Based on the light novels by Kogitsunemaru, Naoyuki Kuzuya (Reborn to Master the Blade: From Hero-King to Extraordinary Squire) directs Possibly the Greatest Alchemist of All Time at Studio Comet, with series composition by Mitsutaka Hirota (Helck), character designs by Sayaka Anezaki and music by Hiroshi Nakamura (Sweet Reincarnation).
Crunchyroll describes the story:
Iruma Takumi finds himself caught up in a hero summoning, even though he’s not a hero. Summoned by mistake to Mildgard, a fantasy world of swords and magic, Takumi is given a chance to start over. Though he dreams of a peaceful life, the goddess Nolyn grants him “alchemy,” an ultra-powerful skill that allows him to create anything from holy swords to flying ships. His reluctant adventure begins!
