Vanessa Piña has been writing as a journalist for over two years. As a senior writer, she focuses on timely coverage of the latest anime releases and popular comic franchises.

While fans await the confirmed date for the new Solo Leveling movie, there's no better way to stay entertained in the meantime than with a new anime, and one of the top contenders comes from the isekai genre. Solo Leveling feels somewhat "isekai-adjacent," not only due to battles against monsters invading the world but also because of an air of fantasy intrigue suggesting there's far more than meets the eye. For viewers looking for something with a similar vibe yet a style all its own, a recent isekai hit has just returned to Crunchyroll.

Anime fans naturally gravitate toward protagonists with overwhelming power, a trait Solo Leveling and A Wild Last Boss Appeared! have in spades. Although the latter may seem far more lighthearted than Solo Leveling at first glance, the two stories share similarities that make A Wild Last Boss Appeared! an excellent follow-up series. With both series centering on an ordinary person who ends up commanding powerful subordinates and featuring numerous mysteries, spectacular battles, and even some of the same production staff, Lufas Maphaahl's journey offers exactly the kind of experience fans of Sung Jinwoo might be looking for.

While Solo Leveling is busy pushing an emerging power fantasy genre to grow its numbers, A Wild Last Boss Appeared! had plenty of competition in the already-saturated isekai anime market on Crunchyroll. Featuring the #1 player of the in-series fictional game Exgate Online as he's then trapped in the body of its avatar, this anime sat initially in Overlord's shadow.

The Japanese term “isekai” (異世界) is now the catch-all label for stories about ordinary people transported, summoned or reincarnated into a fantasy realm — from Sword Art Online to Konosuba to Mushoku Tensei. What does the word literally translate to in English?

AHidden World BDifferent World CFloating World DLower World

✓ Correct! “Different world” or “another world.” The word breaks into i (different) + sekai (world). The genre traces back as far as 1990s OVAs (Vision of Escaflowne, Fushigi Yuugi, Inuyasha) but exploded in the 2010s thanks to Sword Art Online (2009 LN, 2012 anime), Re:Zero, KonoSuba, Overlord and the “Narou” web-novel ecosystem of Shōsetsuka ni Narō.

✗ Wrong. The answer is “Different World.” Isekai breaks down literally to “i” (different) + “sekai” (world). It’s now used as a publishing-industry shorthand for the entire genre of transported/reincarnated/summoned-hero stories that boomed across the 2010s.

Re:Zero — Starting Life in Another World’s protagonist Subaru Natsuki is a hikikomori who’s pulled into a fantasy kingdom and given a single, brutal supernatural ability: when he dies, time rewinds to a fixed checkpoint and he relives the same stretch of days, retaining his memories. Name this signature ability.

AReset BRebound CReturn by Death DLoop Trance

✓ Correct! Return by Death. Subaru’s ability is treated by Tappei Nagatsuki’s novels as a curse rather than a power — the Witch of Envy locks his memory of it (he physically cannot tell anyone he can rewind), and every “reset” means he genuinely dies. Re:Zero is widely credited with redefining the modern isekai psychological lane and remains one of the genre’s most acclaimed entries.

✗ Wrong. The answer is Return by Death. None of the other names are official. Tappei Nagatsuki’s web-novel-turned-LN coined “Return by Death” specifically and made the death-and-rewind a thematic engine: every reset means a real death and accumulating trauma.

In KonoSuba: God’s Blessing on This Wonderful World!, NEET protagonist Kazuma Sato dies and is offered a wish by an obnoxious goddess. He chooses, out of pure spite, to take her with him to the fantasy world. She becomes the party’s perpetually-dunked-on, Drain-Touch-fearing water-and-resurrection priestess. Name her.

AMegumin BAqua CDarkness DWiz

✓ Correct! Aqua. The goddess of water, useless and proud of it. Kazuma’s entire character arc is being saddled with three of the most dysfunctional party members in any RPG — Aqua (the goddess), Megumin (the explosion-only Crimson Demon mage) and Darkness (the masochistic crusader who can’t hit anything). Aqua’s mortal terror of Drain Touch and undead is one of the show’s longest-running gags.

✗ Wrong. The answer is Aqua. Megumin is the explosion-magic mage. Darkness is the masochistic crusader. Wiz is the lich shopkeeper. The goddess Kazuma drags into the fantasy world — and the source of about 90% of the party’s problems — is Aqua.

In That Time I Got Reincarnated as a Slime, Mikami Satoru is stabbed in modern Tokyo and reincarnates in a fantasy world as a low-tier blue slime monster — only to discover his new body has the absurd Predator Skill that lets him absorb anything he eats. He soon names himself after a great storm dragon he befriends in a cave. What name does he take?

