The Spring 2026 mystery anime list presents a selection of stories with different mystery directions. There are anime that focus on murder investigations, and there are also those that combine mystery with supernatural elements. For those of you who follow Spring 2026 mystery anime, these two titles are worth checking out.
2. MAO
MAO centers on Nanoka, a girl who time travels to the Taisho era. There, she is saved from a yokai attack by an exorcist named Mao. After returning to the present, Nanoka realizes that she has extraordinary new abilities.
Because of this change, Nanoka decides to go back in time to find answers. In the process, she gets involved in investigating a series of mysterious murder cases with Mao. From here, the story moves through the search for the origins of Nanoka's powers and the secrets that connect her to the supernatural world.
It was revealed that Mao and his sword were cursed by a cat demon named Byoki. Anyone other than the original owner who tried to use the sword would meet their end. But when Mao was in danger, Nanoka was able to lift and swing the sword. That fact is the key to the mystery in MAO.
1. Killed again, Mr. Detective.
Killed again, Mr. Detective. (Mata Korosarete Shimatta no desu ne, Tantei-sama) follows Sakuya Otsuki, the son of a legendary detective who wants to follow in his father's footsteps. In his investigation, he is accompanied by his assistant, Lilithea. This premise immediately puts mystery as the main focus of the story.
The uniqueness of this anime lies in Sakuya who keeps getting involved in murder cases as a victim. Every time she is killed, she will come back to life. After that, he continues the investigation with Lilithea. This pattern makes the investigation process feel different from ordinary mystery anime.
One of the cases introduced starts off as an investigation on a luxury yacht. From there, the incident develops into a bigger and bloodier case.
The two titles on this Spring 2026 mystery anime list offer different appeal. That difference makes the mystery line-up in Spring 2026 feel quite interesting to follow.
