One Thousand Days
is a Maken-ki! and Negima! crossover fanfic written by Skyozoru. The story takes place before the main timeline of Negima and during the second semester of Maken Ki where the Himekagura Festival begins.
After a battle that almost destroyed the Magic World, Nagi Springfield otherwise known as the "Thousand Master" and the strongest magician in history ends up sucked into another universe. The crimson haired magician awakens in an unfamiliar world and now has to find a way to get back home but ends up dragged along with Tenbi Academy to battle against their adversary, Takeru Yamato.
According to the author, the fic is just an excuse to have Nagi who's a gamebreaker in his own world visit another world and show off just how invincible he is. However, the author also adds in different perspectives to the somewhat lacking original manga and has Nagi gain some depth that he lacked in Negima.
This fanfic provides examples of:
- The Ace: You'd think Nagi himself would qualify as this according to his reputation as the hero who saved the world and title as the strongest magician. Its subverted however in the sense that he's actually pretty dumb, lazy, and is a magic school drop out. He's still by far however the most powerful creature in existence in both his own world and the new universe he's been dropped into.
- Adaptation Expansion: The story follows Maken-Ki's timeline from Chapter 62 but gives more off screen characters and new original characters (like Isabella) more screen time and depth. Even Nagi who wasn't shown much development in Negima is given some proper development and is shown to be more than just a simple minded brute.
- Affectionate Gesture to the Head: Takeshi does this to Inaho to get her to feel better whenever she's upset, which actually works. Nagi tried it as well with her and to her surprise, his petting technique was even better than Takeshi's.
- A Magic Contract Comes with a Kiss: Just like in Negima!, Pactio's are created by having the magician kiss a suitable partner and Nagi ends up creating pactio contracts with several of the girls from Maken-Ki.
- Almighty Janitor: Nagi makes it no secret that he's a magic school dropout and can only remember less than a handful of spells to use during battle, not that he needs any more than that as there is practically nothing in either worlds that can match him in pure combat and endurance.
- Amazon Brigade:
- Every important group in the story will no doubt be filled with a bunch of female warriors who hog most of the spotlight of the story. The only exception to this is Nagi who is the protagonist.
- Otohime's new elite squad of Yamato Takeru clones fits this trope perfectly as of their debut in Chapter 14.
- Amazingly Embarrassing Parents: Undoubtedly Takeshi.
- Ascended Extra: Many of the minor and recurring characters in the original Maken Ki manga are given more spotlight, such as Kimmy Sato and Kuragasa Kai who interact with Nagi and grow from learning from him.
- Badass Boast: Nagi says a pretty epic one in Chapter 12.Nagi: "Don't tell me you plan on leaving already? Where's the fun in that? Show me your best and then let me show you why it will never be enough"
- Badass Cape: He was transported along with his trademark brown cape like how he did in Negima.
- Best Her to Bed Her: How Nagi was able to win the affections of most of his female love interests (not that any of them have a chance with him). The list includes Minori, Love Espada, Azuki, Chacha, and even Yan-Min.
- In Minori's case, it was more than just Nagi defeating her that caused the attraction; it was how Nagi treated her after the battle that sealed the deal. Minori's always been a tomboy and acted tough in front of other people because of her outrageous strength, but for the first time in her life, she was rendered completely powerless, by a man no less, and was treated like a girl instead of a boy. Nagi also calling Minori by her first name instead of how he usually calls her "Tomato Head" could also be a factor.
- Big Bad: Yamato Takeru is the main villain of not only the original manga but this story as well.
- Blood Knight: Several characters in the story are obsessed with finding worthy challenges to fight, such as Yan Min, Love Espada, and Azuki. Nagi counted for this as well at the beginning of the series, but soon quickly lost it after confirming through Takeshi that there is no one in the world who can challenge him.
- Bullying a Dragon: Minori, Takeshi, and Himegami all had no idea who they were messing with when they all at some point tried to pick a fight with Nagi. I'm sure you can guess how each encounter with them went.
- Curb-Stomp Battle: Every battle with Nagi eventually ends up as this, such as his brief sparring session with Takeshi and his full on duel with Minori; both of which ended up with Nagi not even using a fraction of his full power.
- The Net Ball event battle between Team Tenbi and Team Yamato Takeru in Chapter 10. Espada and the other third years make short work of Takeru, Azuki, and Aki without breaking much of a sweat and show why they were called the Four Pillars.
- Chick Magnet: Just like in his previous world, it doesn't take long for a swarm of girls to fall for Nagi In fact, one of the main vocal points of the series is finding out how many women Nagi can woo before he finds a way back home.
- Crossover: One between Maken-ki! and Negima!.
