Along with his skills with a sword, Kuroi has several quirks, which include poetry referencing Black Sabbath appearing whenever he does. In addition, Kuroi is so obsessed with ageless beauty that he used taxidermy to preserve the heads of his female victims and stuffs them to preserve their beauty forever and sews them upon his shoulders. He did this with his wife and Rin's mother presumably just after beheading her father.
Founding of the Itto-ryuEdit
Sabato is presumably the first member to join Itto-ryu, as he is around when Anotsu is a child. He is a skilled pupil under Anotsu Saburō (Anotsu Kagehisa's grandfather) and a master swordsman. When Kagehisa Anotsu was a child he helped him in the founding of Itto-Ryu.
End of the Mutenichi-ryūEdit
When Anotsu and some of the other "core" Itto-ryu members invade Rin's father's Mutenichi-ryu Dojo, Kuroi is the one who ultimately kills Kurose, and O-Toki Asano. Somewhere along the two years before the start of the story of Blade of the Immortal, Sabato stuffs, and mounts O-toki's head upon his shoulder.
Manji vs. KuroiEdit
When Manji and Rin first start traveling together they encounter Kuroi by a stream. Kuroi easily defeats Manji, and Rin, his Mask is destroyed revealing the two heads perched upon his shoulders. He wanted to take off his wife's head to replace it with that of Rin promising that he will end his own life if Rin gave up, but he was killed by Manji, unaware of his immortality, before he could go through with this. Kuroi is the first member of the Itto-ryu to be shown killed, and the two shuriken he uses which are called Karasu, or "The Crow" are taken temporarily by Manji.
Equipment and AbilitiesEdit
Sabato Kuroi carries around two un-named Katana, and two Shuriken that he calls Karasu or "the Crow".
Even though Kuroi was extremely powerful, and easily defeated both Manji, and Rin in battle, he is one of the Itto-ryu members Manji fought before Magatsu, so he knew nothing of Manji's immortality, and completely under estimated him, which lead to his downfall.
Kuroi Sabato is inspired by the band Black Sabbath; Kuroi Sabato roughly translates into Black Sabbath from Japanese. Kuroi is a direct translation to the color black. Sabato when romanized, can be taken as "Sabbath." Black Sabbath is known to be one of Hiroaki Samura's favorite bands.
