Malty S. Melromarc

Malty S. Melromarc is the main antagonist of the series. She is the first Princess of Melromarc who betrayed Naofumi Iwatani by lying about him sexually assaulting her. Malty was first described by Naofumi as a lovely girl with wavy semi-long crimson hair that is tied up in a ponytail with chest-length hair strands hanging on either side, emerald-green eyes, a pretty cute and youthful facial features, yet slightly shorter than Naofumi. Malty normally presents herself to newcomers with her mask of a friendly and encouraging but flirty person. In reality, she is a malevolent psychopath with a myriad of negative traits. She is a consummate fraud who stands as prejudiced, narcissistic, egocentric, haughty, dishonest, hypocritical, whiny, bossy, corrupt, vain, arrogant, conceited, depraved, shrill, treacherous, condescending, malevolent, sadistic, abusive, deceitful, selfish and tyrannical. On top of being highly adept at cheating and manipulating people for her own self-serving benefit, while not above insulting or making them as miserable as possible. Malty is also a first-class actress, often pretending to be a poor and harmless girl who'd stoop so low as to self-victimize in order to make people believe her empty word. She is deceptive enough to "cry" crocodile tears in order to fool people into taking her side, something the Queen calls her out for in the manga. Even after she was implanted with a spell that makes her feel an immeasurable pain when she lies, lying remains Malty's first - and perhaps only - reaction in any given situation, even when there is clear evidence of her malicious actions. An example of this is seen when she denies her sister’s accusation of attempting to poison the food Naofumi was going to eat even though she was caught red-handed as she was pouring the poison into the meal in the anime.

Malty will do whatever it takes to get her way and is not above any kind of foul play, willfully interfering in otherwise fair matches. She will readily commit atrocities to gain an underhanded advantage while at the same time considering everything that may disfavor her side "unfair," revealing her to be a sore loser on top of being a scoundrel. Even going as far as attempting to kill her own sister so that she could be the future queen, manipulating her father into believing that Naofumi kidnapped Melty. Having "hypnotized" her into being on his side.

Malty is extravagant and goes as far as to use the country's treasury for her luxurious spending in daily life, cynically calling it "for the sake of the world." Her greed extends even towards villages ruined by the Catastrophe Waves, heavily taxing them beyond their means. Her mother mentioned that she already used her own body to gain some benefits - it is implied she went sexual on Motoyasu in order to better control him. In spite of visibly supporting (or pretending to support) Motoyasu, she is ultimately out for herself alone and stands ready to betray anyone, even her own relatives, for her personal desires and goals.

Despite being cunning and intelligent enough to manipulate others, Malty is shown to have several traits that makes her rather stupid and easy to fool herself. As shown where several characters were able to manipulate her easily provided that one knows her personality well enough to exploit these traits. As shown where, primarily due to her own inflated sense of exaggerated self-worth, on top of of her general over confidence, tended to make her quite dumb and easy fool if her ego is flattered appropriately. According to Mirellia and Melty, Malty hides in the shadows and enjoys bringing anguish to others. It is believed that the reason for such malicious behavior is because her father, Aultcray, spoiled her rotten growing up, letting her abuse her authority without consequences. Malty's lack of discipline and repulsive personality led to Melty being chosen as heir to the throne over her. she is the supreme commander of the mighty female lords army! if she can kill Naofumi Iwatani then males will be doomed! cause she hates males with a passion!
