In the world-famous legends of King Arthur, Sir Gawain of the Knights of the Round Table was famed for martial prowess wholly inferior to none, not even Lancelot, known as the strongest Knight of the Round Table.
His swordsmanship was superb and his martial strength exceptional. He had received the sun's favor and a saint's blessing, rendering him invincible beneath the noon sun. Even Lancelot, hailed as the strongest Knight of the Round Table, had to drag a battle out until sunset for a chance to defeat him.
Gawain had once, like King Arthur, received a Holy Sword bestowed by the Lady of the Lake.
It was a Holy Sword identical to the King's Sword wielded by King Arthur—a sister blade to the King's Sword. Corresponding to King Arthur's Holy Sword, which was blessed by the moon, it possessed the sun's favor. Its hilt even contained a pseudo-sun, making it a genuine sword of the solar disk.
This was Sir Gawain's Sun Holy Sword—Caliburn.
The demonic sword wielded by Bagster was a replica of Sir Gawain's Holy Sword, fashioned by imitating her own "antler." It was known as Burning Antler—Fairy Sword Caliburn.

It had constantly suppressed the growth of Bagster's Spirit Origin. Once removed, all of Bagster's reason would vanish, and she would undergo true atavism, becoming an active A-Ray. Her body and power would continually expand under the planet's empowerment, until she became a monster in the truest sense—one casual strike sufficient to destroy the earth.
The Fairy Sword Caliburn replicated from such an "antler" might not have matched the true Sun Holy Sword Caliburn in rank, but in terms of sheer scale of power, it
