The Heroine of the series, an optimistic, kind-hearted and very energetic girl attending a One Gender School. She's devoted to her hometown and to the duties of the Jersey Club, of which she was its sole member. When given the choice to pilot the Humongous Mecha to protect Kamogawa, in a change of pace she readily accepts, maintaining her usual cheerful demeanor the entire time. She rides the Vox Aura, a wind-elemental machine she calls "Midori", which was later armed with a sword and an energy shield.
Accidental Misnaming: She can't seem to remember Villagiulio's name. Practically a Running Gag. In Season 2, she opts for "Giuvi-nii" instead. Still wrong, though.
Accidental Public Confession: In Episode 18, while trapped in an escape capsule in Yurikano's body, Madoka hits the emergency transmitter, causing her to broadcast her musings to everyone in the ongoing space battle. Said musings include the reasons behind Yurikano's sacrifice. She also lets Lan and Muginami know that she's actually Madoka, through a variation of "No One Else Is That Dumb".
Badass Adorable: Energetic, lively, friendly, and more than ready to fight to defend her friends and hometown.
Batter Up: Madoka bats away a flying newspaper dispenser, using a ripped from the ground streetlight.
Berserk Button: Don't even think you can get away with insulting or harming her comrades.
Catch Phrase/Verbal Tic: Madoka always says "maru", which means "Tick", "Circle" or "Perfect" in English. (So named because "O" is right and "X" is wrong in Japanese game shows) Which may also be a pun on her name, which can also mean circle.
Cloudcuckoolander: She doesn't find anything wrong with going to school in her swimsuit.
Combat Pragmatist: Madoka uses a ripped electrical line to try and choke Kirius' Ovus Libertas. Of course, since it's a robot, it doesn't do any good, though, it drove Kirius into a panic attack, thinking the ineffective choking might be a "finishing move" he doesn't know about.
Crazy-Prepared: Madoka just happened to wear a swimsuit under her school uniform the day she sees someone drowning.
Cry Cute: At the end of Season 1, the otherwise energetic, cheerful Madoka struggles to complete her Character Tic through tears before breaking down crying after she sees Lan off, leaving her all alone (with Muginami having already left earlier).
Famed in Story: By Season 2, everyone knows of her exploits in defense of Kamogawa. Some (female) patrons in Hiroshi's beachside restaurant even blush when they see her. This also applies to Kirius and friends to some degree. At the end of the series she even receives a call from the Secretary-General of the United Nations.
Fashionable Asymmetry: When wearing her jersey (i.e. pretty much all the time), Madoka has the right leg and left sleeve rolled up.
First Name Ultimatum: Madoka doesn't like it that her uncle is drinking in daylight, especially with a complete stranger.
Jumped at the Call: As long as it helps her friend, Madoka doesn't mind piloting a robot for the first time in her life to defeat alien forces. Which is pretty refreshing compared to other mecha heroes.
She briefly gets upset when she has to pilot again at the start of Season 2, but she quickly gets over it.
Nice Girl: Unconditionally kind to everyone and anyone. Then again, one has to wonder if she really has any other friends aside from Lan and Muginami (which is confirmed in Episode 10).
Nice Job Breaking It, Hero: Activating the Rinne the first time was obviously a very bad thing. And when she does it again, the world basically ends up in the crapper. She doesn't intend to, but it still qualifies.
Missing Mom: It's established her mother drowned ten years ago when she tried to rescue someone. Episode 24 reveals that in her desperation to see her mother, Madoka tried to head out to sea, only to nearly drown were it not for Vox Aura's appearance, which to her is a sign from her mother telling her to live on.
Percussive Maintenance: In Season 2, she reactivates Aura by hitting it. It's implied that it only activated that way because she wanted to, rather than because it was necessary.
Madoka's first alien friend, a strange and quiet girl who happens to be a princess from a faraway planet. Lan essentially serves as the antithetical counterbalance to Madoka's blatant cheerfulness. She pilots Vox Rympha, or "Orca" as she calls it, a water-elemental machine later armed with a sword-machine gun hybrid which can fire 120mm shots and energy shield.
