Righto, since we're apparently talking an assault on Asunaro at some point, I figured I would at least write up a threats list first. Using my extremely rusty knowledge because fuck you not reading it again.
Kazumi/Michiru Kazusa/Kazumi Subaru
Wish: To let her grandmother live long enough for them to make peace./To obtain a human body.
Personality: Bubbly, childish, and not particularly bright, but earnest enough and basically a good person. Think Season 1 Sailor Moon. Possesses no memory of her original self. Has an obsession with food (specifically risotto and parfait) that borders on the fetishistic. Gets pretty angsty once realizing her true nature. Matures (somewhat) after the series. As Michiru, she was apparently so beloved by her team that I can only assume she extruded magic pheromones. Do not waste food around her.
Abilities: Kazumi is basically a big pile of raw destruction. Her weapon - a giant cross - can fire lasers powerful enough to annihilate witches. Most of her other abilities, including the creation of muskets and bonds, can best be described as Mami-lite. Under certain circumstances, she may revert to a witchlike form (though this takes time, so don't expect her to do it mid-combat).
Fashion sense: Going Commando/10.
Umika Misaki
Wish: To get a better editor.
Personality: A fairly successful writer, who uses the money she obtains in her career to support the others. The smart one of the KM characters, which is a bit like being the beauty queen of the third-degree burn clinic. Has the generic personality that all smart people in manga have. Imperious and proud, but otherwise basically sane. Put the memory spell over the town.
Abilities: Umika is pretty dang hax. Her weapon is a book (GET IT BECAUSE SHE'S A WRITER) that can read an enemy's thoughts and actions, analyze something's weaknesses, copy certain techniques, and turn into a two-bladed spear. She can also manipulate and remove memories. If it comes to it, take her down first.
Fashion sense: Nun/10.
Kaoru Maki
Wish: To heal the people she injured playing soccer (which is what it is called in Japan, shaddup).
Personality: Where Umika is The Smart One, Kaoru is The Sporty One. Spunky, strong-willed, and athletic. Guilty about injuring others, but not about kidnapping megucas and locking them up. Umika's girlfriend, probably.
Abilities: Very strong and agile, particularly in the legs because soccer. Weapons are cleats, because soccer, a ball that she kicks like a cannonball, because soccer, and a staff that she never uses because not soccer. And now the European SV users are sharpening their own cleats at me, so I'll move on.
Fashion sense: Painted On/10.
Saki Asami
Wish: That the flower owned by her dead cousin would bloom forever. Kyubey presumably spent the rest of the day laughing his ass off.
Personality: The Tough Girl, pulling double duty as The Commander Girl. Reasonable enough, I guess, if you don't mind the creepy incestuous undertones. Seems to have been closest to Michiru, to the point that even her witch form ignored orders to attack Kazumi (however, these were not normal circumstances, so don't count on it).
Abilities: Has a riding crop that shoots lightning and can turn itself into some kind of vine. She can also speed herself up or slow herself down. All these powers, I'd imagine, come in very handy in bed ha ha ha kill me
Fashion sense: You Know Maybe Tight White Pants In A B&W Manga Is A Bad Idea/10
Mirai Wakaba
Wish: Teddy bear museum. This is canon and I hate you all so much.
Personality: Immature and proud. Also a yandere for Saki. Goes berserk whenever Saki is injured. None too bright, even by Kazumi standards. Obsessed with teddy bears. Avoid poking.
Abilities: Wields a staff that can shoot fire and turn into a giant pink greatsword. Can conjure up teddy bear troopers, in both "horde" and "boss monster" varieties.
Fashion sense: Pink Fluffy Senketsu/10.
Satomi Usagi
Wish: To talk to animals hey wait where are you going
Personality: Outwardly, friendly animal-lover. Inwardly, homicidal loon who wants to kill the clone, as well as the others, and break the cycle. Unstable, do not annoy. Not sided with Hijiri, merely a rogue element.
