approach to actually get a girlfriend.
Ambiguously Bi: See the ending and his reactions after Ayumu gains popularity.
Locked Out of the Loop: Ultimately subverted concerning Ayumu's Unwanted Harem during Episode 3. Continued to be played straight concerning Ayumu's new lease of (undead) life, the supernatural nature of his Pretty Freeloaders, and Kyoko's true nature — although that one's probably for the better. Interestingly, in the first episode it's stated that Ayumu's more worried about the Unwanted Harem than the others.
Voiced by: Rie Yamaguchi [Japanese] and Erica Harte [English]
Ayumu, and Maelstrom/Yuki's classmate, who holds unspoken affection for the former.
"Do It Yourself" Theme Tune: Her voice actress, Rie Yamaguchi, sang both ending themes, Kizuite Zombie-sama, Watashi wa Kurasumeito Desu ("Know that I'm Your Classmate, Mr. Zombie") and Koi no Begina Nan Desu (T_T) ("I'm a Love Beginner (T_T)").
Fallen Hero: As shown in a flashback in Episode 9 of Season 2, pre-zombification he was among Eucliwood's seven most loyal paladins (and a Knight in Shining Armor to boot), who fell into disgrace after killing one of them.
It's All My Fault: Implies this in his final Breaking Speech to Ayumu when telling him not to blame Eu when the day comes when he understands the hardships of immortality—and this is before the incident that led him to believe immortality sucks (where he killed another of Eu's paladins) is even hinted at.
A pink-haired girl who often shows up drunken in the school infirmary. In reality, she was a Magical Garment Girl currently under the Queen's Curse following a failed coup she led (and Ariel concocted) against Queen Lilian Lilith a century before Ayumu's death and subsequent zombification, occasionally turning her into "Takeshi Kurusu", a middle-aged man who happens to be a teacher at Ayumu's class.
Affably Evil: Although she was a leader in a failed coup, in season 2 of the anime at least, she isn't depicted as particularly evil. At least compared to the King of the Night, who brainwashed Kyouko who then killed people and stole their souls. She even considered Ayumu to be a potential drinking buddy due to their interactions in earlier episodes, at least until he finds out how crazy she is. She also teleports the students she launched into the air safely back on the ground before leaving as well. And near the end of season 2, Chris even hangs out with Naegleria, and both of them seem fairly friendly towards each other despite their past as bitter enemies.
Arson, Murder, and Jaywalking: After revealing herself as Ayumu's enemy. He asks her, if she was the expert on magic, that Haruna mentioned, the one behind yesterday's Megalo attack, which he somehow ends up asking if she was the reason summer is hot.
Big Bad: From the fourth volume onwards and Of the Dead.
The Dreaded: In-universe, she's referred to as a powerful Magical Girl, if not the most powerful, by many characters, including Seraphim and Ariel. The latter even mentions that she would lose in a fight against her former teacher if it really boiled down to it. Although in the past she tried to overthrow the queen, the most she ever does in season 2 of the anime is launch some students into the air, and then launches Ayumu back a bit with some wine tossed in his general direction after he tries to attack her. She never actually harms any of them either, and teleports them back to the ground shortly as she teleports away.
Early-Bird Cameo: In episode 1, when he's chatting with some girls and later is snapping shots of an embarrassed Ayumu along with Maelstrom and dozens of other students.
The Gadfly: Among other things, he tells Ayumu he can cure Eu's fever by dancing around in his underwear while yodeling, then blowing on her while shaking his butt in the air. He's endlessly amused when Ayumu falls for it.
A yaoi doujinshi and an old friend of Eucliwood. She is also the one who drafted the concoction Chris uses to temporarily transform her back to her old self, as well as a member of Eucliwood's seven paladins.
The Tease: After she realizes that Haruna was extremely upset because of a misconception between her and Ayumu, Naegleria plays that part up, saying that a guy should be able to do whatever he wants with a woman. This doesn't go well with any of the women living with him, and Seraphim swings her sword down on his head. Ayumu for his part, was completely innocent.
