The protagonist of Soul Eater Not!, she is a weapon from Japan who developed a strong admiration toward Maka after their first meeting, even emulating her by putting her own hair in pigtails.Prior to the beginning of the series, she never had a chance to transform before she arrived at the DWMA, where she eventually finds that her weapon form is a Halberd. There is an issue with her transformation, however. While she is capable of completely transforming her body many note how she lacks a sharp edge, making her useless overall in actual battle. And if that wasn't enough, she must also eventually decide who will become her real meister, Anya or Meme, due to the idea of a weapon with two meisters being unheard of and most likely not possible. The overall story revolves around Tsugumi trying to conquer these problems while also simply living her life as a student at the DWMA.
A-Cup Angst: She's not too proud of her small bust especially when compared to her companions namely Meme.
Hero-Worshipper: Tsugumi becomes a bit of one towards Maka after meeting her.
In Love with Love: She's always introduces herself to the audience describing herself as such. When Akane said a love confession was just a joke, she felt relieved because she wants to find a purpose in life before pursuing any romance.
Love Triangle: Meme and Anya are competing over who gets to be her meister. Due to the nature of weapon/meister pairs, this is how it comes off.
Meaningful Name: Her surname is Harudori, with "dori" written as "bird". Therefore "Haru-bird", therefore "Halberd".
Only Sane Man: While she has her good share of questionable moments, Tsugumi is arguably this as she appears more down to earth than her friends and is easily frightened when she witnesses them doing unimaginable things.
Ridiculously Average Girl: In the first chapter Anya says she could only stand out of she passed herself as the "God of the Common People" and correctly guesses she copied her hairstyle from someone else. In fact that's why Anya likes her; she thinks Tsugumi epitomizes the "common" folk she wants to get used to.
One of Tsugumi's two roommates, and a meister with unimaginable strength and fighting prowess. Ridiculously ditzy, even forgetting her own name once in a while, but is shown to become serious when either Anya or Tsugumi fall into trouble. What is notable about Meme is that she is the most capable of the three girls in hand-to-hand combat, not even needing a weapon, though she still wishes to become Tsugumi's partner.
Ambiguous Disorder: Her constant memory loss usually seems a result of a never paying attention to anything, but other times (especially her Day Inthe Limelight) it comes off as a genuine mental disability where she forgets things even if she's trying to paying attention and knows how important they are. However, it's heavily implied in the anime that the memory loss is a side effect of Shuala's mind control, which is stated to be far stronger than that of everyone else who falls victim to it. In the ending of the anime, which tales place long after she's been freed of it, she doesn't appear to be anywhere near as air-headed and forgetful.
Brainwashed and Crazy: Thanks to Shaula's mind control. For the most part, she remained in control of her actions, but Shuala effectively used it spy on the DWMA and was able to take control of her body when needed. It's also heavily implied that her terrible memory was a side effect of this, which, if this is true (and the ending of the anime seems to support this), means she's been like this for the entirety of the series.
Boobs of Steel: Despite all appearances, she's the most capable and physically strongest fighter of the three girls. And she's also the most well endowed.
Crouching Moron, Hidden Badass: When attacked while she was asleep, she was able to fight off the attacker without waking up. Even when not sleeping she's incredibly fit, being able to jump about a dozen feet to snatch a fast-moving baseball right out of the air.
Cloudcuckoolander: She once spent a whole chapter wondering around Death City, carrying a handful of random items that she didn't even remember having in the first place. There also numerous moments throughout the manga where Meme would unassumingly say a phrase completely wrong, which would prompt Anya to immediately correct her.
Forgetful Jones: She has an amazingly poor memory. It's mostly played for laughs, but a chapter going through her What Did I Do Last Night? ends with her wondering what else she's already forgotten or if she'll end up forgetting things she really doesn't want to, like her friends or even the thoughts she's having right then.
Heavy Sleeper: So much so that even when she's fighting someone or taking off her own clothes in her sleep, she still won't wake up.
The Ditz: To the point that she has forgotten her own name several times.
Ditzy Genius: Despite her unbelievable forgetfulness, and the fact that she falls asleep when she studies, she gets the best grades out of the three girls. Not even Tsugumi knows how to explain it until she sees herself: she cannot only fight but study in her sleep.
Idiot Hair: Played with on her introduction. She has a lock of hair that she ties into a little ponytail at the the side of her head, which falls out when Tsugumi bumps into her. She redos her hair so the ponytail sticks up on top of her hair like a cowlick, though she changes it back when Tsugumi points out that that's not how she had it before.
The Mole: If her terrible memory is indeed a side effect of Shuala's mind control, then it's highly possible that Meme has been one (albeit unwittingly) for her throughout the entirety of the series
One of Tsugumi's two roommates, and a meister who is the first person to wield Tsugumi in weapon form, and is able to handle her with some impressive skill. A spoiled rich girl who is implied to have run away from home, she has trouble relating to anyone who didn't grow up wealthy, which is probably why she has such a strange obsession with commoner things. Her personality has also lead to her developing insecurities about her relationship with Anya and Meme, as she believes she can never be as close with either them as they are with each other.
Clingy Jealous Girl: Anya has a habit of giving off these vibes whenever Meme and Tsugumi are having fun without her. The most prominent example of this is seen when Meme and Tsugumi are paired up for training in class while she was left with someone else. Her reaction to all of this just screams this trope.
