Possibly the Greatest Alchemist of All Time (Seasons 1–2)

Possibly the Greatest Alchemist of All Time (2025) is a Japanese isekai anime you can watch online on iFILM. Takumi Iruma, an ordinary office worker, gets swept into a hero summoning ritual he was never meant to be part of.

By mistake he lands in Mildgard, a fantasy realm of swords and sorcery. The goddess Nolyn hands him a fresh start: a younger body, a new face, and a skill she calls "alchemy." It sounds like a modest craftsman's gift, but it lets him forge almost anything, from holy blades to flying ships. All Takumi wants is a quiet life making things for a living. A power like that, though, refuses to stay low-key, and soon both the people who need his help and those who want to exploit it come knocking.

The show takes the familiar isekai setup and leans into the contrast: a hero with no interest in saving the world, just a workshop and a day off. Light comedy, crafting fantasy and unhurried world-building make it easy evening viewing. Fans of the overpowered-newcomer subgenre will feel right at home.
