WARNING: Late Arrival Spoilers abound for Mahou Sensei Negima!.UQ Holder! (aka ユーキューホルダー!, or "Eternity Holder!") is a Stealth Sequel to the popular manga series Mahou Sensei Negima! by Ken Akamatsu. Set 75 years after the end of Negima, it explores a number of ambiguous or unexplored details left at the end of that series, such as the space elevator and the adoption of magic on earth. The story began serialization in late August of 2013.The story begins in the 2080s, a decade after the existence of magic was disclosed to Earthlings, though few are able to use it well. Touta Konoe, a teenage boy living in a small village, has heard of it, but cannot cast spells. When it becomes clear that his teacher and guardian, Yukihime, is quite familiar with magic, he tries to learn it from her, but is rebuffed. He and his friends then meet another teacher who passes along a surefire way to beat Yukihime with the use of a magic bracelet and a few binding spells. However, he turns out to be a bounty hunter and goes after Yukihime — who is secretly Evangeline A.K. McDowell, an infamous vampire sorceress with a massive bounty on her head, but also an ally of Negi Springfield, the mage who saved Mundus Magicus sixty years ago when he was just a boy and paved the way for the gradual revelation of magic. After he nearly kills both her and Touta, Touta drinks the blood of Yukihime/Evangeline and becomes an immortal like her in order to gain the power to stop the assassin. Though she apologizes to Touta, he refuses to believe that she has done anything wrong, or that immortality is a curse, and together they set out into the future.UQ Holder! is one of the first round of manga to be simultaneously published on Crunchy Roll.
An Arm and a Leg: Touta's arm is cut off in the first chapter by the bounty hunter after Yukihime.
Arc Words: "Keep moving forward" and "a little bit of courage is the real magic", the Arc Words from Negima, show up here as well.
Badass Crew: UQ Holder, an organization made up of immortal humans, vampires, robots, demons, gods, and various other monsters. One of their duties is to help and protect the various friendly monsters that may be targeted by hate and/or monster hunting groups.
Another one was shown in a flashback 20 years prior to the series: one consisting of Evangeline, Negi, Fate, Albireo, Chachamaru, Mana and Zazie, all pursuing the Mage of the Beginning yet again.
Berserk Button: Hurting Yukihime or Touta's friends is a good way to end up in the hospital.
Bitch in Sheep's Clothing: Mr. Tachibana looks like a friendly, helpful guy, but he actually set up Yukihime's students to depower her so he could leap in to grab her bounty. Just so that it's clear that he's definitely a bad guy, he even makes it clear that he intends to kill all five of them as well.
Death by Origin Story: Both of Touta's parents died two years before the start of the series. They were apparently members of the Konoe family, but it's not clear what their precise relationship to Konoka (children, cousins, adopted children, etc) was.
Defeat Means Friendship: Invoked. Touta makes a bet with Kuroumaru that Kuroumaru has to do whatever Touta says if Touta wins a bout between the two. When Touta does win, his only request is Kuroumaru becomes his friend (and sign a contract formally establishing such).
Emergency Transformation: Touta is forced to drink Evangeline's blood in order to save her, himself, and his four friends in the first chapter.
Fanservice: First chapter in, and we've already got topless shots of Yukihime. Although compared to the female Fanservice in Negima and Love Hina, it's barely there. The males provide a lot of it this time around, especially Touta.
Amped up in chapter 17, wherein Karin spends the majority of the chapter fighting naked (after a full on rear end nude shot while showering).
Fate Worse than Death: When you are an immortal you can survive things you really wouldn't want to. Like being eaten by a magical beast and having to endure thirty years of being digested, or having your head locked up in a safe and dropped down the Mariana trench while alive and conscious the whole time.
Healing Factor: Vampires of Eva's level can regenerate entire limbs in the blink of an eye. Though Touta does soon lose consciousness after too much of that. Later it's revealed this healing factor has a weakness: the limb only regenerates if the original limb is destroyed. If the limb is merely cut off and doesn't get destroyed, no regeneration happens because the arm is still linked to the body and therefore not considered dead.
In the case of Kuroumaru's, his regenerates due to body modification so if anything gets injured or cut off it regenerates.
Hot Teacher: Yukihime/Evangeline's first appearance is a shot of her rear, with her students mentioning that they never get tired of seeing it.
