For those unfamiliar with this anime...

Professor Negi Springfield-age 18 (for all intents and purposes). Light brown/reddish hair, wears tiny glasses. Negi is a teacher at Mahora Academy, but he's also secretly a wizard. He can't let anyone know he is, or not only will he never become a 'Magus Magorum' (a full-fledged ranking wizard), he'll also lose his magic certification and be turned into an ermine (or perhaps a chupacabra?). He's been teaching the same group of girls since they were all in 13 (he was 10 at the time), and most of them have grown to love him to some degree. He's from Wales, but speaks Japanese so fluently, his accent is all but gone. He has crushes on Asuna and Nodoka.

Asuna Kagurazaka-age 18. Orange-red hair, blue eye, green eye. Mid-B cup. Keeps her hair in long twin ponytails tied with small bells. She is Negi's roommate before he vanished for an unknown reason. She likes him more than she'll admit, but it's still only a friendly like, almost motherly in some ways. She and Ayaka have been friends-but-enemies since childhood and have only recently acknowledged friendship. She has a temper, but is generally a nice person. Asuna is fiercely loyal to her friends and very protective of Negi.
Pactio artifact-Demon-banishing paper fan (called a harisen) that can become a big sword in certain circumstances.

Konoka Konoe-age 17. Brown hair past her waist. Small D-cup. Konoka is Asuna and Negi's other roommate. She likes Negi like Asuna does, she's just more open about it. She has within her a strong magic power that has been held dormant for years. It was released once, but never since.
Pactio artifact-?

Ayaka Yukihiro-age 18. Blonde hair the same length as Konoka's. Mid-C-cup. Asuna's lifelong friend/enemy. Rich girl with a bit of a chip on her shoulder, though only around Asuna. Likes Negi a lot, but mostly in an 'isn't he cute' kinda way. It's a crush, really. But now that they're the same age, Ayaka realizes he's no longer the boy she knew, but is a man. This should take her fondness for him to a new level...
Pactio artifact-?

Nodoka Miyazaki-age 17. Shoulder-length purple hair, blue eyes. Small C-cup. Nice and sweet but VERY shy. Negi has 'very cute' written by her picture in his roster book, and it suits her. She has been in love with Negi for four years when this story begins, but they're never dated or kissed other than a Pactio (a spell to bind her in a temporary partnership with Negi as his Ministerial Magi, or wizard's assistant). She wants him more than anything, but it makes her sad to have to compete with her friend Yue for him.
Pactio artifact-Picture-diary that shows her the thoughts of anyone who's name she calls out. Her 'rare' card gives her a collection of magic books that contain a sort of database of all the world's knowledge and information.

Evangeline A.K. McDowell-apparent age 15. Long silver-white hair, green eyes. Mid-A-cup. A vampire defeated by Negi's father and bound to Mahora Academy, Eva is far older than she looks, unless she uses a spell to make herself look her true age (or maybe a decade or three younger). Eva is as good a magician as Negi, and the two are in a sort of brittle truce. Negi has promised to break the curse on Eva, but so far he hasn't, or couldn't.
Pactio artifact-I wouldn't hold my breath for Eva to kiss Negi.

Chachamaru-age 10, apparent age 16. Long green hair, antennae. Mid-C-cup. Evangeline's robot bodyguard, companion and housekeeper. A magically animated robot/golem hybrid, Cha-Cha has no feelings for Negi except curiosity. Chachamaru is equipped with high-tech weapons and information gathering systems, all at Eva's disposal. She talks with the kind of monotone cadence of a robot, but her voice is very soft and has a trace of British accent. Chachamaru has recently undergone upgrades to make her look more like a high school student. Not only that, she's also gotten a new, very life-like 'skin', which covers her joints, as well as features new 'anatomical corrections'.
Pactio artifact-none. robots can't make pactios.

Yue Ayase-age 17. Blue hair, always looks uninterested. High A-cup. Nodoka's best friend and rival for Negi's heart. Despite her low test scores in class, she's not really stupid, she just doesn't want to study. Since Negi's first year, Yue has had a crush on him, though it hurts her to compete with her best friend of several years for him. She may end up letting Nodoka have him again, but then again....
Pactio artifact-A small wand that allows her to do a very limited version of some of Negi's magic.

