Fanfic / SAO: The Eroge

Go To
Congratulations! You have become "The Protagonist"! Let's start raising Flags!
"The Omniverse". An infinite construct formed by infinite Multiverses, which are, at the same time, formed by infinite Universes. On it, everything can happen…

And yet, sometimes, things that are beyond all understanding and that are so horrifying they should never happen, do so.

Like in this case, something that, every time it happened, brought headaches of Cosmic proportions…[LIFE] and [DEATH] made a bet."
Opening Statement

SAO: The Eroge is a Sword Art Online Fanfic by SaintInfernalNeos.

Lots of people wish their lives could become a videogame...thing is, though, few actually bother specifying WHICH type of game. Kirigaya Kazuto is about to realize it's not as obvious as it should be when he wakes up one morning with the 'power' to raise "Flags", unlock "Routes" and gain "Affection Points". Will his Sanity survive what's about to come his way?

It was written for April Fools' Day 2018. Although not being a joke; seems to be a sort of tradition as Lusus Naturae was launched the same day the previous year.

According to SaintInfernalNeos:

"It has become, surprisingly, the most popular prologue of mine ever, and most of it in less than 24 hours of it being published."

It can be read here.

Any spoiler regarding Chapters 1-2 will be unmarked. Proceed with caution.


SAO: The Eroge provides examples of:

