[[caption-width-right:350:Talk about [[IncrediblyLamePun double vision]].]]

A [[{{Shojo}} shoujo]] manga based on the [[OlderThanFeudalism age-old tale]] of [[ReincarnationRomance reincarnated lovers]]... with a twist.

Keidai Saeki, average Japanese high school student, remembers living an entirely different life as Sirix, a gladiator in ancient Pompeii; this means he has a hard time existing in the ''present'', especially when no-one else seems to have memories of their own. Keidai exists in two worlds, one of which is long dead: His little sister in his past life is married to his former rival and they're now his parents, his male best friend is a cute girl with a crush on him, and his beloved wife Serena has been reborn as the short-tempered boy next door who's crushing on said best friend! And of course, Keidai is literally incapable of seeing them as anything ''but'' their past-life selves.

Life for Keidai is essentially a twenty-four-hour {{Mind Screw}}.

''NG Life'' is a nine-volume romantic dramedy by Mizuho Kusanagi, the mangaka responsible for ''Mugen Spiral'', ''Manga/YonaOfTheDawn'', and ''Manga/GameXRush''. Licensed for North America and published in English by Creator/{{TOKYOPOP}}, all nine volumes have been released as of July 8 2011.

!!This manga provides examples of:

* AllMenArePerverts: Serizawa's dad certainly thinks so; it becomes HypocriticalHumor when we discover that he draws ecchi manga as part of his job, and Keidai earns his respect by proving that 'girls in wet clothes are sexier than naked girls!'
* AloofBigBrother: Though they're not related - ''yet'' - Raoul acts this way towards Sirix, particularly during the Pompeii arc.
* AlwaysWithYou: Loleus' dying words to Sirix.
* BodyguardBetrayal: Delos turned out to be targeting Aglaia, whom he nonetheless looks out for, due to his working for a rival house.
* ChivalrousPervert: Shinogu. He's happy to have a harem of [[{{Joshikousei}} high school girls]], but he doesn't take advantage of them, as some clearly want him to. Almost definitely a result of a) still remembering having been a woman and b) because he hated, and still hates, men like that.
* CrashIntoHello: This is how Loleus and Sirix meet.
* DeathEqualsRedemption: Delos forgoes escaping and dies in Pompeii, having remained behind to wipe out his family in revenge for their plot against Aglaia's house.
* DeclarationOfProtection: Loleus had decided that he'd live for three people: Sirix, Serena, and Lady Aglaia.
* DefrostingIceQueen: Both Smyrna/Shinogu and Reina begin to defrost after their interactions with Sirix/Keidai, and [[spoiler: it's implied that both have [[UnrequitedLoveTropes one-sided feelings for him]], not that they'd ever admit it. ''Especially not Smyrna/Shinogu.'']]
* DespairEventHorizon: Keidai, unable to reconcile his feelings for Serizawa with his disappearing memories of Pompeii; Loleus, lying beaten and alone by the roadside.
* TheDeterminator: When motivated by those he loves, nothing can stand in Sirix/Keidai's way.
* DoesNotLikeMen: Smyrna big time, even when she gets reincarnated ''as'' a guy. [[spoiler: The one man that she... ''perhaps'' didn't hate quite as much as the others happened to be Sirix.]]
* DreamingOfTimesGoneBy: A standard part of Keidai's life; he even ''day''dreams of times gone by.
* FirstGirlWins: In the long run, though [[spoiler: technically when they first met Mii was Loleus, not a girl. Then again, aside from his parents, Mii was the first of Keidai's reincarnated friends/acquaintances to meet him in their new life, so it counts either way]].
* ForegoneConclusion: We all know [[ChekhovsVolcano what happened to Pompeii]].
* FriendlessBackground: Though he was befriended by Serena and appreciated her kindness, Loleus - as a [[DarkAndTroubledPast slave]] - felt as if no-one would care if he died, until he met Sirix.
* GladiatorGames: Everyone's past lives practically revolved around them: They were either gladiators themselves, worked as part of the games, or were part of families involved with the games.
* GenkiGirl: Serizawa.
* GoOutWithASmile: [[spoiler: Aglaia]] dies like this.
* GothicLolita: Reina dresses this way and affects a sarcastic demeanor more mature than her age.
* HeroicSacrifice: [[spoiler: Aglaia]] pushes Sirix, who's carrying a wounded Loleus, to safety just before the tunnel collapses.
* IWantMyBelovedToBeHappy: Loleus had a double dose of this, as he carried feelings for both Sirix and Serena. This was basically why Loleus encouraged Sirix to pursue a relationship with Serena in the first place. Later, he says it almost word-for-word, no less.
-->'''Loleus:''' "Sirix.... I want you to be happy. I want you and Serena... to be happy"
* InvoluntaryBattleToTheDeath: When Sirix and Loleus face off in the arena. It gets averted, though.
* {{Irony}}: Serena was reborn a boy because [[spoiler: on her last day, she wished that she were a man, so she could accompany Sirix through crumbling Pompeii. At the time, Sirix smilingly replied that if that were to happen it would cause him problems; in their next life Serena ''is'' reborn as a guy, which does in fact cause Keidai problems.]]
** Smyrna hated men but was reborn as a man. Her reincarnation Shinogu turns out to actually be glad about this as it means he can skillfully woo pretty girls, but he still continues to hate all other men except for himself and Yuuma. [[spoiler:[[{{Tsundere}} (And secretly, Keidai.)]]]]
* JumpingTheGenderBarrier: Hey, guess what? Your best guy friend who'd do anything for you is now a cute girl with a crush on you! Too bad you're still hung up on your past-life wife, who's jumped the gender barrier ''in reverse''.
