Possibly the Greatest Alchemist of All Time [Season 1 Episode 12]

Episode 12 Review: “Possibly the Greatest Alchemist of All Time” Wraps Up Season 1 with a Bang

Warning: Spoilers ahead!

If you’ve been following Possibly the Greatest Alchemist of All Time, you already know it’s the kind of isekai that doesn’t take itself too seriously—until it suddenly does. Episode 12, the season finale, delivers a mix of chaos, character growth, and just enough loose ends to leave fans begging for Season 2.

The Plot Thickens (and Then Explodes)

Takumi Iruma, our accidental OP alchemist, finally faces the consequences of his world-breaking skills. The episode kicks off with the Wedgefort conflict reaching its boiling point, as Sidonia’s so-called “heroes” reveal their true, horrifying colors. Fans on MyAnimeList pointed out how the show cleverly subverts expectations—what starts as a typical “build-a-kingdom” arc quickly spirals into moral dilemmas and brutal betrayals.

One Reddit user summed it up perfectly: “This episode was like watching a D&D campaign where the DM finally snaps and punishes the murderhobos.” And honestly? It’s satisfying. Takumi, who just wanted a quiet life making toilets and silk underwear, is forced to step up as the voice of reason—while still being hilariously awkward about it.

Character Arcs: From Toilets to Trauma

The finale gives some much-needed depth to the supporting cast. Maria and Sophia, Takumi’s “employees” (let’s be real, they’re his found family), shine in their roles. Sophia’s growth from a cursed elf to a powerhouse is a fan favorite, with one commenter joking, “She went from ‘I hate humans’ to ‘I will murder for this nerd’ in record time.”

Meanwhile, Maple, the spider-girl-turned-human(ish), continues to steal scenes. Her dynamic with Takumi is equal parts adorable and weird—like when she blocks his pervy thoughts about her silk-made underwear. Fans are divided on whether this is endearing or cringe, but hey, it’s on-brand for the series.

The Good, the Bad, and the Ridiculous

Let’s address the elephant in the room: the show’s obsession with slavery. Episode 12 doesn’t shy away from the controversy, but it does try to justify it with… questionable logic. One MyAnimeList user sarcastically noted, “Ah yes, slavery is fine as long as you’re nice about it.” Another added, “At least the girls get cool armor out of it—even if that ‘armor’ is just a metal bra and a frilly skirt.”

The humor is hit-or-miss, too. Takumi’s reactions range from relatable (freaking out over sudden responsibility) to downright baffling (why is a 40-year-old salaryman blushing over underwear?). But as one fan put it, “It’s so dumb, but I can’t stop watching.”

Final Verdict: A Solid Setup for Season 2

Episode 12 wraps up Season 1 with a mix of action, emotion, and just enough unanswered questions to keep fans hooked. The animation stays consistent (though Maple’s spider legs are still suspiciously absent), and the voice acting—especially Sora Amamiya as the goddess—adds charm to even the silliest moments.

Is it the greatest isekai of all time? Probably not. But as one Redditor said, “It’s like junk food—you know it’s not good for you, but you’ll still binge the whole season in one sitting.”

Rating: 7.5/10 – Flawed but fun, with enough potential to make Season 2 a must-watch.