Abilities: To talk to animals (duh) and mind control. Fortunately, it's that kind of mind control where you can break it by thinking really hard about how much you love your friends. Weapon is a wand with a cat head.
Fashion sense: Catgirl/10.
Niko Kanna
Wish: To create another version of herself to live out her own life.
Personality: The mad scientist of the group, having created Juubey and orchestrated the Kazumiclones. Quiet and rather emotionless. When she was young, she played with a loaded gun and accidentally shot her friends, and her wish was designed to help her cope with the guilt - the clone would lack her own memory of the event, and she gave it her original name while changing hers. Seems very affectionate toward Kazumi. Probably the most useful member for us, which is why she's also first to perish, witching out after battling the Soujus.
Abilities: Reconstruction of matter. Her weapons are a wand and CD-shaped shuriken, but she rarely uses them, favoring her reconstruction ability to create clones of herself, heal others, or turn parts of her body into weapons. She can also combo her powers with Kazumi's to create some kind of lesbian laser beam.
Fashion sense: Goggles/10.
Yuuri/Airi Anri
Wish: To become a clone of the girl Yuuri Asuka, so as to get revenge on the girls. Jesus, what is it with this fucking manga and clones?
Personality: Remember Nie from Resonance Days? Yeah, she's nowhere near as cool here. Basically your standard vengeful supervillain. Fortunately, It Was All A Big Misunderstanding and they aren't actually responsible for her death. Psychotic, gloating, the works. Not especially useful, though talking her around could work. Was given Evil Nuts by Hijiri. Really liked Yuuri. No, I mean the girl Yuuri. But she also liked yuri.
Abilities: About fifty of them. Weapons are magic guns similar to Mami's (though they're more modern-looking). Can also conjure up a giant bull to fight for her. Can also create force fields, change her appearance, and make explosions. Pretty hax, but not so hax that Sabrina couldn't take her apart.
Fashion sense: Cutie Honey/10.
Luca/Ayase Souju
Wish: Unknown.
Personality: A set of twins with half a personality between them. Luca is the calm one, Ayase is the hot-tempered one. Probably the most well-known Kazumigirl, and probably the most irredeemable, since they have no real backstory. They wander around collecting Soul Gems because... well, they're pretty, apparently, and they need a hobby. They're all about brute power, and required two MGs to put them down. If we see them, no one will miss them... though that trick of theirs is pretty nifty.
Abilities: Two MGs share a single body, and can switch between two powersets. It's unclear if this is something only they can do, or if any MG could do it with proper training. Luca has ice powers, Ayase has fire powers. They can also synchronize their powers to create a big blast of sisterly love, which I think is how Frozen ended.
Fashion Sense: Rule 63 Two-Face/10.
Kanna Hijiri
Wish: To connect to others without them knowing.
Personality: The most overtly supervillainous of the bunch. Kanna has two plans: kill the Pleiades Saints for revenge, and WORLD DOMINASHUN. She hates everything because she's a clone and not real a bloo bloo bloo, and wants to make a world full of artificial people like herself, believing that Niko created her as a doll. The fact that Niko gave Kanna her original name while changing her own apparently never crossed her mind. Bombastic speeches, pointless sadism, and over-the-top antics are the order of the day with her, but it's nothing a friendship speech can't solve.
Abilities: Her weapons are strings (think Walter from Hellsing), but her powers are the real worry. They basically amount to "anything you can word as a connection." So she can insert herself into people's memories because she's connecting to them. She can control witches because she's connecting her will to them. She can merge witches together into an IKEA Walpurgisnacht because she's connecting witches to each other. She also has all the powers of the other Saints because she's connecting their powers. She can also create Evil Nuts because I give up. She's basically the equivalent of schools that insist that they have a balanced menu because ketchup is a vegetable.
Fashion Sense: Jeff Bridges In Tron Legacy/10.
