Chaos

About
Chaos is one of the only two swords on The Continent that can harm Dark Lords and the Demon King by going through their invincibility fields. He used to be a human thief from the GL era, and was originally a member of The Legendary Five, but after a certain quest he was transformed into a sword along with the samurai Nikkou.

Chaos was used by Gi to pierce Demon King Gele's heart and seal her in a void dimension. Chaos remained hidden in the depths of the former Demon King Castle of that time, that would later be used by Gross Leazas to make the Leazas Castle and establish the capital of his new Kingdom of Leazas.

As a result, for centuries Chaos remained hidden in the Leazas Castle sealing Gele and only the royal family knows about his real whereabouts. During the events of Rance 03, Chaos was removed by Dark Lord Noce in order to release Gele and Rance wielded him in order to defeat the Dark Lords and the re-awakened Demon King.

He is currently Rance's partner, and a counterpart to his old comrade the Holy Sword Nikkou.

Personality and Appearance
Although he is referred to as "The Black Sword", his blade is actually a silver color. He's far more lightweight than you'd expect. He has three yellow eyes, two near the base of the hilt and one at the pommel, he has a decorative jewel between his eyes.

Despite being a sword, he retained the ability to speak. His character is very similar to Rance's, they both get along and considers Rance to be his soulmate. He refers to Rance as "partner" and, while they get along really well, Rance usually tells him to keep quite because a talking sword is creepy and weird, and it's something that drives away many people. Like Rance, he's mostly motivated by a desire to smite evil and perverted thoughts. He claims that he prefered rough sex and that his favorite kind of woman is a naive westerner under the age of 20 and he likes virgins better.

He's often silent and obedient most of the time, although this is only with Rance since most of his wielders end up throwing him away due to being unable to put up with him. However, he seems to have a soft spot for Café Artul, another member of The Legendary Five, and is rather protective and caring with her in particular.

He has an abnormal lust for slicing and killing Dark Lords, going into short excited speeches about it if given the chance. His goal is to defeat the Dark Lords and become human again.

Abilities
Since Chaos, like Nikkou, is now nothing more than a talking sword, in order to fight the dark lords and the demon king, he needs a wielder. He's one of the only three swords that can neutralize the Invincibility Field and damage Dark Lords. Unlike the Hero Sword Escude, Chaos and Nikkou can temporarily shatter the invincibility field, rendering the Dark Lord vulnerable to any attack from other sources, rather than just piercing through said field.

Even without that, he is a powerful sword. He has the ability to gauge the power of enemies on the battlefield.

He can summon spiritual hands, a kind of aura he generates to interact with the world, although he doesn't do it too often, and when he does it's mostly for erotic purposes, but eitherway these hands are barely tangible and he can't really do much with them.

He can be wielded by anyone as long as they have a strong will, if the wielder of Chaos has a weaker ego than him, their mind would be overwritten and Chaos would be able to control them. This is the reason why Chaos is considered a "curse blade" and no-one wants to wield it, since legend says that anyone that wields it would be corrupted by Chaos.

When he was a human he was a famous thief and asassin that gave him the nickname of Chaos, his real name remains unknown. While his former levels were never revealed, he had Thief Lv2 and Short Sword Combat Lv1 skills.
