The TV anime "You've been killed again, Detective-sama" will begin broadcasting and distribution on April 2nd. The main PV, main visual, and opening theme information have been released.

This work is based on a mystery novel by Teniwoha, who is also active as a Vocaloid P. Sakuya Oizuki, a high school detective with a special constitution that allows him to come back to life even if he is killed, takes on a variety of difficult cases by utilizing this constitution. The main PV starts with a scene where Sakuya wakes up from an eternal sleep on the lap of his assistant, Lilithea, and says ``I'm home'' as if nothing had happened. There is a scene in which Lilitea gently tells Sakuya, ``Welcome back. You've been killed again, Detective-sama.'' and a scene where Sakuya calmly replies, ``I'm safe,'' in front of Detective Maroki, who is surprised to hear ``He's alive!'', and Sakuya is shown at the crime scene. In addition, the upper part of the main visual features Sakuya and Lilitea, and the lower part features the inquisitive new actress Yuri Haigamine, Belka and Fido, a detective dog and assistant duo from England, Shardina, a flashy millionaire phantom thief, and Kunta Maroki, a detective involved in a case.
The opening theme will be Naohiro Hayashi's new song ``Stardust Eureka'' by his solo project, Multidimensional Control Mechanism Yodaka. This is a newly written song with Hayashi writing, composing, and arranging the song, and sound production by Tomoya Tabuchi (UNISON SQUARE GARDEN, THE KEBABS, Q-MHz). A comment arrived from Hayashi. Part of "Stardust Eureka" can also be heard in the main PV.