Rei Ayanami Expy: Blue-haired, pale-skinned alien Humongous Mecha pilot with a stoic demeanor that makes her come across as emotionless at first. She's a variation in that her stoic facade is much more easy to crack than most examples and she defrosts notably quickly.
A mysterious, yet ultimately somewhat ditzy and idealistic girl and adopted younger sister of Villagiulio. Despite her cheerfulness, she hides quite a sad side to her. She is the pilot of Vox Ignis, or "Fuupo" as she calls it, a fire-elemental mecha armed with a pair of energy guns which she can fuse into a sword.
Badass Cape: A later upgrade to her Vox Ignis come Season 2.
Because You Were Nice to Me: Part of the reason she respects Villagiulio. Also inverted, since they first met when she gave him part of her apple which was barely anything more than the core, and the only food she had.
Big Brother Worship: For Villagiulio, to the point where she voluntarily brands herself with a Memoria mark, even though they are Not Blood Related. Of course, considering that he was probably the only friend she ever had prior to meeting Madoka and Lan...
Caped Mecha: Ignis becomes this in Season 2, using an energy cape as a shield.
Replacement Goldfish: Suspected, but averted. When Yurikano and her past begin to be revealed (and then the person actually comes back from the dead... sort of), Muginami worries that she may be but a replacement in Villagiulio's eyes. He ultimately tells her that she is unique, and he would be her big brother as long as he lives.
Madoka's older cousin and a tough woman who refuses to let crap get to her, or anyone for that matter. Appears to know a bit more about the Vox units than she should, given her profession. She was also the original founder of the Jersey Club before Madoka took over.
Parental Substitute: Served as this to Madoka after her mother died, and taught her an astonishing amount of her "jersey spirit". It's quite the surprising change to see her with the front ponytail and jersey when contrasted with her brash and mellow personality.
The granddaughter of Novumundos' chairman. In fact, she's the one inadvertently responsible for the disaster 20,000 years ago, and is now finding ways to at least repair some of the damage she has unwittingly caused under Balance T. Moid's warping influence.
The Atoner: For causing the disaster of 20,000 years past.
Covert Pervert: Really seems to be a well-composed and elegant young lady... then starts groping Madoka with relative consistency. Gropey-ojou indeed.
She even embarrasses Madoka with naughty comments. For Science!
The main antagonist of Season 1, older brother of Muginami (adopted) and Yurikano (true-blooded), and the former crown prince of De Metrio turned leader of outlaw organization "Kiss". For some reason or another is quite into capturing the Vox units. By the time Season 2 starts, he returned to his home world and ascended as king. He pilots the Ovus Avarium, a heavy-duty mecha armed with a pair of anchors stored in each arm, a pair of large swords, and a large mortar gun.
Noble Fugitive: He's a deposed prince. Subverted in Season 2, where he takes the throne of De Metrio. Then at the very end he formally abdicates to spend more time with Dizelmine and help mend their broken friendship.
The rather Hot-Blooded, rebellious but caring member of the trio from De Metrio's forces who have made an alliance with Kiss. He pilots the Ovus Voluntas, a close-range machine using a pair of heat clubs and a force field for defense.
Team Chef: His job when he begins working on Earth.
Wrong Genre Savvy: Watches a samurai movie, then tries to challenge Madoka on a duel repeating what he saw, never realizing that he accidentally fooled the entire school into thinking that he's her boyfriend.
The more stoic member of the trio from De Metrio's forces who have made an alliance with Kiss, as well as the oldest and most sensible of the trio. He pilots Ovus Libertas, armed with a metal staff, heat-based whip-swords, and an energy field.
The third member of the trio from De Metrio's forces who have made an alliance with Kiss, as well as the youngest and most effeminate of the three. He pilots Ovus Teneritas, armed with a pair of shoulder cannons and a force field.
Attractive Bent-Gender: He passes off as a girl so easily it's a genuine surprise when he turns out to have been the maid the whole time. In Episode 9, some guy even starts flirting with him even after being told he was a guy. Season 2 continues this well-founded tradition of confusing him for a girl.
