Malty S Melromarc

Bitch (ビッチ), previously known as Malty S Melromarc (マルティ＝S＝メルロマルク), is the former first Princess of Melromarc and the primary antagonist of the series. She betrayed Naofumi as lying that he raped her.

Appearance
Malty was first described by Naofumi as a lovely girl with semi-long crimson hair, emerald-green eyes, pretty cute and youthful facial features, yet slightly shorter than Naofumi. Even after her betrayal, Naofumi admits that she is a waste of beauty and describes her as needlessly attractive.

Personality
Malty normally presents herself to newcomers with her mask of a friendly, encouraging and flirty person, but actually, she is a malevolent psychopath with a myriad of negative traits - she is a pathological liar, prejudiced, narcissist, egocentric, haughty, dishonest, corrupt, arrogant, amoral, treacherous, sinister, sadistic, abusive, deceitful, selfish and tyrannical. She is shown to be highly adept at lying and manipulating people, and is not above insulting and making them as miserable as possible. She is deceptive enough to "cry" crocodile tears in order to fool people into taking her side.

Malty will do anything to get what she wants and is not above any kind of foul play, willfully interfering in otherwise fair matches. She will readily cheat to gain the advantage while at the same time considering everything that may unfavor her side "unfair," revealing her to be a sore loser and a hypocrite as well.

Malty is extravagant and goes as far as to use the country's treasury for the luxurious spending of her 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 simply for her entry and exit. 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 blood relatives, for her egotistical and personal desires.

Background
According to her mother and sister, Malty hides in the shadows and enjoys bringing misery to others. It is believed that the reason for her malicious behavior is because her father, Aultcray, spoiled her while she was growing up, causing her to abuse her authority without any consequences. Her lack of discipline and repulsive personality led to her younger sister Melty to be chosen as heir apparent to the throne over her.

To fix her bad personality, the Queen sent her to study abroad in a school at Faubley. However, all that accomplished was Malty's "graduation" from virginity.

 * Queen Melromarc has stated that Malty was not a virgin and has implied her daughter has had quite a few lovers.
