One boy + Thirty girls? Oh, you better believe there's some teasing going on!
Ship tease more or less makes up Konoka and Setsuna's entire relationship. Setsuna obviously has an attraction to Konoka, but it's impossible to tell if all of Konoka's flirting is because she's too innocent to notice, or whether she's trying to seduce Setsuna and Setsuna just isn't catching on.
By far the most aggravating instance was the Almost Kiss between Setsuna and Konoka, when Asuna interrupted them while they were about to perform a Pactio. Ken Akamatsu is cruel.
Negima!? NEO. Lesson 29. The focus? Konoka and Setsuna. The apparent plot? Very condensed version of the Kyoto Arc, except with Konoka and Setsuna travelling alone. Setsuna is of course, blushing a lot since the two are alone together. The actual plot? Konoka setting the entire thing up so that she and Setsuna could share a romantic kiss like they promised to when they were kids. The sound you just heard was the combined Squee of KonoSetsu shippers. It was scanlated ahead by ten chapters for a reason.
Chapter 252 of the manga is even worse (or better), being a giant ship-tease-turned-relationship-upgrade-of-sorts for the duo. Konoka, who was for the entire chapter was very, very enthusiastic about the pactio, finally make the damn thing with Setsuna. Chamo times it and confirms it as the longest pactio kiss yet. They're pretty much as close as possible to being an Official Couple without actually being one.
Post-pactio, even Jack freaking Rakan jumps in on the shipping bandwagon, going so far as renaming a powerful sword technique just for Setsuna. Konoka seems to be happy about it though...
Jack: I call this technique the "In-Celebration-of-my-first-kiss-with-Ojou-Sama-Strike!"... How about it?
Setsuna: WHAAAAAT?! You were watching?!
The last chapter stated that they were both married in the same year, but specifically does not say to whom. (They are, however, wearing wedding kimonos, and Setsuna is doing a bridal carry of Konoka.
There's also the Pactio (aka, kiss) between Albireo and Nagi brought up by Konoka. Yep, even Akamatsu is willing to stick a bit of Yaoi-teasing in the series (Eishun (Konoka's father) was once seen wielding a Pactio as well). The uber-manly Jack Rakan also has a Pactio. note the manga states early on that an open-vein blood swap is another way to make a Pactio. It's more likely that one war buddy would give another a transfusion and decide to up their power at the same time, but the Ho Yay fans tend to ignore that...
Just about every interaction Negi has with any female within ten years of his age (or seven hundred years, in Eva's case) could qualify as a ship tease. This is due to Akamatsu avoiding a mistake many shows involving Unwanted Harems make and actually letting nearly every girl with an interest in Negi have a clear shot at him (Except Makie, it seems).
His "practice date" with Asuna hits this so hard that even the other characters comment on it.
Asuna is Negi's first partner, and Nodoka gives him his first non-Pactio-related kiss, but Evangeline? She gives him a ring just before he enters the Budokai tournament - and she does so explicitly in order to get him to spend less time playing with his staff.Note That is, she does so because the ring, as a focus that allows Negi to use his magic, is much less likely to interfere with hand-to-hand combat than a staff is.
Speaking of Eva, there's plenty of teasing between her and Negi. Though any attraction can easily be explained away with Negi's physical similarities with his father it's hard to deny that the resident Loli Grandma has some sort of interest in her student. From her jealously when Albireo jokingly asked Negi to be his apprentice, her statements that things would be boring if he died, and her reaction to when Satsuki proposed that Negi might have feelings for her. The girl is considered one of the likeliest candidates In-Universe for a reason.
When Negi and Ku Fei finally make a Pactio, Ku Fei teasingly mentions that because Negi was the first one to kiss her, he has to become her groom. Naturally, Negi is alarmed and freaking out because of them. Only for her to quickly say that she was just kidding. Then Chamo just has to comment what Negi's future decendant, Chao looks like ...
In one of the more surprising example, what seemed to be a Negi/Asuna moment turns out to be a Negi/Shiori one instead. Sure, the readers have already known that the current Asuna is Shiori in disguise, but how many could have guessed that the situation would be resolved with a Negi/Shiori Pactio?. Thousand Pimp indeed...
The first half of the Kyoto arc is considered one giant Negi/Nodoka ship tease. To note, she has so far been the first to confess to Negi, the first to go on a proper date with him, and the first to give him his first truly romantic kissnote He even commented in one instance that her lips felt softer than the other girls whom he had "kissed" (read: contracted a Pactio) before. (although not on the same chapter.)
Way back in the second chapter, this was quite evident on BOTH parties: Nodoka beginning to blush in front of himnote he DID save her from falling from the steps the chapter before, AND after a freak incident regarding being force-fed a beaker filled with Love Potion, and being chased by most of the girls in his class, Negi writing the words "Very Cute" in his class list, right beside her picture.
However, by far the most blatant Nodoka nod is when he went in the church's confession room. When the "Priest"note who was in all actuality Misora, one of his students who doubles as a nun asked him about who he actually likes, he starts imagining all the girls in his life. By the time he thought of Nodoka however, he blushed brighter than a tomato. He's never had that reaction to anyone else.
