Crystal
-----
In front of us, the boss of the dungeon emerged… It was a gigantic Zombie Dragon, powerful enough to even rival the strength of Lucifer and Brunhild combined. The Zombie Dragon's body was covered on hard and colorful scales, resembling dark blue, black, red, and purple crystals growing all over the monster's body.
The Dragon's skull could be seen, and it lacked eyes, the crevices of its skull flashing with phantasmal blue flames, filled with feelings of resentment, hate, anger, and sorrow… I could feel the Dragon's pain.
But when Brunhild and Lucifer recognized the Dragon's appearance, everything changed. We fell into silence, as we glanced at the scene. I couldn't recognize her, but she was named Crystal.
…Or well, that was the name she had when she was alive.
"Crystal…?!" Lucifer cried. His entire body was suddenly paralyzed, he couldn't move an inch. His eyes seemed filled with despair, as he started crying.