  • Adaptational Badass: Downplayed with Diavel, who after surviving against Illfang ends up becoming Second-in-Command of the Knights of the Blood Oath since Asuna stuck around with Kirito.
    • Argo and Kizmel permanently join up with Kirito and Asuna for longer and thus reach Clearer level.
    • Sachi who gains a Stand and joins the Front Liners as part of Kirito's harem.
    • Yuna gets a moment in Chapter 5; while captured by Laughing Coffin, tricks them into letting her use her Chant Skill to Stun most of them so she can try and get away, even putting up bit of a fight against Xaxa where she manages to score a few blows on the bastard.
  • Adaptational Dumbass: As an indirect result of Kirito's "To Protect that Smile" skill having caused 'Errors' in the system, Yui lost 90% of her knowledge and common sense and became an airhead when the Cardinal system tried to delete her.
  • Adaptational Heroism: As a result of Kirito saving Yuna's life, Nautilus (Eiji) doesn't turn as villainous as his canon self from Ordinal Scale and even befriends Klein and Fuurinkazan (Who he hated in canon).
  • Advertisement:
  • Added Alliterative Appeal: One of Argo's past relationship status names was Best Beta Buddies.
  • Argument of Contradictions: Amusingly [LIFE] and [DEATH] get into an argument of this type over which of their Gifts, living beings like more, at least when simplified into a context anyone 'normal' could understand.
  • Asshole Victim:
    • Considering Rosalia's actions towards Silica in canon, as well as here in the story where she came close to killing her, its not that hard to be not affected by her death in Chapter 5.
    • Kibaou's death at the hands of "The Fatal Scythe" in Chapter 7 didn't really affect Kirito and the others considering the former's attitude.
  • Awesome Mc Coolname: While not sounding as badass as the Black Swordsman in canon, the Nameless Knight is this as of Chapter 3.
  • Battle Harem: Considering this is SaintInfernalNeos we're talking about, Kirito is bound to have this once you get through Chapter 1.
  • Big Damn Heroes: Klein and the Fuurinkazan guild, who always show up with their 'Fuurin-mobile' to provide backup against whatever threat there is.
  • The Casanova: Played for Laughs. As Kirito's dating sim powers are an endless cause of hilarious mishaps with the heroines.
  • Cassandra Truth: While fighting Kayaba in Chapter 8, Kirito admits to the man the circumstances of his powers. Naturally Kayaba, who was already at a Villainous Breakdown prior to the fight, assumes Kirito is lying and flatly tries to kill him.
  • Continuity Nod: Quite a few for Chains of Fate.
    • We see a glimpse of [DESTINY] with his literal Cosmic Chess Game.
    • [FATE] ignores [LIFE] & [DEATH] and goes back to 'play with his Chains'.
  • Contrived Coincidence: Basically how the "To Protect that Smile" Skill works. When it activates, coincidences happen that somehow make a Heroine happy.
  • Cosmic Plaything: As usual Kirito seems to be the "The Absolute Ones" goto choice. This time [LIFE] and [DEATH] make a bet and use a Kirito to determine the winner.
  • Curb-Stomp Battle: Surprisingly, Skull Reaper, the 75th Floor Boss, who gets destroyed in a matter of minutes without causing an injury to the raid party.
  • Cut Scene: Basically what happens after choosing a Choice, to execute that choice. Complete with a Cut Scene Drop.
  • Dating Sim: What Kirito's life becomes.
  • D-Cup Distress: Downplayed with Suguha in Chapter 5, as she felt annoyed that she'll have to stop wearing a bra underneath her pajamas if her breasts kept growing.
  • Death by Adaptation:
    • Rosalia in Chapter 5 when a Boss shows up and kills her as a result of "To Protect that Smile" triggering in response to Kirito's rage when she nearly kills Silica.
    • Kibaou in Chapter 7 when "The Fatal Scythe" appears and kills him instantly when the former tried to head straight for the Admin. Console.
  • Did You Just Have Sex?: Defied Trope. Kirito took his time to school his expression before joining his party after Their First Time with Argo just to avoid this trope. A wasted effort because Argo got breakfast earlier and, well...
    At that moment, as if summoned by their words... Aincrad's most famous info broker skipped down the stairs.
    Yes, that's right. She didn't just walk down the stairs. She skipped. Argo.
  • The Dog Bites Back: With some help from Kirito, Lux manages to work up the courage to fight back against the rest of Laughing Coffin, and help the Clearers raid their base earlier than in Canon. She even manages to get a few blows in on Xaxa.
  • Dynamic Entry: The Fuurin-mobile enjoys quite a few instances of this, being used against all sort of monsters. Including Kayaba.
  • Embarrassing Nickname: In chapter 4, Kirito learns from Ducker that his constant traveling with only Asuna, Argo, and Kizmel have resulted in him gaining the moniker of 'The Ladies' Man Swordsman'. He's less than enthused by it, and part of his agreement to help stick around to train Sachi and the Black Cats alone is in hopes that spending some time away from his Party will result in the rumors and nickname dying down.
  • Exotic Extended Marriage: Kirito and his harem partake on a Dark Elf Ceremony that acted as one in Chapter 8.
  • First Kiss: With Sachi after surviving the floor trap in Chapter 4. Asuna and Argo are not happy about that, though Kizmel apparently took it in stride.
  • Fluffy the Terrible: Sachi calls her terrifyingly powerful spirit "Night Kitty".
  • Genre Savvy: Kirito knows well enough that a Declaration of Protection would do more harm than good for Sachi in the long run as it does nothing to solve her problems. Instead he chooses to encourage her to confront her issues head on, and as a result she becomes much stronger than she ever was.
  • Good People Have Good Sex: Well, what do you think happens when Kirito finishes a route? Their First Time is when Kirito and Argo both have nice, tender sex at the end of Chapter 10.
  • Head Desk: Kirito's response to Kayaba's Death Game announcement.
    • He does it again once he realizes the original of Sinon's power; specifically that she is a literal expy of Archer from Fate Stay Night (the original erogame version) in Kuro's Stripperiffic version of his costume.
  • Hero with Bad Publicity: Defied. By rebuking against Kibaou's accusations and angrily throwing the "Coat of Midnight" at Diavel, Kirito avoided the whole fiasco of his 'Beater' status in canon.
    • Played straight after Chapter 3, but downplayed. While Kibaou and most of those under his command tried to slander Kirito's deeds as the "Nameless Knight" as interference, the latter nevertheless had the respect and admiration of many players who he helped after his debut.
  • Innocent Fanservice Girl: Similar to canon, Kizmel, who has no problem undressing or being seen naked by Kirito and even acting confused when Asuna and the others get flustered over it.
