About Black Butler

Kuroshitsuji (Black Butler) is a dark fantasy manga by Yana Toboso that has been serialized in Square Enix’s Monthly GFantasy since the October 2006 issue. Set in 19th-century England, the story follows the mysterious young butler Sebastian Michaelis of the Phantomhive family and his young master Ciel Phantomhive, who serves as the Queen’s “watchdog.” The series has now surpassed 36 million copies in circulation worldwide.

The previous anime installment, Black Butler -寄宿学校編- (Public School Arc), aired from April to June 2024. It followed Ciel as he received a letter from the Queen ordering him to investigate the disappearance of several students at the prestigious Weston College, leading Sebastian and Ciel to infiltrate the school and unravel the mystery.