Fuka (small-C-cup)and Fumika (mid-C-cup) Narutaki-age 17. Pink hair. The cunning twins who once placed a prayer for Negi's love. They both love to play tricks on people, and have an unspoken but obvious bond. Very cheerful personalities, they want Negi both to love and just to have fun with. Ever since turning 16, they've become more introverted, spending lots more time alone together in their dorm. I wonder what they're doing in there.....
Pactio artifacts-Eastern and western detectives. But what does it do? Well....to be honest i don't know. i've never seen them in use, so i really couldn't tell you what they do.

Fei-Ku-age 17. Blonde hair, tan skin. small C-cup. A martial arts expert, Fei-Ku is very self-confident and energetic. She likes Negi, but not too bad. She's not exactly praying for his love, but she wouldn't mind it, either. Originally from China, her Japanese has vastly improved from the 'cave-woman talk' of the manga, but it still isn't quite perfect. Things that would be contractions still somehow escape her.
Pactio artifact-?

Setsuna Sakurazaki-age 18. Dark blue hair tied into a long tail on her left side. Mid-C-cup. A master swords woman, Setsuna was assigned by the dean of Mahora to protect his grand-daughter, Konoka. They've been friends since early childhood, and may have feelings beyond that....use your imagination.
Pactio artifact-Better, though similar sword.

Kaede Nagase-age 17. Dark grey, almost black hair. Mid-D-cup. A kunoichi (female ninja) who is one of only five students who know Negi's secret of sorcery (The others are Asuna, Eva, Chachamaru, and probably Nodoka. It'd be weird if she didn't know), Kaede likes Negi in a platonic way, but that was before she saw him at her own age. Now, all bets are off for the lone forest-dweller.
Pactio artifact-Fox costume/ability to transform.

Sayo Aisaka-apparent age 15. Pale all over, white hair. Bra size not important, since she's dead. A ghost who died many years ago, her soul is stuck in Mahora. She doesn't mind, and finds all the constantly changing students fascinating. She died trying to keep her sister's flower garden from washing away. She's too young in mind for romance, but she likes Negi as a friend and about the best teacher she's seen.
Pactio artifact-?

Kazumi Asakura-age 18. Dark spiked red hair. Mid-C-cup. An amateur paparazzi, Kazumi always has a camera close at hand to make sure she never misses a chance at a great picture. Negi would have done well to watch out for her when using magic if he wants his secret kept, but it wasn't to be. While saving a cat from being run over, Negi used a spell while Kazumi was watching, so he was **** to make a pactio with her. She's recently been hanging around Chisame a lot more. Could there be some less-than-friendly, or perhaps even more-than-friendly, reason for this? An internet idol and a photographer. There are several things that could indicate, but Chisame's site has seen a massive boost in photo quality...
Pactio artifact-Robotic cameras that operate from anywhere and send what they see and hear to a hand-held monitor.

Chisame Hasegawa-age 18. Long green hair. Low D-cup. Innocent schoolgirl by day, internet goddess by night! Having turned 18, Chisame has changed her website from cosplay to full-on porn, though it's only been solo things so far (or has it?). Lately she's been getting a lot of requests on her message board to broadcast her own defloration, and she's strongly considering it. It would send subscriptions through the roof, after all. The only problem is, where to find a man in an all-girl's school. Hmm, where indeed?
Pactio artifact-?

Haruna Saotomi-age 17. Long green-brown hair. High C-cup. Nodoka and Yue's friend. Less of a bookworm than they are, more of an artist. She spends a lot of time drawing manga, but since Yue and Nodoka became 16, she's shifted from action manga to yuri (lesbian hentai) starring characters that look suspiciously like her friends. One featured the defloration of her version of Nodoka, named 'Meiko', by a character that resembled Negi, named 'professor Silverburg'. Her two muses have no idea she drew these. Haruna likes Negi in a 'yeah, hes alright' way, but now that he's her age, she's sure to find herself thinking about him differently. Haruna has the pseudo-psychic ability to 'smell' when people are in love. She says it smells like dried almonds. It's never wrong.
Pactio artifact-Drawing pad and pen that can make what she draws real.

Makie Sasaki-age 17. Shoulder-length pink hair. Low B-cup. A cheerful, if not exactly brilliant gymnast, Makie's fondness for Negi has grown ever since Asuna's 13th birthday party (the last episode of Negima!). Now that she's older and has a basic understanding of sex, she's eager to find out everything about love, romance and sex from Negi.
Pactio artifact-Ribbon that acts as a whip and can bind enemies.

Mana Tatsumiya-age 18. Long black hair, dark skin. Mid D-cup. A gun nut/Shinto priestess. I wouldn't call her rude, but she has no tolerance for wasted words, or wasting her time.
Pactio artifact-Not sure, but my money is on some type of gun.