ALugh Veleno BRimuru Tempest CHajime Nagumo DNaofumi Iwatani

✓ Correct! Rimuru Tempest — surname taken from Veldora Tempest, the Storm Dragon Rimuru befriends and absorbs in his first cave. By the time the series gets going, Rimuru is the founder and ruler of the monster nation Tempest, a Demon Lord, and the most powerful single character in his world. Fuse’s web novel started in 2013, Kawakami’s manga adaptation is over 25 volumes deep, and the 8-bit Studio anime is still ongoing.

✗ Wrong. The answer is Rimuru Tempest. Lugh Veleno is the protagonist of The World’s Finest Assassin Gets Reincarnated. Hajime Nagumo is the lead of Arifureta. Naofumi Iwatani is the Shield Hero. The slime who eats Veldora and names himself Tempest is Rimuru.

In Overlord (2015–), the Yggdrasil MMORPG’s servers shut down on the player Momonga, but instead of logging him out, he and his Great Tomb of Nazarick are pulled into a parallel world. He renames himself after his old guild — the same name that gives the show its menacing brand-villain register. What does he rename himself?

AAlbedo Cocytus BAinz Ooal Gown CDemiurge Solomon DTouch Me

✓ Correct! Ainz Ooal Gown. Originally the name of Momonga’s 41-member Yggdrasil guild — the “Nine’s Own Goal” in original Japanese — he reclaims it as his personal alias to honour his absent guildmates. Maruyama’s LNs and Madhouse’s anime treat the protagonist as a slow-burn villain: a skeletal Eldritch Lord trying to figure out what he’s become while his floor guardians worship him as a god.

✗ Wrong. The answer is Ainz Ooal Gown. Albedo and Cocytus are NPC floor guardians of Nazarick. Demiurge is another floor guardian. Touch Me was a famous member of the original guild but isn’t Momonga’s alias. The protagonist takes the guild’s own name, Ainz Ooal Gown.

Sword Art Online’s first-arc death game traps Kirito and 10,000 players inside a 100-floor floating-castle MMO — if you die in the game, you die in real life. Each floor is a distinct biome and boss fight, and the only way out is to clear all 100. What is this castle/MMO called?

AAincrad BAlfheim CUnderworld DGun Gale

✓ Correct! Aincrad — the floating fortress designed by lead-developer-villain Akihiko Kayaba. Reki Kawahara’s LN began as a 2002 web novel and was adapted by A-1 Pictures in 2012, kicking off the modern isekai boom. The series moved through other servers/worlds across its sequels (Alfheim Online, Gun Gale Online, Project Alicization’s Underworld) but Aincrad remains the foundational setting and the brand image of the franchise.

✗ Wrong. The answer is Aincrad. Alfheim is the fairy-themed VRMMO of Season 1’s back half. Gun Gale Online is the FPS arc. The Underworld is the simulated world of the Alicization arc. The first-season death game is the floating fortress Aincrad.

Mushoku Tensei: Jobless Reincarnation (2021–) is widely cited as the foundational modern isekai web novel — published online from 2012, it’s often credited with defining the genre’s template. Its protagonist is a 34-year-old NEET reincarnated as a baby in a fantasy world, retaining his adult mind. What’s his new-life name?

ACid Kagenou BRudeus Greyrat CArs Lalatoya DSubaru Natsuki

✓ Correct! Rudeus Greyrat — born to swordsman father Paul and maid mother Zenith in the Buena Village in the Asura Kingdom. Rifujin na Magonote’s web novel ran from 2012–15 on Shōsetsuka ni Narō and is widely credited as the prototype for the modern reincarnation-isekai template. Studio Bind’s anime adaptation (2021–) is one of the genre’s most lavishly produced.

✗ Wrong. The answer is Rudeus Greyrat. Cid Kagenou is the lead of The Eminence in Shadow. Ars Lalatoya is Rudeus’s son later in the series, not Rudeus himself. Subaru Natsuki is the protagonist of Re:Zero. Rudeus is the reborn-as-a-baby protagonist of Mushoku Tensei.

A huge proportion of modern isekai (Re:Zero, Mushoku Tensei, Overlord, Slime, KonoSuba and many others) started as free amateur web serials hosted on a single Japanese user-generated-novel website — effectively the AO3 of the isekai boom — before being picked up by light-novel publishers. Name the platform.

