Lancelot du Lac

At one time, Lancelot was an ally or Subordinate God to the Heretic God known as the King of the End, the most powerful known God of Steel.

[Spoiler] Lancelot always wears a white steel knight's armor, but she's in fact a beautiful Caucasian girl with honey-colored hair and sky-blue eye. She was described as in her late teens. She has a tall, slim build with an exquisite face like an angel's, displaying all-surpassing purity (by Godou). [/Spoiler]

[Spoiler] She formed a plan to form a pact with Godou to fight the Black Prince. She hungers to fight Godou in a duel to the point where she erased her own memory just to get close into him (eventually reminded of her true nature when Godou said her name). [/Spoiler]