The Final Temptation sub-arc cranks up many of the previously mentioned ones as well as adding some new ones. Negi got to see the greatest desires of Ala Alba's crewmembers in their dreams, which include: Konoka/Setsuna(with an erotic one for Setsuna!), N(a/e)gi/Ako(Ako's), Nodoka/Negi/Yue(Nodoka's), and Natsumi/Kotarou(Natsumi's). The new ones includes Negi/Luna/Fate(Luna's), Negi/Akira(Akira's), and Chachamaru/Negi/Eva(Chachamaru's). It's unclear whether Ku Fei's are of romantic nature or not.
Judging by the fact that her blush after waking up was as deep as Setsuna's, It's probably a safe bet.
Even happens with the self-proclaimed side characters. Once Tohsakarevealed his hidden heart of gold, especially after he rejects Ako's Take Me Instead offer to give up her slave rights to him and his cronies, the manga threw in hints that he might've started developing feelings for the girl. Going as far as him Taking the Bullet meant for Ako.
In chapter 300 Anya flat out points to Asuna that everything Negi does, he does for her sake. Everything else (including saving the world) is something he does while he's at it .
Chapter 334 Eva had to remind Negi and Asuna that flirting should wait, AFTER they defeat the Lifemaker.
Also interesting to note that while Nagi protects Arika, it's Asuna who protects Negi; sort of like a flip-flop in roles. Maybe Negi+Asuna will be paired after all.
Oh god, the Yaoi Fangirls get their Fate/Negi shipping in Ch 336.
Hilariously, the ship doesn't really have any less support than a lot of the other Negi ships, and the other girls are treating it as seriously as any other. At the end of this chapter the narration reveals 'The strongest love rival?!', Evangeline refers to him as a legitimate threat a little later on, and in chapter 349 Haruna reveals that the reason she was so intent on forcing Negi to reveal his crush was because she's afraid that Negi is 'shaking off the feelings of the majority of the girls and flying off to the distant lands of masculine romance!'
It looks like Chapter 337 was a good day for Chachamaru as it looks like she's going to be Negi's new secretary, and according to Negi the work will be pretty much endless so it's practically a lifelong position. Yes, it seems like it'll be really difficult for her. It even came complete with a hilarious daydream and a touching bit at the end where Chachamaru remarks on Negi's eyes, now turned towards the future instead of after his father, as being the same eyes that granted her a soul. Note that the daydream moved into the two of them using first names, with no honorifics, and being quite casual with each other.
Chapter 93 and 94 have a Kotaro/Mei moment, after he saves her from drowning.
Chapter 338 seems to have been solely devoted to the purpose of helping Negi/Chisame fans jump. From Chisame feeling that her old daily life is missing something. To Chisame looking for Negi, and then chasing him after they meet. To Chisame quite possibly confessing to Negi with her asking Negi 'You said you always wanted me by your side, didn't you?' Followed by 'I'm going to stab you, and then I'll die too!' comment at Negi's 'Wha?' reply. Lampshaded by Chachamaru four panels later. Negi talking about his plans far ahead into the future, which he might not have told anyone else if we regard Chisame's comment on 'Looks like you wanted to talk to someone badly' as proof that she is the one he can spill his guts to without even thinking about it. And finally his seeming confession 'I've come this far thanks to you, Chisame-san' all the while inching closer to her face as he tries to 'explain' the gratitude he feels towards her. Sadly foiled by his own sneeze.
Also as a side note, the entire chapter felt like Chisame had become the embodiement, both pyshically and mentally of Naru.
In all fairness, there was a tiny bit of ship tease for Negi/Ayaka.
339 gives us (in the form of a 3x3 date) Negi/Kakizaki and Kotarou/Madoka and something completely new: Fate/Sakurako.
Even Takane "the stripper" Goodman gets teased with Negi. During the Mahorafest battle she has with Negi, Chachazero jokingly asks if Takane likes him "that way." Then Takane performs a Luminescent Blush over Negi while they're still fighting. Two hundred and forty-nine chapters later at the sports festival, she's complaining that he didn't strip her and demanding marriage.
Chapter 351 shows the class roster with Negi's scribblings of his thoughts on each of the girls. Then there's Asuna spontaneously deciding to kiss Negi.
On the same roster, an "About Valentine's" note is on both Chisame and Akira, another one is between Makie and Ku Fei, and a final one is near Nodoka. But the one near Nodoka also has the word "Done!" by it, like Negi was checking off things to ask the girls about...
Chapter 355 went for No Romantic Resolution with Negi, showing this instead. To wit, he's shown in one panel of the last chapter wearing a tuxedo, alongside The Rival wearing the same, with Asuna and Ayaka wearing dresses, but that could just as easily be a royal court function. Another panel reshuffles the people around him to show a close up of him, Nodoka, Yue, and Chisame, three of the biggest contenders in his harem (and it's mentioned that all three have frequent contact with him). Then there's Akira's panel noting that she often sees Negi at her job, not to mention Chachamaru's panel saying that her time as Negi's secretary saw her "getting wound up every day."
It's heavily hinted that most of the girls spend a lot of time with Negi whenever they can, to the point that one, Makie, outright addresses Nagi as father.
UQ Holder apparently stars Negi's grandson, and his surname is Konoe. That's right, one his parents may have been a rank bastard.