* LoveConfession: [[spoiler: Once he realizes his feelings for Serizawa, Keidai has to do this about three or four times before she finally believes him.]]
* LoveTriangle: Complicated in both past and present!
** In the past, Sirix and Serena loved each other, and Loleus was Sirix's best friend who harbored feelings for Sirix deeper than mere friendship, but Loleus also was friends with and loved Serena (though he completely disregarded the idea of pursuing her because he was a slave), and it's implied that it wasn't entirely unrequited either; In fact it was because of Loleus's feelings for both of them that caused him to pair them up!
** In the present, Keidai's stubbornly hung up on his memories of Serena, but the fact she's been reincarnated into the very male body of Yuuma is a serious barrier for him. Serizawa on the other hand, has feelings for Keidai, but he's oblivious to both them ''and'' the fact that he's coming to have feelings for her too, because he can't stop seeing her as her past self, Loleus. And in the meantime, Yuuma develops a crush on Serizawa.
* MagneticHero: Sirix. Nearly everyone at least respected him, and Keidai has a similar effect on people, despite being [[{{Buttmonkey}} somewhat less impressive]] on the surface.
* MeaningfulEcho: "We'll meet again." You know, because... {{Reincarnation}}.
** After meeting Loleus, Sirix pretends to have 'forgotten' why Loleus treasures that scrap of cloth; in a similar fashion, Keidai pretends to have 'missed' Serizawa's reply to his final confession.
** The current lives of a number of characters turn out to be "meaningful echos" to wishes made by their past lives.
*** Serena was [[spoiler: reborn a boy because she felt that if she were a man, she would've been strong enough to remain by Sirix's side when he went off to rescue Aglaia in the midst of Vesuvius's eruption]]
*** Loleus was [[spoiler: reborn as the girl who would become Keidai's best friend, confidant, and ultimately love interest, because as Loleus was dying he told a grieving Sirix that even if he died, he'd be a "light who'd fly to his side" no matter where Sirix was.]]
*** Later we find out Reina is [[spoiler: the reincarnation of Tina, a former slave girl who had a disfigured face and after being abandoned, was eventually rescued and cared for by Serena. She was reborn looking identical to Serena because she envied, admired, and wanted to be like her.]]
* MeaningfulName: The series itself: NG Life = [Keidai's] No Good Life. After everything's sorted out, an epilogue chapter changes it to Nice Going Life.
* MementoMacGuffin: Loleus treasures the strip of cloth Sirix used to bind his hand when they first met; his second-most treasured item is a gold headband Aglaia gave him after she saved him from the gladiator games.
** Perhaps more accurately, Smyrna's ring in the past-life side-story.
* MistakenForGay: Keidai's goodbye message during Shinogu's stint as a substitute teacher apparently sounds like a LoveConfession.
* TheNotLoveInterest: Loleus to Sirix. Loleus was Sirix and Serena's matchmaker, but Loleus and Sirix were mighty close friends who went through a lot together and cared deeply for one another. While confronting Delos, Loleus basically admits that Sirix is his most important person; Now in their reincarnated forms, Serizawa still puts Keidai before even her own feelings. [[spoiler: Subverted in that their bond in their past life was what paved the way for Loleus to be reincarnated as Serizawa in the first place, and ultimately ''become'' Keidai's love-interest.]]
* OneOfTheBoys: How Keidai treats Serizawa for most of their friendship, mostly because he can't stop seeing her as his male best friend.
* PairTheSpares: While this may be one reason behind the popularity of the Yuuma x Reina [[{{Shipping}} ship]], many fans simply seem to really like the way [[{{Tsundere}} they]] interact with each other.
* PleaseDontLeaveMe: Sirix says it almost word-for-word as he [[DiedInYourArmsTonight cradles a dying Loleus]].
* RapeAsDrama: Almost happens to Smyrna in a side-story; leads to [[spoiler: a one-sided (and ''extremely'' well-hidden) RescueRomance on her part when Sirix interferes.]]
* {{Reincarnation}}: The centerpiece of the story, of course!
** ReincarnationRomance: For Aglaia/Shuna and Delos/Souichi as well as Raoul, Aria, and their incarnations as Keidai's parents. Also for Keidai, eventually, though not the way he thought it would be.
* ShoutOut: Keidai and Yuuma pose for manga-artists working on 'a romance between an assassin and a female bodyguard,' a reference to the mangaka's previous series ''Manga/GameXRush'', in which the male bodyguard was originally meant to be female.
* SurvivorGuilt: A large chunk of Keidai's unwillingness to move on is guilt; he blames himself for failing to save anyone and believes that his penance is to remember everything that happened, despite the fact that no-one could have predicted or prevented Vesuvius' explosion and that Sirix just died last.
* TakeAThirdOption: When Raoul tells him that he can "only protect one thing" - go to Serena or rescue Loleus and Aglaia - Sirix refuses to choose. [[FromBadToWorse It... doesn't go so well]] and results in a form of crosslife HeroicBSOD.
* ThoseTwoGuys: The group of slackers that Keidai teams up with for volleyball become recurring extras. Lampshaded often with asides next to them indicating who they are (i.e. "I'm ______!").
* {{Tsundere}}: Yuuma and Shinogu are ''extreme'' Type A's towards Keidai... particularly Shinogu, who exhibited identical behavior towards Sirix as Lady Smyrna. It's all but stated that bullying him with the DoesNotLikeMen persona is how Smyrna/Shinogu covers for actually caring about Sirix/Keidai.