- Double Standard: Abuse, Female on Male: Played straight with Himegami, Haruko, Azuki, Minori, and the other girls who discipline Takeru and Usui whenever they're acting like perverts. Completely averted in regards to Nagi however, who can get away with saying and doing practically anything he wants because he's smart enough to realize that no one can stop him.
- Didn't See That Coming: In chapter 12, Akaya never would have predicted that Espada and the other third year girls would show up to try and kidnap Nagi just when they were planning on investigating him.
- Yamato Takeru's early awakening pretty much took the entire Tenbi squad by surprise in Chapter 14 as no one could have predicted he would wake up so soon.
- Fiery Red Head: Minori and Azuki certainly count but Nagi himself is a subversion in the sense that while he was definitely this trope when he was younger, he's matured and acts reasonably calm and composed most of the time...though he's still a simple minded war monger.
- The Gadfly: Oh boy, Nagi without question embodies this trope. Almost everything that comes out of his mouth is in some way, shape, or form an attempt to get a reaction out of those around him and it works. Every. Time.
- Happily Married: Before coming to the world of Maken Ki, Nagi was trohappily married to Arika and even fostered a child with her before he was sucked into a black hole and brought to another world. Of course, Nagi still loves her and constantly thinks about her well being.
- Happiness in Slavery: Espada has now technically becomes Nagi's slave after forming a contract with him in Chapter 13 (or rather his servant) and has shown to be quite welcoming of the idea if her reaction to Nagi "punishing" her is anything to go off of.
- Heel–Face Turn: During her debut, Espada was originally an antagonist under Otohime's brainwashing but after being captured by Nagi and being saved by him (thanks to the pactio contract), Espada has since joined Tenbi Academy once again and serves as one of Nagi's partners.
- Heroic Sacrifice: After the battle between Nagi and Zeto, a black hole appeared right in between them that was going to suck them both in but Nagi, being the man that he is, used the last of his strength to throw Zeto out of the way and let himself be the only one captured.
- Instant Fan Club: Not even a day after Nagi arrives at the school with Takeshi, almost all of the girls in the school end up creating a fan club for him.
- It Amused Me: Almost all of Nagi's actions stem from his desire to get a reaction out of people and entertain himself.
- Loveable Sex Maniac: Love. Freaking. Espada. Apparently, one of her hobbies is looking for new students to "play with" and she finds pleasure in just thinking about having her way with her enemies after she's beaten them thoroughly.
- Love at First Sight: Isabella Garret fell for Nagi hard after witnessing him half naked in Takeshi's Dojo. Considering this is Nagi who we're talking about, it doesn't come as much as a surprise.
- And now, chapter 11 gives us Otohime who has suffered the same fate as Isabella but to a more extreme degree as she not only wants Nagi to be her lover, she wants him to be her slave.
- Pretty Boy: Nagi's been able to charm almost every girl he's come into contact with.
- Rescue Romance: Seems to be the case with how Nagi got Minori to fall for him as he pulled her out of the way before his attack could vaporise her.
- Smug Super: Nagi knows that he's stupidly powerful which is why he acts arrogant towards practically everyone.
- Story-Breaker Power: Quite a few Maken that exist in canon are quite ridiculously overpowered (such as Celia's Inverse and Espada's Furuno) but Nagi himself qualifies as his magical powers are so outrageously strong that even Minori, who's considered among the strongest in that universe, is absolutely no match for him.... even while he's holding back.
- Trapped in Another World: Essentially the entire plot: Nagi's trapped and tries to find a way back home. Doesn't stop him from getting involved in Maken Ki's plot however and teaching the students at Tenbi Academy a thing or two about saving the world.
- Troll: It seems one of Nagi's favorite past times is trolling the hell out of the girls, the most prominent case being Himegami.
- Tsundere: Himegami certainly seems to be a Type A for Nagi, switching over to Type B more frequently as the story goes on. Minori also counts as well due to her growing feelings for Nagi that she refuses to admit, placing her in Type A territory. Isabella is always a Type B whenever she's speaking with Nagi.
- Vitriolic Best Buds: Nagi and Takeshi become quite the pair between Chapters 2-4 and visit Tenbi Academy. Takeshi himself is even surprised at how comfortable he finds Nagi's company to be.
- World's Best Warrior / World's Strongest Man: Nagi, by far. There is no one in the Maken Ki universe who comes close to rivaling his full strength and the only way he could be defeated is through the use of an overpowered Maken.
- Apparently that won't even work anymore as they can't even harm him because Nagi soon finds out that the abilities of Maken can be guarded against if he uses his magic to coat his body.
- You Have Outlived Your Usefulness: After Espada is defeated and captured by Nagi, Otohime activates the collar around her neck that is filled with poison to silence her from leaking any of Kamigari's secrets.
