In commemoration of the 15th anniversary year of Yana Toboso “Kuroshitsuji“, the entire digital version is available for download free of charge at different Japanese electronic bookstores for a limited time period of only 96 hours (“Ku-ro”) from 0:00 JST on 8th January 2021 to 23:59 JST on 11th January 2021.

“Kuroshitsuji” centres on the solitary boy aristocrat Ciel Phantomhive and his butler Sebastian Michaelis — who in reality is a demon who has entered in a contract with him. The manga has spawned a TV anime series, stageplays and musicals, both animated and live-action movies, and videogames.