Zazie Rainyday-age 17. Short almost-white hair, two markings a tear and a 'scar' through her eye, on her face. Mid B-cup. A magician, but more like an amateur, low-budget David Copperfield than one like Negi. Card tricks, birds from nowhere, things like that. Aside from her quietness (she has one line in the entire first Negima anime), her most recognizable trait is her almost vacant stare. Her eyes never open more than half-way, for anything. It's almost like she's seen everything happen a hundred times already and is bored with it. She's also the star of Mahora's Acrobatics club.
Pactio artifact-?

Shinobu Maehara-age 18. Shoulder-length purple hair, blue eyes. Very Nodoka-ish. If you've seen Love Hina (yes, it's that Shinobu), you know what the score is. A while ago, she fell in love with an older boy who loved someone else. Eventually, they left the lodge they, Shinobu and several other crazy characters stayed at. After they did, Shinobu couldn't bring herself to stay there without him, so she saved her money and traveled around Japan, eventually running into dean Konoe, who, sensing her despair, bought her a beef bowl and listened to her story. So moved was he that he offered her half-price tuition at Mahora, payable whenever (like Asuna), so she could start over without being reminded of her lost love, Keitaro. She keeps in contact with the girls over at Hinata Inn, so one or two of them might stop by.
Pactio artifact-I'd kinda like to know that too. Should be interesting...

Professor Takamichi Takahata. age 38. A veteran teacher at Mahora. For as long as she's been at Mahora, Takahata has been the object of Asuna's affection and her dreams. He however thinks of poor Asuna as more of a daughter than a potential lover. Ayaka, on the other hand.....Takahata is a helluva fighter, can use both magic and chi (to some extent) and is known and feared by the punks around Mahora as '****-Specs'.
Pactio artifact-N/A

Albert 'Chamo' Chamomile. age unknown, presumably an adult. Chamo is an ermine elf. To put it another way, he's a talking, smoking, panty-stealing, advice-giving ferret-type creature. Very easy-going and a loyal friend to Negi (unless it's dangerous), Chamo was the driving **** behind Negi's infamous 'partner-drive' in his first two years teaching. His motives however were not simply to play match-maker. He gets a 50,000 ermine dollar (i don't know what those are either or how he spends them) for every partner ('Ministel Magi') Negi enters into a contract with. None of his former partners (see below for the list) knows it, but their contracts were only binding until Negi became an adult. Now that he is one, the contracts are null and he can now have only one partner. Who will it be?
Pactio artifact-N/A

Nagi 'Thousand Master' Springfield-age and whereabouts unknown. Is he even alive? Maybe....

Notes:
-all the girls wear blue and white uniforms that are different from the ones in the anime. this is because they're in high school now. if you've seen the volleyball episode, they now wear the same uniforms as their high school opponents. if not, well....i don't know what to tell ya other than the uniforms are blue and white.

-ages and projected bra-sizes are guessed and other details are from memory. inaccuracies are a real bummer, but i'm not THAT into making this perfectly right.

-the anime and manga have some differences, and for the most part i'm going by the anime, since i've seen more of it than i have the manga.

-please excuse any inconsistencies. i'm basically improvising this story as i go and don't have any idea how things will turn out until i write it. i like to think this makes it unpredictable like real life, but it also lends itself to plot holes. i'll correct what i find, but if i miss one, try to let it slide.

-i've made more than just a couple references to a group called 'the Baka ('idiot') Rangers'. this refers to five of the girls, each of whom is also called by a second 'Ranger' name. the Rangers are Yue (Baka Black), Fei-Ku (Baka Yellow), Kaede (Baka Blue), Asuna (Baka Red), and Makie (Baka Pink). this group is so-called because of low test scores and in Makie's case, sheer airheadedness. if you're more familiar with the dubbed version, the Baka Rangers are also called 'The Idiot Brigade'.

-i've recently seen about half of the episodes of Negima?!, a 'second' Negima anime. i'm going to take a couple liberties with Negi's partnerships. On Negima!, only Asuna was ever his partner and remembered at the end. On Negima?, everyone wound up Negi's partner at then end of episode 14. in Crono04 presents: Negima, at this point, Negi's partners have been/are: Asuna, Nodoka, Setsuna, Kaede, Yue, Haruna, Kazumi and very briefly Makie. Makie turned out badly, and Negi nullified the contract and erased her memory of it. Several others know his secret, but have agreed to keep it secret.