Defrosting Ice Queen: At first, when Anya wasn't being Tsundere toward Tsugumi and Meme, she came off as rather aloof toward them. As the story progresses, though, she starts showing her more immature and caring side.
Fangirl: Anya is a fangirl for anything "commoner"-related, indicated from her excited reaction to a regular market versus her disappointed reaction to the wealthy-looking Shibusen girls' dorm.
One of the most skilled members of the NOT class, Akane is the meister of Clay and it's pointed out by many that the pair have such impressive skill that they should be in the EAT class instead. Acts something like Tsugumi's love interest, though whether or not his interest in her is real has yet to be revealed. He reveals to Tsugumi that he is actually part of the Star Clan, the same clan Black Star is from. This is further emphasized by the fact he has a star pattern in his hidden left eye. It is later revealed that he, along with Clay, are actually Anya's bodyguards secretly tailing her: that's why they remain in NOT despite their skill.Akane and Clay make an appearance in the last arc of Soul Eater, establishing a connection between the main series and NOT.
Anime Hair: In Soul Eater Not!, his hair is quite normal, save for the big lock of hair that covers the eye that signifies his heritage. In the Soul Eater series, he seems to develop a more punky hairstyle, with more gravity-defying elements.
Bishounen: One of the few, and better looking, male recurring characters in the series.
Continuity Nod: Participates in a major battle of his own during the Battle on the Moon against one of Kishin's soldiers.
Megane: Reflects the reserved and intelligent personality that he usually displays.
Peek-a-Bangs: His left eye is covered by his hair. It's to hide the fact his eye has a star shape in it, which shows his heritage.
Voiced by: Seishiro Yamashita
Akane's weapon partner who is capable of turning into a sword. While more informal and direct than his partner, Clay is still just as level-headed and serious as Akane when the situation calls for it. While he doesn't interact with the girls as much as Akane does, he is still shown to be just as protective of them. Along with Akane, one of Anya's bodyguards.
Continuity Nod: Is part of the team that fights on the moon in the original Soul Eater series.
Ditzy Genius: Smart enough to navigate hundreds of years of archived documents for what he's looking for. Slow enough that he needs to use his fingers to figure out one plus one equals two.
Meaningful Name: His first name and the suffix of his last name put together is Claymore, which is his weapon form.
Satellite Character: In all but one chapter that Clay is featured in, he is always with Akane and what little we know of him is based on his interactions with his meister. In the one chapter that he isn't with Akane, he only interacts with Tsugumi and it just shows that he is on friendly terms with her, but finds her just as perplexing.
A weapon living in the DWMA's girls' dorm, and an upperclassman friend to Tsugumi, Meme, and Anya. Due to having more experience at the school, she is the main person the girls go to for any advice or questions about how life at the DWMA works.Eternal Feather is part of the NOT class, and her weapon form is a Butterfly Knife. It is unknown whether or not she has a meister, but nothing has been said about that matter.
Butterfly Knife: Her weapon form. She's only been seen doing a Partial Transformation, turning one of her arms into the knife, and unusually it's much larger than the full weapon form is likely to be.
Embarrassing Nickname: Thanks to Kim. She claimed that she should be called that because she's so pale looking, and unfortunately everyone else just went with it.
Meganekko: Reflects her intelligence and even gives off a motherly vibe from her.
Only Known by Their Nickname: The DWMA allows students to apply under any nickname of their choosing. Unfortunately for Eternal Feather, Kim made the decision for her. We only learned her real name when she's being interrogated but is suffering some temporary memory loss (and wishes she could still forget it afterward).
Psychic-Assisted Suicide: Under the control of Shaula, she put her own knife against her throat and slit it. Thankfully, it wasn't that deep of a cut and she got better with the help of Dr. Stein.
The Superintendent of the girls' dorm. She first comes off as a sweet and polite young woman before revealing her more psychotic side to Tsugumi. She wants nothing more than for Tsugumi to act like her precious Mary Smith, a character from her favorite novel. It is currently unknown how Misery is ranked as a student, or whether she's a meister or a weapon.
Ax-Crazy: Comes to be expected when you're based off Annie Wilkes. To put it into perspective, she's disappointed that Tsugumi doesn't act enough like her favorite character and so decides that the only way to fix that is to go into Tsugumi's room at night and try to fix her with a hammer.
Expy: Of Annie Wilkes; she's even named after the movie/book the character is from.
Fangirl: A fan of a certain book series and adores Tsugumi because she looks like the main character. When she discovers Tsugumi doesn't act like the character she decides to fix it with a hammer.
Serious Business: Her name should give you an idea of how serious she takes her books.
The resident fortune teller in the girls' dorm. Altair is very direct about her fortunes, not even holding back when she tells a patron that their future may have a bad turn. At this point,it is unknown what her class standing is, or whether she's a weapon or a meister.
Fortune Teller: She mainly uses tarot cards to make predictions whenever someone asks, and while a lot of them are direct and even mean, they're mostly true.
Emotionless Girl: It's hard to tell if she's truly emotionless or just passive aggressive. When telling Anya's fortune she seems to enjoy watching Anya freak out at being dealt bad cards.
