Malty S Melromarc

Malty is the former first princess of Melromarc and also the first to join Iwatani Naofumi's party only to strip him and claim he raped her. Though she puts him through hell for a while, when the Queen, Mirelia Q Melromarc, returns from her trip in diplomatic relations she strips Malty of her name as a punishment for the false claims and renames her Bitch thanks to Naofumi's suggestion. Alternative acceptable names by royal decree include Whore and Slut. She did not repent for for her misdeeds and always tries to find ways to hurt or eliminate Naofumi as she believes it is his fault that she has had such misfortune. She has a twisted personality and tries to manipulate everyone. Uses fire magic and a bit of wind.

Background
To fix her bad personality. The Queen let her study abroad in a school in Foburei to learn cultures. But the result was... It was at the school in Foburei that that Witch graduated from her virgin status. She also met the King of Foburei during her time there, who was notorious for "drowning in carnal pleasure" and roughly treating women as "simple items for pleasure", and learns exactly why young noblewomen will go as far as committing suicide, rather than becoming one of the king's toys.

Heroes

 * Iwatani Naofumi: Malty is ultimately the cause of Naofumi's dark and cynical personality due to the fact that she betrayed him, stole all of his money, clothes and armour, and framed him for raping her for no other visible reason than to mess with him. Naofumi's originally kind personality snapped violently, he became distrustful of anyone who is not a slave, and for a very long time held contempt for women in general. Living with the stigmata she put his name for roughly two and a half months quickly made Naofumi a deeply jaded individual and if not for Raphtalia and Firo's later influence upon him it's debaitable whether or not he'd have endured. When Naofumi's name was cleared and she was punished by the Queen for her actions, she refused to learn anything at all from the experience and blames him for her current predicament, including having her name changed to "Bitch". When her revolution failed and she was told her fate was to be married off to Faubley's King(which is tantamount to a death sentence given that the man treats women as toys and takes truly horrific joy in breaking them), she was desperate enough to escape this fate that she even begged Naofumi to save her. Naofumi, rather predictably, didn't save her, even worse in fact he prevented her from comitting suicide to escape said fate and had Motoyasu escort her to the king and record everything that happened to her there so he could see it for himself, though it seems this was partly for the sake of closure. It's safe to say he is also aware by now that even if he had saved her she'd have just betrayed him at the first oppertunity later so not only did he hate her enough to let her die he also saw no point in saving her.
 * Kitamura Motoyasu: Motoyasu is the hero that Malty joins for most of the story. After betraying Naofumi, taking his stuff and framing him for raping her, she gives Motoyasu the stolen chain mail and convinces him to side with her. Motoyasu, due mostly to his gullibility, ends up being used by her to nearly take Raphtalia away from Naofumi as well. She seems to have sided with him purely because he has a good looking face. Later, when the charges on Naofumi were absolved by the Queen, Motoyasu refused to accept that Malty was the one who framed Naofumi for the longest time. After the Spirit Turtle incident, she abandons him completely, which causes his mentality to break to the point where he now sees all women(With exception to Philorilo Queens and some other women) as pigs, literally, and awoke his Curse Series indirectly. This came back to bite her harshly after her revolution failed and she was told that if any of the heroes spoke up for her she could be spared, Motoyasu could not understand her cries for help and only heard a pig squealing. This goes further when he is the one who ultimately escorts her delivery to the King of Faubley on Naofumi's order.
 * Amaki Ren: After the spirit turtle incident Malty approached Ren and took advantage of his emotional state to manipulate him and used him to escape from Naofumi arresting her. She later decided he'd be of little use, stole everything of value from him and joined Mald's revolution, causing his already fragile mental state to fall completely and succumb to the Curse Series of his sword. This definitely came back to bite her when her revolution failed and she was sentenced by the Queen. At this time she was told that if any one of the heroes spoke out for her she would be spared her fate, but Ren promptly told her to "go to hell".
 * Kawasumi Itsuki: After the Spirit Turtle incident broke him Malty and the revolutionaries under Mald took Itsuki into their custody, where they awoke his Curse Series weapons deliberately to study and use their brainwashing powers for the revolution. She also lied to Itsuki and manipulated him, directing his sense of justice towards opposition with Naofumi. After her revolution failed and she was told she could be spared if any of the heroes took her under their wing, Itsuki was absent entirely due to the state her actions left him in both indirectly and not.

Companions

 * Raphtalia: Understandably, Raptalia hates Malty for what she did to Naofumi, and holds her as a personal enemy. Malty seemed to consider Raphtalia nothing but an annoyance, and completely underestimated her during their final battle, which resulted in her complete defeat, subsequent arrest, and eventual execution.
