True "Knights Glow"

The proud sword of Platina of the Divine Knights, beloved blade that cut so much evil. The shining blade was improved by a high-ranking sorcerer, who made it sharp and lethal, on the condition of the pureness and nobility of its bearer. They even say that when its possessor loses pride as a knight, the blade will decay as well. However, its effulgence has not been lost until now, and it continues to irradiate solemn light, proving that she who bears it is worth of her acclaim as a true knight.
