Dark Rance

About
Dark Rance is the result of the union between Rance and the Devil Feliss. He was conceived during the events of Rance 5D, making him Rance's first official child in the canonical timeline.

Being a Devil himself, he ages quickly and already possesses a body of a human pre-teen by the events of Rance VI. Because of his birth, Feliss was sentenced to a thousand-year punishment, since a Devil giving birth to a human's child is considered an offense to the race. His initial goal was to kill his father Rance, drag his soul down to the Devil Realm and force him to save his mother. Dark Rance's true name is unknown, since it is a rule among Devils that if a human finds out his true name, he would be forced to servitude to that particular human, which is what happened to his mother. The name "Dark Rance" itself was a nickname suggested by  Sill.

Although failing to kill Rance, they did manage to rescue Feliss. However, the extensive torture and punishment resulted in her mind being broken and she's an empty shell of her former self. Dark Rance since then has decided to take matters into his own hands and protect his mother himself.

He's currently being protected by his father in the Rance Castle and lives there along with her mother to avoid pursuers, since they are considered fugitives by the Devils, they are chased by Angels for being Devils themselves. He's Rance's oldest son, having an younger brother named Rangi and a younger sister named Reset Kalar. Additionally, he also currently has four more brothers or sisters waiting to be born soon.

Personality and Appearance
Dark Rance is very similar to his father in appearance. His face and hair are very alike to his father's. However, this is only in looks since he isn't that similar to him in personality. Dark Rance actually despises Rance due to the misfortune he brought to his mother Feliss' life, who he loves very much and does his best to protect.

He's very rebellious and hostile towards his father, being also pretty childish and immature. The other members of Devil race showed little respect for him, due to his fretful and insurgent demeanor, and the fact that he's a newborn Devil. Despite this, Regaccio of the Three Devil Princes took a liking for him and is greatly fascinated by him. He claims that he foresees a great future for him and that he has "good eyes".

Abilities
Beffiting the son of the powerful adventurer Rance, Dark Rance shows an incredible amount of potential for combat with a naturally great skill for swordplay. Despite his feelings of grudge towards his father, his  fighting style has proven to be very similar to that of his despised  old man and relies more in brute strength and raw power to strike down his enemies, boosted by feelings of wrath and sorrow. Although being a newborn Devil, Dark Rance has shown unnatural growth in strength and may be the reason why he was given the sword Gram. He has proven to be a strong foe in battle and shown great potential and talent to become a very powerful Devil in the future despite his young age.

One of his most notorious traits is that he carries with him the Enchanted Sword Gram, a powerful blade forged by the mysterious blacksmith of the Devil Realm, the Devil Prince Regaccio. The sword has the absurd ability of of converting despair and anger into raw power, growing in size depending on the grief inside one's heart. This ability is frequently given good use by Dark Rance thanks to the constant series of unfortunate events his beloved mother goes through, allowing to grow stronger based on the suffering of his mother.
