Light Novel / A Wild Last Boss Appeared

Go To
The Supreme Ruler is Back!
It was in the year 2800 of the Midgard calendar. Back then, there was a Overlord who once reigned supreme and had reached the very brink of subduing the world. Her name was Ruphas Mafahl, a great woman dreaded as the Black-Winged Overlord. She was too strong, too fast, and too beautiful. However, she was defeated by Heroes who opposed her ferocity, and her ambition was brought to an end.

Or so went the story of our protagonist’s in-game character, whose body he now possesses for some reason in a world 200 years after Ruphas' downfall. Follow our protagonist as he becomes unnecessarily feared by his surroundings and unnecessarily worshiped by his former subordinates as he―or now she―cheerfully travels around this fantasy world.

A Wild Last Boss Appeared! (野生のラスボスが現れた!Yasei no Rasu Bosu ga Arawareta!) is a Light Novel and web novel series currently with eight volumes printed.

Needs Wiki Magic Love

  • The Ace: Ruphas. Taking aside the fact that she's a level 1000 player in a world where the highest level NPC is level 120 at most, she was once the top-ranked player of Exgate Online which the new world is based on. In fact, she was so much of an ace that she eventually became the first player to actually conquer the entire map of Midgard. A feat that eventually resulted in her being nicknamed by other players as "A Wild Last Boss" and also becoming semi-canonical within the game's lore itself.

  • All the Other Reindeer: Ruphas' memories show she was discriminated by the other Flugels for being born with black wings. Hence why when she took over the world she treated all other races as equal under her rule.
  • Ambiguous Situation: It's not quite clear if Ruphas' world is an entirely distinct one in its own right that influenced the protagonist and the game or if the background details of the game and taking things to their logical conclusions caused it to become more complex than the protagonist thinks it should be. Basically, what really happened with, say, Aries' recruitment? Did Ruphas Mafahl find a legendary but weak sheep monster and teach it to stand up for itself before adopting it or did a random Japanese teenager find a rare spawn monster that just sat around looking dopey until he started taming it, causing it to ineffectually attack him once before submitting?

