Izure Saikyou no Renkinjutsushi?

A salaryman is surprised to find himself summoned to another world by accident. With no way of returning to Earth, he receives the name Takumi Iruma, a different younger body, magic powers, and a fresh start in an unfamiliar land. To preserve his quiet life, Takumi settles in a local village and assumes the job of an alchemist, allowing him to create almost anything he desires. Making the most of his time, he explores his new abilities and even tames an unlikely pet.

However, Takumi decides to move on to a big city in hopes of improving his alchemy skills and business. As he keeps learning about his profession and gaining new connections, Takumi might just be able to become the greatest alchemist of all time.

Review: Possibly the Greatest Alchemist of All Time

I just finished watching all 12 episodes of Possibly the Greatest Alchemist of All Time in one sitting, and I have to say—it was a fantastic experience! What really stood out to me was how refreshing this anime felt, despite being labeled as a harem. Unlike most harem anime, the main character wasn’t a pervert, and there was no forced romance or awkward ecchi moments. Instead, the story focused on genuine bonds between the characters, which made it feel much more meaningful.

The dynamic between the characters was truly the heart of the show. It felt less like a ... harem and more like a found family—a group of misfits who helped each other break free from their past struggles. The relationships weren’t about attraction or shallow infatuation, but rather about trust, support, and personal growth. Each character had their own burdens, and together, they gave each other the strength to move forward.

The storytelling was also really well done. It wasn’t just about action or adventure; it had emotional depth that kept me invested from start to finish. Even though it’s a fantasy anime with alchemy and magic, the way the characters connected felt incredibly real.

Overall, Possibly the Greatest Alchemist of All Time was a genuinely good anime. It defied expectations, delivering something heartfelt rather than just another generic harem story. If you’re looking for an anime with strong character bonds and a wholesome atmosphere, I’d highly recommend giving this one a watch!

This is good trash isekai, and I say that from a place of love for trash isekai.

This has all the ingredients that make a solid trash isekai in place and a unique-enough story. It's a lighthearted and enjoyable watch if you're looking to throw something on with all the tropes you would expect.

But at the same time there's nothing particularly special about it either. There's the standard OP main character that gets tossed into another world, gets stronger every episode, has a handful of challenges that are easily resolved, and minor struggles throughout. There's a fair amount of world building and some predictable character building.

If ... you like trash isekei, you'll probably enjoy this. If you're looking for something deeper or highly engaging, you'll probably want to give this a miss.

No - even for a trash isekai fan this is not a good isekai. Takumi gets alchemy and literally every other skill and starts making everything from toilets, to inter-dimensional wagons, to pocket storage. There isn't anything he cannot do, but the magic system is all over the place making it annoying to grasp. You never get a very satisfying OP protagonist moment.

The saving grace is that the plot is fast. It felt like every two episodes might be covering a new story arc, sometimes a single episode felt like it covered what a normal LN would take a entire volume to cover. The ... events themselves might have been acceptable if the animation wasn't abysmal. Every action scene is a shot of a single still frame with movement lines drawn on them. As a viewer there is no excitement brought by watching this show, and with a lackluster story everything else falls apart.

Yes, there is a lot of slavery in this as well - and girls who protest being released from their slave contracts. The other summoned Japanese people are constantly shown and are mostly irrelevant, but they spend 2-3 minutes each episodes showing them being generically evil. Takumi doesn't develop at all as a character; maybe towards how he views his slaves, but nothing that distinguishes him over any other protagonist. It feels like he just reacts as a nice guy would to everything going on around him.

Overall, i would suggest watching any other isekai that has somewhat half decent animation over this show.