AComico BPixiv Novels CShōsetsuka ni Narō (Narou) DNiconico Books

✓ Correct! Shōsetsuka ni Narō (literally “Let’s Become a Novelist”), commonly abbreviated to “Narou.” Launched in 2004, by the early 2010s it had become the dominant funnel for amateur isekai web novels — with publishers like Kadokawa and Shueisha trawling its leaderboards for hits to acquire. So many isekai LNs originated there that “Narou-kei” (Narou-style) became a publishing-industry shorthand for the genre’s tropes (overpowered protagonist, cheat skill, harem dynamics, RPG status screens).

✗ Wrong. The answer is Shōsetsuka ni Narō (Narou). Comico is a Korean-style webtoons platform. Pixiv Novels is a sister site to the Pixiv illustration platform but isn’t the dominant isekai pipeline. Niconico Books doesn’t exist as a major publishing platform. Narou is where the modern isekai boom was incubated.

Yet, as viewers get engrossed in the plot, the world, rather than taking cues from the game, relies on the lore built by its "novel system" chronicling its PvP conquests, and protagonist Lufas Maphaal is a quirkier, differently complicated isekai hero than Ainz Ooal Gown.

The anime briefly starts with a stint of one-sided battles in which Lufas subdues opponents like members of the Seven Luminaries, but truthfully, Lufas has some wildly compelling supporting characters. These include the femboy Aries, the astute golem Libra, and the elegant, loyal attendant Aigokeros, the latter of whom even joins Lufas' shadow like Beru or Igris from Solo Leveling.

Traces of Solo Leveling Can Be Found in A Wild Last Boss Appeared!

The series features Lufas wrestling with their dual identity, both as the male player and the female character he embodies. Moreover, Lufas encounters allies like the Twelve Heavenly Stars based on the traditional Zodiac with some Grecian tweaks while trying to regain the character's suppressed memories from childhood, with nefarious, manipulative forces pushing Lufas into conflicts with Exgate's world.

What's neat about A Wild Last Boss Appeared! is that, on top of its vibrant, colorful visuals and goofy isekai mechanics, including an RV Golem that eventually gets airplane wings, it also has some truly spectacular fights. One particular Heavenly Star, Libra, consistently steals the show with her mix of mecha combat tech and maid aesthetics, resembling One-Punch Man's Genos.

"Devil King too stronk! Please nerf!"

-Lufas Maphaal, A Wild Last Boss Appeared! episode #11

Another reason Solo Leveling fans should check it out, alongside One-Punch Man fans who loved the Boros fight, is that its director, Yūya Horiuchi, storyboarded some of the Solo Leveling anime's best moments. This includes the fateful Double Dungeon incident, and even Jinwoo's most touching emotional reunion. A Wild Last Boss Appeared! boasts similar levels of polish and care throughout season 1.

The isekai anime introduced an impressive array of characters, including lore about Lufas' race, and hints of an abused childhood that led her down her path before the player inhabited her. With even greater power hinted beneath the surface of Lufas' Level 1,000 state, it looks as though, like Jinwoo, there's still room to grow.

A Wild Last Boss Appeared! Season 2 Is Finally Bringing Back More Isekai Thrills

A Wild Last Boss Appeared! Season 2 main visual

Just one year after its debut, A Wild Last Boss Appeared! premiered its second season on September 26, 2026. This means the anime's continuation arrived more expediently than the upcoming Solo Leveling movie, offering something thrilling for viewers while waiting for the latter. After particularly exciting moments, like the watershed discovery in episode #10 and the laying out of the Goddess' Scenario, it becomes clear that the path awaiting Lufas is fraught with mysteries.

Beyond its top-tier action, the conspiracy looming over Lufas creates an aura of intrigue that casts constant doubt on the true nature of the characters, even her allies, ensuring that shocking revelations await viewers. So, alongside the powerful Black-Winged Boss gathering the Twelve Heavenly Stars, the series has been unveiling clues regarding Lufas's defeat 200 years ago. That means that, just as Sung Jinwoo is driven by the System and seeks to uncover the reason behind the gates on Earth in Solo Leveling, Lufas attempts to find answers about her summoning, her lost memories, and the game world.

Furthermore, the original novel of A Wild Last Boss Appeared! is relatively short, causing the anime to move at a fast pace, which is a departure from most isekai series that drag on without much progress. This becomes evident in the fact that, in this season, Lufas will already be battling Benetnasch, known as the strongest of the Seven Heroes. This makes A Wild Last Boss Appeared! Season 2 a must-watch anime for Fall 2026, especially for fans of Solo Leveling who are looking to follow another overpowered protagonist who defies everything in their path.
