Black☆Star is an assassin, shadow weapon meister, and the last survivor of the infamous Star Clan taken in the DWMA and raised by Sid Barrett. In the DWMA, his weapon partner is Tsubaki Nakatsukasa, he is one of the top students in the academy as well as a former member of Spartoi. An assassin with an unusual trait of desiring to be in the spotlight, Black☆Star can be described as a wild meister in contrast to his calmer weapon partner with dreams of "transcending the gods". Eventually, Black☆Star also develops the goal of committing himself to master the Path of the Warrior. Initially, Black☆Star was remarked to be intensely self-centered by Stein, causing him to not take certain situations seriously and his arrogance causing him to be narcissistic and is visibly riled by those who he believes have or are wanting to take attention away from himself.
