Magic Sword, Zilinilam.
This was one of the four swords owned by a hero called the "Black Knight" among the thirteen heroes who ended the Demonic Chaos 200 years ago.
Legend has it that the "Black Knight" was a hybrid of human and demon, carrying four pitch-black swords: Zilinilam, which could release dark energy; the Decaying Sword Kurokdarbal, whose wounds couldn't heal; the Mortal Sword Shifez, lethal from a mere scratch; and the Evil Sword Xumilis, concealing unknown special powers.
These four pitch-black swords scattered across the world, their whereabouts unknown, gradually became the stuff of legend, desired by countless people without knowing if they truly existed.
However, Lakyus's emergence turned this legend into reality.
Because one of those four pitch-black swords, the one that could release dark energy—the Magic Sword Zilinilam, is now in her hands.
Indeed.