Villaguilio's true-blooded younger sister with some feelings for Dizelmine and was previously betrothed to him, who apparently perished in an incident a few years prior to the start of the series.
Ace Pilot: Apparently, she was one before her Heroic Sacrifice. When her soul is brought back to the world, she says her skills have apparently dulled somewhat... but she's still damn good.
All There in the Manual: Dawn of Memoria, a Prequel manga with an initial focus on Yurikano, actually began serialization before the anime aired. This makes her appearances in Season 1 somewhat less confusing for Japanese viewers who were reading the manga.
Back from the Dead: A double-subversion. It's just a matter of a well-timed "Get a Hold of Yourself, Man!" moment in the Rin-ne to bring her soul back to the body. Unfortunately, the method used has a rather nasty side-effect. She disappears once more... only to return for good at the end of the series, after Madoka and friends convinced her to stay in the material world with Dizelmine.
Barrier Maiden: Her presence in Rin-ne allows her to intervene when Madoka tries to use the full power of Vox Aura.
But Now I Must Go: Even after her revival, she vanishes completely. She tries to disappear again in the finale, so she could stay with Dizelmine in the Rin-ne. Madoka convinces them to return to the realm of the living.
Genki Girl: During her happier days at the Dawn of Memoria manga.
Heroic Sacrifice: To stop the war between Le Garite and De Metrio, she traps her own soul inside the Rin-ne. Forever. She's nonplussed to find out that somebody is capable of accessing Rin-ne through Vox Aura.
Laser-Guided Amnesia: Subverted. Her memory is not "lost" — her soul is not there to begin with due to being trapped in the Rin-ne.
Posthumous Character: She's already dead via Heroic Sacrifice before the beginning of the series. All Polyhedron characters except Grania has a fond memory of her. Then someone with her exact likeness appears. Then it's revealed that it's really her body, without her soul. And then her soul is brought back to Madoka's body. So she's not virtually-dead anymore. And then she Disappears into Light so she's virtually-dead again. And then she comes back for real at the end.
Royals Who Actually Do Something: Izo, Kirius and Array are equally surprised to learn that she is their student-instructor during their academy days in Dawn of Memoria.
Something Only They Would Say: When the De Metrio trio encounters her in Madoka's body, they ask her to do this to prove her identity. When she later speaks to Villaguilio, she becomes Genre Savvy and does this trope without prompting.
You Are Worth Hell: Defied! She want to stay in the Rin-ne with the comatose Dizelmine to atone for the extreme damage they caused to the worlds, but Madoka and friends bring them back to the materium.
Reasonable Authority Figure: After Villagiulio is incapacitated and Dizelmine clearly loses his mind, she immediately arrange a ceasefire with Le Garite. It's not worth winning the battle if a cosmic cataclysm is just on their doorsteps.
Subordinate Excuse: Has a pretty obvious crush on Villagiulio, which he prefers to ignore.
Anti-Villain: More than willing to make other peoples' lives a living hell so long as that means his own citizens are safe.
The Atoner: According to Astelia, his Plot-Relevant Age Down at the end of the series carries the implication that he may have wished to turn back time so he can set right every wrong he made — the same wish Astelia herself made that turned her into what she is today.
Be Careful What You Wish For: He badly wants to discover what's inside the Rin-ne, even if that causes an apocalypse? Guess what, he got his wish... right after it accepted Madoka's marching song (which he deems dreadful) as its voice.
Even when he's yelling at Tadokoro because he wants to watch the Flowers.
It's even joked about in the Omake for volume 4. Apparently, while Moid would be quite handsome with his eyes open, it would also herald the End of the world. Of course, this is most likely Dizelmine having a joke at Lan's expense.
A student in De Metrio's Royal Air Force Training Academy, she is in Yurikano's class along with Izo, Kirius, and Array. Sanu soon finds herself on the run from the military due to the fact that she possess a Memoria with an unknown Vox.
