Black☆Star is one of the main Meisters followed in the series. He is a survivor of the notorious Star Clan, alongside Akane☆Hoshi, which explains the star symbol on his shoulder. His Demon Weapon partner is Tsubaki Nakatsukasa. Black☆Star is a Shadow Weapon Meister (暗器職人 Anki Shokunin in Japanese), known as Dark Arm Meister in the English dub. Presently, he holds the rank of Two-Star Meister and is part of the elite student unit, Spartoi.
He descends from White Star, a formidable and lethal assassin whom Mifune had previously fought. Similar to his ancestor, Black☆Star harbors a grudge, particularly against Mifune, who had defeated him twice before. Overcome with rage, he eventually confronts Mifune and emerges victorious, mastering Tsubaki's enchanted sword mode in the process and defeating Mifune fairly.
In the manga, Black☆Star arrives at Baba Yaga Castle for a showdown with Mifune. Before the fight starts, Mifune remarks, "This is the third time, there won't be a next." As the battle concludes, Black☆Star stabs Mifune with his sword. With his body fading away, Mifune asks Tsubaki to bring him as close to the castle as possible.
