I Left My A-Rank Party

“How the Mighty Have Fallen”

Winter 2025 came in swinging. Solo Leveling returned, Sakamoto Days finally got its adaptation, and the seasonal lineup had enough firepower to keep even the most jaded fans engaged. But stacked seasons have a way of exposing the weak links, and I Left My A-Rank Party to Help My Former Students Reach the Dungeon Depths! turned out to be one of the weakest. This is a show that had a recognizable studio, a 24-episode run, and a premise that at least sounded like it could go somewhere—a veteran adventurer leaves an ungrateful party and joins up with a group of his former female students to tackle dungeons together. On paper, it reads like a dungeon-crawler with harem trappings and room to develop its cast. In practice, it fumbles nearly every opportunity it creates for itself. Here's where it went wrong, why even its studio pedigree couldn't save it, and who—if anyone—should bother watching.

I Left My A-Rank Party is adapted from Kousuke Unagi's light novel, which was serialized on the web novel platform Shousetsuka ni Narou from October 2020 to February 2025 before being picked up by Kodansha under their Ranobe Books imprint for five volumes. A manga adaptation illustrated by Yuuri has been running since June 2021 via Kodansha's Magazine Pocket platform and currently has twelve collected volumes. The English-language manga is available digitally through Kodansha USA's K Manga service. The light novel has not been officially translated into English as of this writing.

Bandai Namco Pictures produced the anime adaptation—yes, the studio behind Gintama, Welcome to Demon School! Iruma-kun and the Symphogear franchise—and aired for two consecutive cours (24 episodes) from January 12 to June 29, 2025, on Nippon TV. It streams on Crunchyroll with both sub and dub available. Direction comes from Katsumi Ono, whose resume includes Yu-Gi-Oh! 5D's, Yu-Gi-Oh! Arc-V and Skeleton Knight in Another World. Series composition and scripts were handled by Kazuyuki Fudeyasu, a prolific writer with credits on everything from JoJo's Bizarre Adventure to That Time I Got Reincarnated as a Slime. Character designs are by Masakazu Yamazaki, and the music was composed by Go Sakabe, known for the Date A Live series and multiple Kamen Rider entries. A second season has already been announced.

Those are serious names on the production sheet, which makes the end result that much harder to explain.

The premise is straightforward: Yuke Feldio, a Red Mage and Alchemist, spends five years as a support player in the A-Rank party Thunder Pike, only to be treated like dead weight by his teammates. He quits, runs into his former student Marina, and gets recruited into her D-Rank party alongside Silk and Rain. They form Clover, start dungeon-crawling, and livestream their adventures using a magical flying camera called Camelat-kun. Along the way, more women join the party — the ninja cat-girl Nene, the former Thunder Pike mage Jamie, and eventually a mysterious young girl named Niberune — and the harem element takes over completely.

The show's central problem is that it cannot decide what it wants to be. The dungeon-exploration hook gets abandoned for long stretches in favor of domestic scenes and harem gags that don't land with enough frequency or specificity to justify the screen time. When the plot does try to escalate — Thunder Pike's downfall, the Achromatic Darkness arc, a slave-collar subplot involving Rain — it rushes through the material so quickly that nothing carries its emotional weight. Episodes alternate between info-dumps about magic systems that never become relevant again and character interactions that vanish from memory by the next week's episode. The pacing across 24 episodes is remarkably uneven for a two-cour show with a single scriptwriter handling composition. Fudeyasu has shown he can manage long-form structure elsewhere; here, the source material may simply not have given him enough to work with.

The isekai-adjacent space has exhausted the "underestimated hero proves everyone wrong" framework. However, there's still a version of this story that works if the execution is tight. This isn't it. The show bites off more than it can chew by trying to blend dungeon-crawling, harem comedy, political intrigue, and streaming culture into a single narrative, and none of those threads get the attention they need to develop properly.

Yuke Feldio is the kind of protagonist who is supposed to be overpowered but humble, the sensei who doesn't realize how strong he is. The problem is that the show never makes you feel his frustration from the Thunder Pike years or his growth within Clover. He's competent from minute one, and his relationships with the party members are defined more by their feelings for him than by anything he does to earn them. There's no tension in a character who can solo a floor boss in episode one and never faces a real challenge to his abilities or worldview.

