Moss

Moss (モス) is an Archduke in the Daemon Realm and one of Testarossa's subordinates. He has stood undefeated for tens of thousand of years, with his strength second only to the Primordial s. Along with Cien, he serves as Testarossa's lieutenant.

Appearance
He assumes the appearance of an adorable young boy who, according to Rimuru, looks like an elementary school student in 5th or 6th grade. He has ash-grey hair. From appearances alone he doesn't come off as intimidating at all, even though he's a super old daemon who's lived several millennia.

Personality
He usually holds a calm and levelheaded disposition in contrast with his appearance, and is fairly intelligent. In the presence of his superiors, Moss gets super timid, to the point his own presence in the room thins out. He is very loyal—attending to Testarossa for several millennia in spite of her personality is proof of that—and he shows extreme humbleness whenever praised. He's quick to rage when his master is insulted in any manner and will proceed to ruthlessly kill the offender unless it goes against his orders.

Background
A Daemon of the pre-historic species and a high ranking figure of the ruling class in the Daemon world; he is a subordinate of Blanc. In the past, he often dueled the unnamed Veyron numerous times and always emerged victorious, cursing the latter to a fate of repeated reincarnations. One day he, along with his master, were recruited by Diablo to serve Rimuru. Initially, he opposed Diablo's demands (as with several others), but after taking a harsh beating, he reluctantly bent to his coercion in the end. Upon meeting Rimuru and acquiring a body, he and Blanc received the names "Moss" and "Testarossa", respectively, and evolved to Daemon Lords. The two have since pledged their loyalties to Rimuru and settled in Tempest as their new home. Moss specializes in reconnaissance and espionage, similar to Souei. He's also an officer in the Black Numbers reporting directly to Diablo, with Testarossa acting as his superior officer. He frequently escorts Testarossa as her aide in her new post as Military Attaché. undefined

Relationships

 * Testarossa: He's highly devoted to her. It's an accomplishment that he stood at her side for as long as he has despite how egocentric she can be, a testament to his loyalty. Moss does not tolerate any insult towards her. He's very quick to amend his conduct when pissing her off.
 * Rimuru Tempest: He gave him both a name and body. Moss admires his wisdom and foresight and like all of Rimuru's subordinates, does not tolerate disrespect towards him.
 * Diablo: His boss and superior. After folding to his coercion, Moss now serves as his officer in the Black Numbers.
 * Souei: They work together per Rimuru's recommendation, their similar talents and capabilities complement each other well enough that they cooperate from time to time.
 * Veyron: They've dueled several times in the Underworld and now operate in Tempest together as fellow Officers of the Black Numbers.
 * Cien: A fellow lieutenant of Testarossa. They serve as Officers of the Black Numbers.
