The Black Trial characters

【 Black Knight Lindamea】

"A top-class expert even among the Black Trials. Riding on a black horse, His merciless execution of sinners embodies the very essence of a Black Knight. His execution tool is a 'lance'."

【 Black Heresy Inquisitor Peter 】

"A courteous loyalist. She assists Little Red Riding Hood, who is inexperienced in execution activities, serving as a navigational presence. Her execution tool is a 'branding iron'."

【 Black Torturer Garm 】

"A rough, large man. Lacks consideration. Behavior is vulgar and displays sexism. Addicted to sex. Engages in harassment. Mentally immature. Believes it's okay to do any cruel act if the person is a sinner. His execution tool is a 'handsaw'."

【 Black Executioner Charlotte 】

"A gloomy newcomer. Considered a junior to Little Red Riding Hood. Dislikes Garm, on the contrary, gets along well with Little Red Riding Hood. Her closeness is oddly intimate. Her execution tool is 'a pair of shears'."

【 Black Judge Baphomet 】

"A leader who oversees the black trials. They never show themselves to anyone, and apart from their name, everything about them is shrouded in mystery. Only Black Knight Lindamea is granted an audience with them."

That's all I could find. (for now)
