Anime

An anime television series adaptation was announced on March 13, 2026.

Reception

The 12th manga volume, released in February 2024, stated that the series had sold over 1.5 million copies.

Rebecca Silverman of Anime News Network reviewed the first manga volume, stating that the series' premise was better than its execution. Despite being interested in the concept, she found the pacing to be too fast, not giving enough time for the plot or characters to be fleshed out. She also questioned the lack of consequences for various plot points, which she suggests was a result of the book's pacing. She wondered if this was the fault of the adaptation or was an issue with the original novels.
