Malty S Melromarc/Chronology

Volume 1
Malty (under adventure name Myne Suphia) was Naofumi's first companion and party members in another world. After noticing that no one joined Naofumi's party, she switched from Motoyasu's party to join Naofumi's party.

At face value, she seems to have joined Naofumi's out of the kindness but secretly she was doing so take advantage of Naofumi's kindness.

She used Naofumi as a stepping stone to make him buy equipment for her using his money (by spending more than he could afford), she also stole Naofumi's chainmail and money which she gave to Motoyasu as a present and later accused Naofumi of a heinous crime he never committed - raping her - so she would be able to win Motoyasu over.

Her actions made Naofumi into a dark, cynical, and distrustful person. Naofumi was made out to be a criminal and made the other three heroes distrust him in the process.

Whenever Myne crosses paths with Naofumi, she will go to great lengths to cause him trouble. She coaxed Motoyasu to force Naofumi into a duel to free Raphtalia, his only trusted companion and source of inflicting damage. She even cheats in the otherwise fair match by interfering with magic.

The duel was announced as Motoyasu's win after Myne's interference. It was later discovered that Myne was actually the princess of the king and that her real name was Malty.

Volume 2
While rewarding the heroes, she persuades her father to deduce Naofumi's reward for freeing his slave. but didn't have her way. When Motoyasu was named as the lord of the village, she in his stead, levy heavy taxation on the wave affected the village. After receiving orders from higher authority to back down, she challenged the shield hero for the lordship of the village.

She also cheats by having her guards cast magic to slow down Naofumi and boost Motoyasu in their mounted race. Even though she denies this and has supporters agreeing with her, her antics have been called out by others outside her influence, mainly her mother's Shadows.

Volume 3
When Melty's life was under threat, she went along with the heroes and tried to "rescue" her. However, it has soon become clear that she actually attempted to murder Melty for the throne and frame Naofumi for this other crime. Ren and Itsuki both witnessed her unacceptable behavior, while Motoyasu once again remained oblivious.

Volume 4
She continuously hunts down Melty and Naofumi in an obsessive way, even to the point of burning down an entire forest to find them. Finally, when the Pope revealed the conspiracy, she turned pale and started blabbering. Naofumi, after a very hard fight, killed the diabolical Pope.

The Queen exposed all of Malty's crimes, stripped her of royalty and, as an extra punishment on Naofumi's suggestion, renamed her "Bitch" for her false rape claims. Alternative acceptable names by royal decree include "Whore" and "Slut." She had never repented for her misdeeds and always tried to find ways to hurt or eliminate Naofumi, as she believed her downfall and subsequent misfortunes was entirely his fault.