  • Irony:
    • Like in canon, Sachi's insecurity of holding her friends/guild members back are apparent in her conversation with Kirito. After cutting down all the enemies that were conjured from the Floor Trap which killed them in canon and gaining more confidence in herself, it's now her guild that felt they would hold her back.
    • Klein and Eiji becoming good friends/guildmates due to being unlucky about getting a girl, in comparison to the movie where Eiji HATED Klein and the Fuurinkazan guild, blaming them for Yuuna's death, and going out of his way to beat them down until they needed to be hospitalized.
  • Lighter and Softer: Word of God has stated this will focus more on Kirito keeping his sanity intact for all the hilarity that comes with his powers than on action since the end of Chapter 1.
  • Non-Linear Character: This comes up in [LIFE] & [DEATH]'s discussion, When they try to figure out how long it's been since they have seen each other.
  • Nothing Is Scarier: Concerning certain events where Kirito enters the Dating Sim choices; the *Warning: Choosing the Wrong Choice will forever Block this Heroine's Route line always gives an ominous foreboding feeling to him that would befall on heroine who his powers are targeting.
  • Not Me This Time: Played for Laughs, as upon learning about his Embarrassing Nickname of The Ladies' Man Swordsman, Kirito instinctively looked at Argo, who quickly denied starting those rumors.
  • Papa Wolf: Kirito becomes extremely mad when Kayaba struck Yui in Chapter 8.
  • Popcultural Osmosis Failure: Argo was annoyed when her reference of Elves being the finest of Archers goes over Asuna's head. Kirito is likewise flummoxed when Philia, who is equipped with a suit of armor reminiscent of Sauron, Ring of Power included, is completely lost and doesn't recognize the reference behind her equipment and circumstances.
  • Powers That Be: [LIFE] & [DEATH] this time. For once it's not [FATE]'s Fault.
  • Reality Warper: Basically what the skill "To Protect that Smile" does, although Kirito has no control over it.
  • Sanity Slippage: Kayaba goes through this as a result of all the madness brought by Kirito's Harem Skill and goes through an outright Villainous Breakdown towards the end.
  • Screw Destiny: In-Universe. While Kirito remains unaware of it, his ability to cruise through arguments thanks to his 'Wisdom' skill and his ability to warp reality with the "To Protect that Smile" skill, allows him to avoid events that would happen in canon (Like when several universes died and others were born at the same time in a slightly, out-of-synch cycle).
  • Sentient Cosmic Force: "The Absolute Ones".
  • Shock and Awe: One of Pina's new powers after her encounter with Kirin.
  • Shout-Out:
    • A few for the Alicization Arc of Sword Art Online.
      • Kirito initially considers his 'superpower' utter crap and thinks he probably would have more luck 'cutting down a building-sized tree with an old axe'.
    • A few for the Phantom Bullet Arc of Sword Art Online
      • Kirito equipping the grey cloak he earned from a quest has got him feeling that as if he was about to embark on some 'post-apocalyptic adventure through a desert'.
    • Klein driving a boulder-shaped vehicle and appearing at unexpected times, could be a reference to how a certain sponge says that "the pioneers could drive these babies for miles". He also mentions that its bigger on the inside.
    • Kirito's thoughts of falling for Sachi with enough time is a nod to their close (If not, romantic) relationship in Volume 2 of canon, prior to the former's relationship with Asuna.
    • Sachi mowing down the Floor Trap enemies with ease and hilarity while finishing the special event, "Sachi's Bizarre Adventure".
    • The Boss that appeared during the engagement against Titan Hand was a creature from Monster Hunter: World. Silica later shows up with unique armor and skill set from the franchise.
    • Philia, discovers a ring and calls it her precious. When Kirito first meets her, she's gone so far as to wear a suit of armor similar to Sauron.
    • In order to deal with Kirito in a coma, Suguha takes up making model kits. Her personal favorite is one of the Wing Zero EW Custom. Upon ending up in SAO, her avatar takes up the appearance and weaponry of aforementioned gundam due to the memory card she used having a virtual model stored on it, which the glitched out Cardinal system merged with her ALO character data.
    • Upon entering Aincrad, Sinon appears in a bright red outfit and asks Kirito "Are you my Master?" Complete with all of the abilities and weapons that go with said outfit.
    • After being swallowed by a boss in the hollow area, Argo ends up getting a pair of blue and green energy blades belonging to a certain hierarch. Her cloak also becomes darker as if "a piece of the night was clinging to her" and remarks that she could be an actual Dark Templar
    • Strea appears decked out in clothing and weaponry straight from Bloodborne, even announcing Prey Slaughtered whenever she successfully defeats an enemy. In Chapter 13, Ludwig the Accursed also appears and is defeated, with Strea taking his Holy Sword. More bosses from the series appear later on.
    • In Chapter 13, Kizmel suddenly gains the power to manipulate elements as well as an arrow tattoo on her forehead.
    • In Chapter 14, A quest that Liz & Asuna takes rewards Asuna with the Armor of Libra.
    • Asuna's use of her Shield is clearly based after Avengers: Endgame.
    • Lizbeth happens to find an Iron Man Suit in the Hallow Area.
  • Spared by the Adaptation: In the second chapter, Coper (who had died in a failed attempt to MPK Kirito in canon) was stopped before he could enact his plan to try and trick Kirito, and was instead left Bound and Gagged inside of a cabin. Diavel also survives the First Boss Fight.
    • In Chapter 4, Sachi and the Black Cats also survived the trap that killed them in canon.
    • Chapter 5 continues the trend with Yuna, who Kirito revives with the Stone of Resurrection, thus undoing her canon death.
  • Sudden Game Interface: Of the Dating Sim variety.
  • Take a Level in Badass: Pina gets A LOT more powerful than her canon self thanks to the field boss Kirin.
  • Tempting Fate: What Kirito has realized he's done when Kayaba announces the Death Game (Well he thinks he has, [FATE] is actually preoccupied, the death game was Destined to happen anyway). For his Response see Head Desk above. For how he Temped Fate see What Could Possibly Go Wrong? below.
  • Time Stands Still: Happens whenever Kirito has to pick a Choice.
  • What Could Possibly Go Wrong?: Kirito says this (Well, as a statement) and as a Result:
    "In that instant, for some reason, several Universes died and others were born at the same time, in a slightly out-of-synch cycle, causing [FATE], on Its "Throne above Everything", to groan."


How well does it match the trope?
