Mariella 「マリエラ Mariera[1] is a former assassin of the Diamond Kingdom that was tasked with bringing the deserters Fanzell Kruger and Dominante Code back to the kingdom,[2] but after encountering Asta, she chooses a different path of life.[3]


She is a voluptuous, fair-skinned young woman with pink eyes and short black hair.


Mariella is shown to be highly dangerous in combat since she is a former assassin, but is shown to be kind. While she feels she can't atone for the blood she has on her hands, she believes she can partially redeem herself by saving others. She also has a sharp tongue, insulting people and being brutally honest with people.


Mariella was born in the Diamond Kingdom and is trained by Fanzell Kruger. After becoming an assassin, she is ordered to recover her former teacher and his wife, Dominante Code, for deserting the kingdom. However, she is stopped by Asta and other Black Bulls and convinced to leave with Fanzell and Domina, settling outside of the Diamond Kingdom.[2]

In search of a cure for Asta's arms, Noelle Silva and Finral Roulacase visit the house of Mariella, Fanzell, and Domina. When Fanzell answers the door naked, Noelle blasts him with water, and Mariella asks that she be careful not to break their rundown house. However, when Domina starts hitting Fanzell for his inappropriate behavior, Mariella wonders if he will break before the house does.[4] After hearing what has happened to Asta, Mariella wants to help in order to repay the Black Bulls.[5]

The group returns to the Black Bull's headquarters, picks up a confused Asta, and rushes off to the Witches' Forest.[6]
