The village of Kurohana was quiet under the silver moon. Aika, a simple girl who lived with her grandmother, always felt that she was different from others.
One night while walking near the forest shrine, she heard a strange whisper.
"Find me…"
Inside the old shrine, she discovered a mysterious black sword stuck in a stone.
When she touched it, the sword released dark energy and a voice echoed in her mind.
"You are the Shadow Guardian."
At that moment, Aika's peaceful life ended.