Hotter and Sexier: Since she's no longer bound to Mahora, Evangeline's free to use her magic as she pleases and uses age changing pills to make herself look about twenty years older. It looks quite a bit different from her established "older" form, likely because she's trying to blend in rather than look like The Vamp.
Immortality: A major theme. UQ holder is an entire organization of beings with various types of immortality, drawing a clear line between not aging and actual invulnerability.
The Ageless: Jinbei stopped aging after eating the flesh of a mermaid in the 7th century, but lacks the Healing Factor of most other immortals.
Fountain of Youth / Immortality Inducer: The dark skinned man seen in chapter 6 gained immortality by using immortality granting items like Philosopher Stones, Miracle Drugs and Holy Wines.
From a Single Cell: Kuroumaru Tokisaka's immortality comes from a powerful Healing Factor, which staves off the effects of age and allows him to regenerate his body even after losing more than half of it.
Kid Hero: Though a little older than most examples of this trope, Touta is still only 14 years old.
Living Forever Is Awesome: Touta doesn't put much stock in the "living forever sucks" line of thought Evangeline espoused through the decades. Though pulls a reversal in chapter 2 (Played for Laughs), when he finds out that he's stuck as a short twelve year old for the rest of eternity, which, as it turns out, interferes with the dream he and his schoolmates promised each other.
Losing Your Head: Cutting off the head of a vampire as powerful as Evangeline or Touta doesn't actually kill them immediately. And as long as they can get their head back on their body, they're just fine.
Magitek: It's stated that Muggles who can't use magic on their own can purchase what are basically magical iPhone apps that allow the use of simple spells.
Punny Name: UQ is pronounced the same as 悠久, the Japanese word for Eternity.
Reused Character Design: Shinobu Yuuki not only has the same given name, character design and personality as Shinobu Maehara from Love Hina, they also address the protagonist as "senpai", to make it extra obvious.
R-Rated Opening: The first chapter involves Yukihime/Evangeline being rather graphically chopped to pieces by a bounty hunter. Needless to say, Akamatsu is making it clear from the start that this is not going to be a Love Hina clone.
Series Goal: Touta wants to climb to the top of the Star Scraper tower, but then he finds out all you have to do to climb it is buy a ticket. Then he decides to start organization to bring fellow immortals together, only to find one already exists. It's starting to become a Running Gag that Touta's goals are ether easy to achieve or already done.
Spin-Offspring: The main character Touta Konoe is (allegedly) the grandson of Negi Springfield.
Star Scraper: There's an impossibly tall tower in the capital where Touta believes strong mages live at the top. Yukihime/Evangeline tells him it's an orbital elevator.
Stealth Sequel: The fact that this series is a sequel to Negima! wasn't revealed until the actual release of the first chapter.
Sudden Sequel Death Syndrome: Negi is apparently dead, and perhaps so are the rest of Ala Alba, Class 3-A, and majority of the cast of Negima!. Whether this is relevant to the backstory, or is simply a byproduct of the series being set so far in the future is unknown, let alone if others actually lived through the decades through magic or life-extension technology.
In chapter 24 we know, Negi and a few more characters were at least alive 20 years ago, with their appearance and silhouette nearly unchanged from the previous series.
Talking Is a Free Action: Averted in Touta's fight against the bounty hunter. After his first attack is blocked Touta tries to throw your standard Shonen protagonist speech at the villain. Except the villain doesn't cooperate, gets behind Touta and lobs his arm off mid-sentence.
Time Skip: The series takes place in the 2080s, as near as can be figured out from some very vague numbers on gravestones, around 80 years after Negima!.
Title Drop: In the sixth chapter, we're introduced formally to UQ Holder: A group formed by an immortal Eva knew that would gather other immortals together into a family.
"We, UQ Holder, as a faction of humans who are not bound by the ways of humans, have always been protecting those who have been ejected, trampled on and forgotten by the world of humans."
Wham Episode: Chapter 24, which confirms the presence of Magia Erebea as Touta's newly-awakened power, and adds a flashback that shows Negi and a few of his endgame allies being alive 20 years prior to UQ Holder!, still fighting the Mage of the Beginning.
Who Wants to Live Forever?: According to Yukihime/Evangeline, immortality eventually becomes a curse. She appears to have outlived most of the original Negima! cast, leaving her alone once again. She's even apparently left Chachazero behind, though the opening colored pages are likely to be more symbolic than literal.
Years Too Early: Quoted word-for-word when Yukihime scolds Touta and his friends after they attack her for the first time on-panel.
