Morgawse

"I refuse."

- Morgawse typical response and catchphrase Morgawse (モーゴース, Moogoosu) is a member of the Royal Family of King Arthur, being known as the youngest sibling, but is a legendary figure known as Arthur's only equal, who died soon after giving birth to her only child, Sir Gawain. Morgawse was known as the Odd Knight (変騎士, Henkishi), due to being the first knight who wore no proper armor and dual wielded a pair of swords, one being a legendary sword given to her by Nimue, while the other is a man-made crafted sword.

Known most infamously as the Thousand Man Slayer (千故殺, Senko Hitokiri), Morgawse was an accomplished swordsman and warrior who managed to surpass all expecations with her insurmountable willpower, despite being expected to die fairly young and never amount to anything as arguably the weakest sibling with no special powers or potential.

Trivia

 * Morgawse is obviously based off Morgawse of Arthurian legend, with several tweaks here and there, the most prominent being the fact she is a knight who fights.
 * In addition, Rhongomyniad is a spear, not a sword, that was wielded by Arthur, while Seure is a less known sword that Lancelot once wielded.
