Monspeet

Monspeet is a high-ranking demon and one of the elite Ten Commandments in The Seven Deadly Sins anime (also known as Nanatsu no Taizai), representing the Commandment of Reticence (or Silence).

In the anime adaptation, he appears as a calm, composed, and gentlemanly demon with neck-length dark brown hair, black eyes, a small mustache, and distinctive demon markings on the right side of his face. He typically wears a white cloak over his muscular, shirtless upper body, which is partially covered in dark matter-like substance.

He's portrayed as intelligent, reserved, and relatively laid-back compared to more aggressive Commandments, often speaking sparingly (fitting his Commandment theme, which punishes those who hold back their true feelings by muting them). He rarely indulges in unnecessary violence and prefers dialogue when possible, though he's fiercely protective—especially of his longtime partner Derieri, with whom he shares a deep, unspoken bond and acts as her close companion and interpreter.

Monspeet wields powerful fire-based magic (including hellfire capable of immense destruction and hindering regeneration), possesses extraordinary strength, speed, durability, and sensory abilities, and can transform into a destructive Indura form at great personal cost. In the anime, he's introduced after being unsealed from the Coffin of Eternal Darkness and plays a key antagonistic role in arcs involving the Commandments' revival and battles against the protagonists.
