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.

Perhaps seeing himself as an Undead didn't bother him, but when he saw the decaying and groaning body of the woman he loved the most… It must the most heartbreaking thing in the world.

"This… I knew something was up… This dungeon, this accursed dungeon!" Cried Brunhild, her flames flickering as she hit the ground in fury and frustration.

"Papa?!" Nyx wondered, flying towards her father, who was in tears.

Nyx looked back at the giant dragon, afraid of the beast's enormous strength, and its slow steps, as it made its way towards us… This beast was her mother.

Maria felt taken aback by this revelation, as she didn't even knew what she could do to help everyone now. The Dungeon's Last Boss was the reanimated corpse of Lucifer's wife. Maria couldn't control it either, no matter how hard she tried, and every time she attempted to glance at the undead soul, she would sense this feeling of dread like nothing she had felt before… Crystal's soul was either completely consumed by this darkness or wasn't even there to begin with.

Maria couldn't tell until she clashed against the Undead Dragon and were to find out by herself… But things were only getting worse, the Dragon's powers weren't merely intimidation, it spread a powerful Domain that enhanced its stats and lowered those of its foes, it slowly approached at the same time, as if it was enjoying the despair of its victims.

"Crystal…"

Lucifer seemed to be completely frozen. As he glanced at the decaying body of his loved one, he despaired. This wasn't how he wanted it to be… This wasn't how he thought it would happen either. He didn't wanted to meet her again like this.

He had imagined her body had been buried in the mountain, and that was the end of it. He never thought for a moment that something like this could had happened to her… This Dungeon had the capacity of devouring the mountain's resources and energy, it even meant absorbing the corpses of anything buried in there.

The amount of Undead they fought was so large because they weren't simply the bodies of old dwarves that visited this dungeon, but also of other people that had merely been buried in the mountain long ago… the same happened for Lucifer.

Seeing his former wife like this made him feel completely despaired. It wasn't just because of the horrifying appearance her beautiful wife's body had now, but also that her very being… it was filled with feelings of resentment, anger, despair, and suffering.

He could sense within her an incredible feeling of despair, like nothing else. The worst was that Maria couldn't do anything for her… Crystal couldn't be controlled by Maria's powers, and the only way to defeat her was by slaying her.

Killing the one he loved the most… He couldn't even imagine himself doing something so cruel. Despite the calling of Maria and Nyx, and everyone else with their Party, Lucifer seemed incapable of hearing anything but his own thoughts.

Images of his life flashed through his mind, as he felt an immense pain all around his soul and his head. The memories he thought he had lost slowly began to resurface one after the other after he saw his former wife's reanimated body.

The first time he meet her was when he was merely a young Dragon, back in the past, thousands of years ago, perhaps. He was youthful and energetic, he was always going into hunts into the wilderness, fighting monsters and slowly growing stronger.

Because of this, he always came back covered on wounds. Lucifer was an orphan dragon whose father and mother he never met. His egg was left inside a mountain and he hatched with the help of his big sister, a dragon a few years older than him that was always inside the cave with him.

She cared for him and helped him grow in his smallest of forms. However, as he grew older, he wanted independence as he became rowdier and wilder, so he ended going off to another cave, to live alone.

His big sister wanted to take care of him forever… but she knew he had to get to live his own life as well. Ultimately the two departed, although she often came to visit him once or twice a week, always bringing him company so he wouldn't feel so lonely.

But even then, he was most of the time alone. He enjoyed his loneliness though, although his family seems to have grown away from the larger tribes of dragons, so he was unable to socialize with them. His sister was slightly the same, more connected with nature, she merely hunted, ate, and slept.

Until one day, when Lucifer suddenly stumble upon a scene when he was looking for something to hunt in the Mountain's Forests. A smaller, crystal-covered dragon was fighting desperately against a fierce wyvern, and she seemed to be losing despite her hard defenses.

"ROOOAAR!"

"Uggh! Get off me you beast! Nnnggh…! Why is a wyvern this strong?! I won't be able to get back home with something for my siblings to eat like this!"

She fiercely fought against the Wyvern, a powerful B Rank monster twice as big as her, who was fiercely slashing and biting her body while bathing her on blazing breath.

Lucifer quickly arrived, emerging from the bushes and jumping over the wyvern, his powerful bite quickly tore through the monster's scales and then bit through the wyvern's neck bone, cracking it.

CRACK!

"GRYYAARRRGH!"

The Giant Wyvern fell into the ground, dead by the might of the young Lucifer. His wound-covered body surprised Crystal more than his sneaky attack.

"A-Ah! Another dragon…" She said, looking at him while still on the floor.

"Don't fight the things you can't beat." Lucifer said coldly, grabbing the wyvern by the neck and walking away.

That moment, Lucifer simply thought he would never meet her again.

Yet…

"W-Wait, please!"

She followed him.
