Appearance: Mouse-colored hair, wearing a black hood and outfit. The sleeves are rather oversized. A red mask covers one half of her face (which she sometimes removes). She wields a knife larger than an ordinary blade, with a sharpness comparable to a sword.
Diavel Star is a witch known by the alias “Treasure Hunter.”
She possesses the power of a treasure called Luciera, which can transform into a scythe-like weapon of tremendous might. She also carries a purple, thread-like substance that enables her to move at incredible speed (this purple thread is often used in battles against Snake Eye). In addition, she wields the power of another treasure named Silvia. Silvia allows her to extend wolf-like claws and hands from her body, and she can even crush objects with her teeth. (Since these treasures’ powers are last-resort abilities, she only uses them in emergencies.)

The red, eye-like core is extremely tough and unbreakable. When the Snake Eye Flame Dragon is defeated and vanishes, the red, eye-like core falls to the ground, from which the Snake Eye Flame Phosphorus (Snake Eyes Populus) emerges.