Marina, the swordswoman and de facto recruiter of Clover, has the most natural chemistry with Yuke but gets sidelined once the harem expands. Silk, the dark elf ranger, has an interesting background that the show gestures at without developing. Rain, the priest, carries the most emotionally charged subplot—her backstory involves a slave collar and an abusive nobleman named Besio. Still, the resolution is handled so quickly that it feels like a checkbox rather than a character moment. Nene appears with almost no buildup or introduction; viewers of the anime have noted she feels inserted into the story rather than integrated into it. Jamie's arc, defecting from Thunder Pike after their corruption is exposed, has real potential but is compressed into too few episodes to breathe.

On the antagonist side, Simon from Thunder Pike functions as the primary villain for the first half. Still, his motivations are so one-note — jealousy and entitlement — that he never becomes a credible threat. The show telegraphs every beat of his downfall well in advance. The cast is large and continues to grow, but breadth without depth is a recurring problem in harem series. None of the women felt like they existed outside their relationship to Yuke, flattening every interaction into the same dynamic, repeated with different character designs.

This is the aspect where the Bandai Namco Pictures name causes the most disappointment. The studio has demonstrated real visual ambition in its flagship properties—the fluid fight choreography of Gintama's serious arcs, the color-saturated energy of Iruma-kun—but almost none of that shows up here. The animation stays functional at best and outright stiff during action sequences that should be the show's bread and butter. Dungeon environments are rendered with flat backgrounds that never convey scale or atmosphere. A fantasy setting built around magic combat and monster encounters should be a showcase for dynamic effects work. Instead, the show delivers the visual equivalent of a budget allocation you can feel on screen.

The use of CG for monsters and certain environmental elements clashes noticeably with the 2D character art, creating a visual mismatch that pulls you out of scenes that are supposed to be the dramatic highlights. Character designs are clean but generic—you've seen these archetypes drawn this way a dozen times in similar shows. For a 24-episode commitment from a studio with this pedigree, the production values suggest the series was not a priority project. The fact that Nakamura Production handled significant key animation outsourcing across multiple episodes reinforces that impression.

The music is genuinely the show's strongest element, which says something about the state of everything else. The opening theme, "Enter" by L.E.I. (Kazuma Kawamura of The Rampage from Exile Tribe), is an energetic track with a hook that caught me off guard—it's better than a show of this caliber deserves, frankly. It has a propulsive, almost idol-pop energy that at least makes you feel like you're about to watch something with momentum.

The ending theme situation is more captivating than you'd expect: Yuki Tanaka (who also voices the character Niberune) performed all three EDs—"Treasure Chest" for episodes 1-9, "Mirror" for episodes 10-17, and "Tapestry" for the final stretch. "Treasure Chest" is a pleasant lyrical pop track that sets a warmer tone after each episode, and "Mirror" shifts to something slightly more reflective as the story tries to deepen. None of them is awful. They're just attached to a show that doesn't match their quality. Go Sakabe's background score does its job without being particularly memorable. Sakabe has shown he can deliver atmospheric, character-driven work—his Date A Live scores have real personality, and tokusatsu fans genuinely belove his Kamen Rider entries—but the material here doesn't give him much to work with. The OST fills space competently without elevating any scene the way a strong score can.

A 4 out o10 is where this lands, and the score reflects the gap between what this show could have been and what it actually delivered. The premise had potential. The studio had the capability. The staff had the resumes. But none of that matters when the story lacks direction, the characters lack depth, the animation lacks ambition, and the pacing can't hold a 24-episode run together. Even the harem element, ostensibly the show's identity, fails to deliver the chemistry or comedy that makes that genre work when it's done well. A second season is already confirmed, but the show's mid-6.55 to 6.6 score on MyAnimeList and its near-total absence from seasonal conversation suggest the audience has largely moved on. The light novel source material only has two more volumes to adapt, so a shorter second run is likely — and honestly, tighter might be better for this property.

If you're a die-hard Bandai Namco Pictures completionist or a committed harem fan who has exhausted every other option on the shelf, you might find enough here to get through. But if you came looking for dungeon-crawling with real stakes, monster encounters with visual weight, or a party dynamic that earns its emotional beats, this is not the show. Winter 2025 offered numerous better options for spending your time, and this one was overlooked for good reason.
