Aniplex of America describes the original television series:

Years after the Fourth Holy Grail War of Fate/Zero, Waver Velvet—the boy who fought alongside Iskandar, the King of Conquerors—has assumed the title Lord El Melloi II. In this position, he takes on myriad magical and mystical mysteries for the Clock Tower, the mecca of the magecraft world.

Based on the popular novel by Makoto Sanda, this incredible story has finally been adapted into an animated title. This series sees the beloved “Rail Zeppelin” arc brought to life, along with original episodes to lead into this exciting story.

Prepare yourself! This epic adventure is about to leave the station!

The television anime premiered in Japan in July 2019. Crunchyroll streamed the anime as it aired in Japan. Funimation also streamed the anime. Anime Expo screened the U.S. premiere of the first two episodes in July 2019.

Makoto Katō (Beautiful Bones -Sakurako's Investigation-, Bloom Into You) directed the series at TROYCA. Ukyō Kodachi (Chaos Dragon, Boruto: Naruto Next Generations) was in charge of series composition. Jun Nakai (GATE, Silver Spoon) designed the characters. Ei Aoki (Fate/Zero director) was credited as supervisor. Yuki Kajiura composed and arranged the show's opening theme song "starting the case: Rail Zeppelin."

Makoto Sanda's original novels center on the titular character Lord El-Melloi II — the adult Waver Velvet from Fate/Zero, and successor of Kayneth — as well as Lord El-Melloi II's apprentice Gray. The story takes place in the Clock Tower, the Mage's Association's headquarters in England. There, Lord El-Melloi II and Gray solve various mysteries of a magical nature surrounding the Mage's Association.

Sanda launched a sequel novel series, Lord El-Melloi II-sei no Bōken (The Adventures of Lord El-Melloi II), in December 2020.
