Brax Mizhine

Brax Mizhine (ブラクス＝マイズハイン) was a bloodline investigator living in, who appears posthumously in Toaru Majutsu no Index SS: Agnese's Magic Side Work Experience.

Background
At some point, Brax was visited by Albert Dying, leader of the Guild, who wanted him to appraise a stolen spiritual item, which he believed to be the genuine Sickle of Saturn, the powers of which were necessary to their plan to destroy Christian society. Wanting to earn extra money, Brax faked the appraisal and gave the item a false stamp of authenticity. Later on, after the fake spiritual item resulted in the ceremony failing and Albert nearly being killed by a Necessarius squad, losing subordinates and resources in the process, he returned to Brax's mansion and executed him, dismembering his body and storing the remains in his fridge in plastic containers and wrapping.
