Golden Darkness by Arisa, sweet as usual. Her costume is exactly same with the original anime but(i don't know why) her contact lenses should be maroon(check by yourself^^). her hairpieces need more craft attention.
She is a dispassionate, withdrawn assassin, Golden Darkness is hired by one of Lala's arranged suitors, Lacospo to kill Rito, until she breaks the contract, noting the true nature behind her target.
Golden Darkness' physical abilities are exponentially stronger than a human's. She carries a unique ability to turn her body parts into various objects through use of nano machines circulating her body, ranging from swords to dragon heads. Unfortunately, excessive use becomes a hazard to her health.