  • Badass Crew: Ruphas followers are quickly becoming this with every Heavenly Star that joins them.
  • Battle Butler: Algokeros' (the Capricorn) human form looks like a butler, and he's just as deadly as the other Heavenly Stars.
  • The Beastmaster: Ruphas has the Beast Taming skill, and that allowed her to tame monsters into her subordinates. Though rare and unique boss monsters have low chance of being tamed, Ruphas was lucky enough to have tamed enough of those to become her generals, the Supreme Ruler's Twelve Heavenly Stars.
  • Black Eyes of Crazy: Demons have black sclerae, and they serve as antagonists.
  • Boobs of Steel: Ruphas has a well endowed chest, and being a physical fighter she also packs the biggest punch in the story with the possible exception of the demon king Orm.
  • Bring My Brown Pants: After a lengthy chase which already drives him into Villainous Breakdown, Jupiter finally pees himself when Libra is about to blast him into oblivion with her infamous Brachium unless he surrendered.
  • Canon Immigrant: In-Universe. The MMO of Exgate online had a function that allowed players to basically write their own stories in-game. Ruphas' popularity made the game executives turn her into a semi-canonical character, with her rule of the world and later defeat be included in the in-game story.
  • The Corruptible: The 12 Heavenly Stars took the defeat of their masters 200 years ago extremely bad. Among them, Aries and Algokeros were eventually convinced and manipulated by the demonic generals Seven Luminaries to destroy the remaining living Heroes, forcing the recently awakened Ruphas to set them straight.
  • Curb-Stomp Battle: Because of her high level of 1000, Ruphas can basically plow through almost anything the world throws at her.
    • The confrontation with the orcs is basically just one swift execution in favor of Ruphas.
    • Mars might be strong by the standards of the world, but when against Ruphas, he's finished in a single punch.
  • Curse: Apparently the demon king Orm aflicted this to the Seven Heroes, cutting their levels, skills and stats in half. The curse also affected them physically, with Megrez being confined to a wheelchair and Merak losing one of his wings.
  • Defeat Means Friendship: After being ousted and realizing she can't defeat Ruphas, Venus/Dina genuinely joins Ruphas as her advisor
  • The Dreaded: Ruphas. Her subordinates aside, everyone - including humans, elves, orcs, demons and angels fear her so much to the point her appearance is still easily recognized even 200 years after her defeat. Back during the times of her rule, even the Demon King Efreet wasn't all too thrilled with the prospect of fighting her and the Heroes, and bid his time until after the Heroes betrayed her and broke apart.
  • Dude Looks Like a Lady: Thanks to the suggestion of Ruphas' teammate Mizaal, Aries' human form looks like a beautiful girl despite being classified as a male.
  • Dwindling Party: Of the original Seven Heroes that defeated Ruphas, only three remain alive after 200 years.
  • Elemental Rock–Paper–Scissors: Everyone has an associated element, which has strengths and weaknesses among the other elements. Water > Fire > Metal > Wind is an explicit example of the powers, but as this resembles the classic Chinese elements it's also presumably more complex with additions like wind strengthening fire.
  • Fantastic Racism
    • Flugels (who are believed to be descended from angels) tend to look down on those with multicolored wings, seeing pure white wings as superior. Ruphas (who has black wings) abolished that caste system when she took over the world.
    • Orcs and beast people are actually the same thing, or rather orcs are pig type beast people. This means they should qualify as humanoids just like humans and elves. However, their unique reproductive needs keep them from being accepted by the humanoid races and are instead treated as monsters.
  • Good Wings, Evil Wings: Ruphas may have pitch-black wings that are scorned by the other Flugels, but she's rather kind and caring towards her followers. In-Universe his creator was fully aware of this trope, as he thought the black wings which goes against the society's norm was cool when designing Ruphas.
  • Graceful Loser: Both Ruphas and his creator (more justified in his case) don't have any ill will for the heroes for defeating her, and both are content with exploring the world in relative peace.
  • Greater-Scope Villain: Demon King Ifreet believes The Goddess who created Midgard is playing a Cosmic Chess Game with him and Ruphas.
  • Happily Adopted: The flugel Virgo who was adopted by the human Parthenos.
  • In the Hood: Ruphas wears one at the beginning of the story to hide her wings and face from those that might remember her. Megrez later gives her a concealing item that hides her wings and outfit.
  • Implacable Woman: Once Libra has you in her sight, there is nowhere you can hide from, as Jupiter found out.
  • Living Prop: What Dina basically was in the game, and that's how Ruphas and the Stars remember her. Which was very convenient for Venus to impersonate as.
  • Man, I Feel Like a Woman: Subverted. When Ruphas' creator finds himself in her body, he feels the temptation of testing her... equipment, he chooses not to since she's his beloved creation.
  • Megaton Punch: Ruphas doesn't wield weapons and this is how she usually defeats her opponents. Or destroys a giant meteor conjured by Venus.
  • More Than Mind Control: It's indicated that the goddess is the one who manipulated Ruphas' teammates and general public perception into turning against her. Rather than controlling them outright, however, she manipulated their feelings of inferiority, rivalry and fear. Afterwards, people seemed to snap out of it and wonder what the hell they were doing at such an important time.
  • Narm: In-Universe. Ruphas' creator thought naming her subordinates' the Twelve Heavenly Stars as a bit cheesy and something of an Old Shame.
  • Nice Job Breaking It, Hero!: Or heroes in this case. 200 years after Ruphas' defeat and the world is in a worse state than during Ruphas' rule, making the surviving heroes regret having done the deed in the first place.
  • No Name Given: Ruphas' creator name and face aren't known.
  • Our Ghosts Are Different: After dying as a human, Parthenos of the Twelve Heavenly Stars lingered within Vanaheimr and even recreated her appearance when she was young.
  • Persecution Flip: Ruphas, despite being gorgeous by human standards, is considered horribly ugly by Flugels because they judge beauty by how close wings are to being pure white. When she was growing up the other children constantly threw rocks at her and her father would beat her if she fought back.
  • Pint-Sized Powerhouse: Aries may have the human form the size of a little girl, but he's still a level 800 with strength that surpasses anything else in the world barring the other Heavenly Stars, his master Ruphas, the Demon King Orm and another player, Dina.
  • Reality Ensues: In "Exgate Online", level 1000 players like Ruphas were a pretty common sight. However, once she arrives in the world of Midgard, she quickly finds out that the currently strongest warrior of the land is at level 120. Demanding why it's so low, Dina points out that it was her generation that was full of abnormalities. Soon afterwards Ruphas is able to piece together that thanks to the fact that it was just a game, people like herself could level up without worry and with ease even if they die. To the people of Midgard however, Final Death is in full effect.
  • Really 700 Years Old: Elves and Flugels are known to live for centuries and barely age. Ruphas herself is lore-wise 400 years old, but looks like a woman in her twenties.
  • The Reveal: Not only Dina is actually Venus of the Seven Luminaries, she's also a player and a level 1000 just like her, albeit not as well-developed as Ruphas. Specifically she was a test player checking out new features to be implemented into a new patch and then suddenly found herself in the real world of the game. As she's a half-elf, she has a long lifespan and spent the last 200 years looking to defeat the Demon Lord, even infiltrating the demons forces for a chance.
  • Robot Maid: Libra is a golem in the shape of a maid.
  • Scissors Cuts Rock: Normally a water elemental like Megrez' Leviathan would have an advantage over a fire elemental like Aries, but the difference in level is so much Aries can almost evaporate Leviathan out of existence.
  • Storm of Blades: While she lacks hand-held weapons, Ruphas can summon one of these as long-ranged attacks.
  • Summon Everyman Hero: This is what the Kingdom was trying to do, only they ended up releasing Ruphas instead. They succeed at the end of the second volume.
  • Too Awesome to Use: Played for laughs. Elixirs are a legendary medicine and one Sei recognizes from games as extremely rare but something you never end up using because you can get by without it and don't want to waste it. That's fine. The joke is that the original Ruphas did the exact same thing. As in, really stockpiled legendary treasure medicines just like she was playing a video game.
  • Undying Loyalty: Ruphas' followers have this even two centuries after her sealing.
  • Vindicated by History: In-Universe. According to Dina, Ruphas' rule is more fondly remembered 200 years after her defeat, since the world was united under a single ruler.
  • Winged Humanoid: Flugels are descendants of true angels, which gives them a rather inflated view of themselves.
  • World's Strongest Woman: Again, Ruphas. She's so strong that, in addition to conquering the entire world, even the Demon King himself (the actual final boss of Exgate Online) feared her so much that he made a point to avoid conflict when possible. When they finally do meet during the story, he notes that Ruphas as she is right now is actually weaker compared to how she was before she was sealed away.
  • You Gotta Have Blue Hair: Aries' human form has white hair, while Dina's hair is blue.
  • You Have Outlived Your Usefulness: Venus kills Mars once his plan of using Aries fails, and to ensure he doesn't exposes her.
