Background
According to her mother and sister, Malty hides in the shadow and enjoys bringing misery to others.

Her actions made Naofumi into a dark, cynical, and distrustful person. She manipulated the other three heroes and the King, planning to use each other to retake her place in the palace following the Queen ousted ,renaming and disownment. her.

Whenever Malty crosses paths with Naofumi, she will go to great lengths to cause him trouble. On top of stealing from him and framing him for rape, she coaxed Motoyasu to force Naofumi into a duel to free Raphtalia, his only trusted companion and source of inflicting damage.

Volume 2

Later, Aultcray reveals to Naofumi that Malty firmly backed the Cult of three heroes's idea of hero summoning ceremony. This became his motivation and reason for summoning them without his wife consent.

Relationships
Legendary Heroes  Malty is ultimately the cause of Naofumi's dark and cynical personality due to the fact that she betrayed him and framed him for raping her for no other visible reason. 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. She continued to make him suffer by every means of opportunity, Like trying to take his slave and interfering in the duel for ownership of his slave, calling him a criminal and framing any crime possible. When Naofumi's name was cleared, the queen gave the choice of punishment for Malty to Naofumi. Malty uses her craftiness and appeal with perfect facial expression to Naofumi, with the intention of nullify her punishment. But was seen through and he demanded death penalty. This was the first and only time for Malty to call Naofumi by his name. After been talk down, her punishment was having her name changed to "Bitch".
 * Naofumi Iwatani:

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 of her being the victim. Motoyasu completely trust her. Motoyasu, due mostly to his gullibility, ends up being used by her in most cases, such as leading him to nearly take Raphtalia away from Naofumi, levying heavy tax on the village after Motoyasu became it's lord. She seems to have sided with him purely because he has a good looking face. She easily convinced Motoyasu of falsely claiming Naofumi of having brainwashing shield by which he supposedly brainwashed the people, kidnapping second princess and killing Ren and Itsuku.
 * Motoyasu Kitamura:

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; Motoyasu also seemed to pay little attention to Malty's suspicious behavior such as she giving hard time for other female party members and kicking them out(even selling the one named Rino as slave to a noble), her exceptionally wasteful spending which she claims it was for the "for the sake of the world," and also her attempt to kill Melty which Ren and Itsuki notices, but he didn't. Motoyasu even agreed to shoulder her debt to some extent. After the Spirit Tortoise incident, she abandons him completely. After seeing her badmouthing him to Ren of many false charges which causes his mentality to break to the point where he now sees all women(With exception to Filolial Queens and some other women) as pigs, literally, and awoke his Curse Series indirectly.

In "The Reprise of the Spear Hero" Motoyasu still recognizes Malty, to some extent as he can only see and hear her as a pig, thus he was always wary of her and warn others about her.

Ren believes her accusation of Naofumi's attempt to rape her and berates Naofumi without hearing his side of story. Later, Ren along with Itsuki points her involvement in the foul play of duel between Naofumi & Motoyasu and stand for Naofumi. Ren was the first to notice Malty's attempt to kill Melty and begins to suspect of deeper and starts his investigation with Itsuki. When all of her crimes brought to light by the queen while clearing Naofumi's charges, Ren along with Itsuki agrees with the punishment to Malty befitting. After the spirit tortoise incident Malty approached Ren and took advantage of his emotional state to manipulate him and used him to escape from Naofumi arresting her.

 * Itsuki Kawasumi:

Vassal Wielders 

Aultcray, the hero of the cane was her father. He was a doting parent and spoiled her too much. Most of her evil personality stems from this brought up or at least what it was thought. Even if she causes any trouble she pins it on someone else and he will punish the victim without any thoughts. She gets away from anything with the help of her father. Trash supported Malty in framing Naofumi of fake rape crime. As a king, He gave too much preferential treatment for the spear Hero with sole reason of Malty being in his party and favoring him.

Notably, despite how she had betrayed Motoyasu, Ren and Malty. She remained royal to Malty, until Malty's failed rebellion. Naofumi not knowing her name called her "Woman 2".
