The TV anime adaptation of Kogitsunemaru's Possibly the Greatest Alchemist of All Time light novel series has released its first trailer. A key visual was also released for the upcoming isekai fantasy anime, revealing two more characters, and the voice actors playing them. The anime is scheduled to premiere in January 2025.
The trailer introduces protagonist Takumi Iruma who acquires the "cheat skill" known as alchemy, and because of this, he becomes a wealthy merchant. There's also footage of him interacting with the other characters he meets in the new world he's summoned to, and it looks like there's going to be a lot of sorcery and fantasy spectacles in this anime.