-i will on occasion be using terms that don't exactly make sense, but i assure you there is reason for them. i've been watching Negima in subtitled form and when i think it works better or is just funny, i'll use the more literal translations. the most common example will probably be Nodoka's nickname 'bookstore' which is a more direct translation of the one given in the Japanese version (honya-chan). this will hopefully give this story more of the feel of watching an episode, which will help you the reader visualize what i'm writing. i won't use honorifics like san or kun like they do in the anime or manga, after every name. but i will use their basic translations when i think they're needed. i won't say 'Negi-kun' every time, but if someone would call him 'Negi-bozu (Negi-squirt), i'll use 'Negi-squirt' or 'Negi-brat'. i will keep sensei, however, because i think it's a good way to show how some of the girls feel about Negi. plus i think Nodoka gets off on calling him that a little bit.
if it helps, assume everyone but Asuna is calling him Negi-san (Asuna simply calls him Negi). but:
Negi-kid, -squirt, -shrimp or -brat=Negi-bozu
Negi-boy=Negi-kun
Evangeline will sometimes call him 'boya', which is like 'bozu', but meant to be disrespectful and condescending.
Also, since Takahata is so much older than the others, he refers to them as younger. So:
-boy=kun (as in Negi-boy=Negi-kun)
-girl=chan (as in Asuna-girl=Asuna-chan)

-Pactio cards. Basically, when someone makes a pactio, or probationary contract with Negi, she is given three cards. Which card Negi draws when activating the contract decides what the partner can do. after using a card, the partner changes back to normal, but very hungry and weak until fed. i'll explain the cards as best i can.
Appearance: Bigger than playing cards, more like tarot cards. They have a picture of the girl on them along with some info about them, like their alignments and things like that.
Types: Cosplay, Rare,
Cosplay Card: The most common type. These are the 'standard' cards. Unless otherwise noted, assume that when a contract is activated that a cosplay card has been drawn.
Rare: These are the highest grade of card and grant the most power. If Negi draws a rare card, the battle will almost certainly turn in his favor, regardless of the opponent. However the odds of this are low, hence the name.
__: These cards are a bad sign. They change the partner into a baby-sized version of herself in an animal costume. When a card is drawn, they become even more powerless than they were before the contract as active. Basically, if he draws this type of card, Negi is on his own AND has to guard the partner.
one more thing: on some of these character explanations, i put 'Pactio artifact-?', even if i do know what it is. This is so the reader, if they don't know, will have to decide on who Negi's partner will be without knowing the result, which will hopefully add some suspense and interest to the story. The ones i wrote out are the ones Negi knows what they'll be.

-if you plan on adding to this story (which i guess no one has yet, so this is probably moot), please try to keep it light hearted as much as possible. not trying to tell you how to write, but if you plan on making this really dark or REALLY unlike the anime (like, say, Chachamaru rapes Evangeline or Konoka and Nodoka do a drive-by on Negi), there are probably dozens of more appropriate stories on this site that would fit what you wanna say much better. that said, i know this whole story isn't mine, but writing a Negima story is fun for me, and it'll be difficult to continue from something like what i said above.

-i'm assuming characters not from Japan speak in Japanese but think in their native language. for example, while Fei-Ku speaks a bit roughly sometimes, in her own mind she's using Chinese, so she speaks well. also, if you're imagining the voices as you read, Negi and Chamo have their accents.

Important terms:
Magister Magi-A term used for full-fledged wizards who have graduated from magic academy, passed their probationary period (in which they have to be among normal people while keeping their magic a secret) and has a Ministra Magi. Takahata is a magister magi; Negi is still on probation, though his probationary period is almost up.

Ministra or Ministerial Magi-A Magister's partner, back-up and companion. The Ministra's job is to protect the Magister with hand to hand combat while the they prepare spells and are **** to attack. A mage and their partner are bound into a magic contract through a brief ceremony called 'pactio' (more on this later), and the ministra is given power from the magister, as well as a unique artifact. What the artifact is depends on the partner. For example, Nodoka, a quiet librarian, got a book that reads thoughts.
Magisters are almost always of the opposite sex as their ministra.

Pactio-This is the ceremony that binds magister magis to their partners and vice-versa. It's done by first drawing a magic circle, then having the two being bound stand in it and either kiss each other (the preferred method) or exchange blood. Once done, the ministra is granted powers borrowed from the magister which increases their strength, speed and reflexes, as well as giving them an artifact.
