Mask De Masculine

is a Quincy and a member of the Wandenreich's Sternritter with the designation "S".

Appearance
Mask has a very large, muscular build. He wears the standard Sternritter uniform, with the addition of a luchador mask covering most of his face, leaving his chin exposed. His mask has a star pattern on the forehead and thick markings around his eyes, nose, and cheeks. He has a mustache. In addition, he wears a wrestler champion's belt with a large rounded buckle rather than the standard Wandenreich belt buckle. On the buckle is the Wandenreich symbol.

Personality
Mask is a rather dull man. He had no idea a Shinigami lieutenant could perform Bankai, believing only a captain was able to perform such a feat.

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, Mask and the other Sternritter gather at the Gate of the Sun before traveling to the Seireitei in order to participate in the conquest of Soul Society. Once there, he blocks Renji Abarai's attempts to attack Äs Nödt. When Äs' hand is severely cut by Byakuya Kuchiki, Mask, berating his ally, is knocked down by Byakuya. As the battle between Äs, Byakuya, and Renji continues, Mask once again stops Renji from attacking, this time damaging his Shikai, when the lieutenant tries to activate his Bankai. Criticizing him for doing so, Äs states he could have stolen Renji's Bankai. Mask states he thought only captains had Bankai, prompting Äs to tell him to review the Daten they were given. When Ichigo Kurosaki later arrives in Soul Society, Mask is surprised when his reiatsu abruptly vanishes.

Later, Mask is present when Yhwach names Uryū Ishida as his successor, which surprises him. Afterwards, Mask, BG9, Cang Du, and Bazz-B discuss the news, with Mask questioning Bazz-B's request for an explanation. When Bazz-B leaps away, Mask asks him where he is going. When Bazz-B tells him he is going to Yhwach's chambers to protest, Mask, telling him to stop, states Yhwach will not forgive him if he does this.

Powers & Abilities
Great Spiritual Power: Mask's spiritual power is on a level comparable to or greater than that of a captain-level Shinigami.

Enhanced Strength: Mask has proven to be an incredibly strong man. When Renji Abarai attempted to activate his Bankai, Mask grabbed Zabimaru and performed a dropkick that sent Renji flying across the Seireitei, broke Zabimaru into pieces, and incapacitated the lieutenant.

Hirenkyaku Expert: Mask is deceptively fast for his build, repeatedly catching Renji off guard during their battle and leaving him very little time to react to his attacks. He grabbed Renji's Zabimaru just as he was about to activate his Bankai.

Enhanced Durability: Mask is a very durable man, grabbing Renji's released Zanpakutō without sustaining injury and emerging from the pit he fell into with only minor scratches.
