The Hotel of Death was an eccentric establishment run by the mighty Anubis himself. Nestled in a realm between life and death, it catered to souls waiting for their final verdict.

Anubis was known for his meticulousness and fairness. Every soul had its rightful place, and no one ever slipped through the cracks. Until one peculiar case.

A young girl, seemingly no different from the rest, had checked into the hotel. Her name was Elara. She was quiet, kept to herself, and was always seen with a faint smile.

Elara was not like the other guests. She did not fear death, nor did she long for life. She merely existed, moving quietly through the hotel's eerie halls.

Despite her tranquility, Elara sparked curiosity. Anubis found himself intrigued by this girl, whose arrival date seemed to be lost in the records.

He delved into the archives of the hotel, determined to solve the mystery. Surely, every soul had its time, and Elara was no exception.

Days turned into weeks, and weeks into months. Anubis scoured through centuries of records, but Elara's arrival date remained elusive.

Finally, a realization struck Anubis. He found no record of Elara's arrival because there wasn't one. Elara was not a guest; she was an anomaly.

The mysterious girl was not a soul waiting for judgment. She was immortal. This revelation sent a shiver down Anubis's spine.

For the first time, Anubis was unsure of what to do. The Hotel of Death had never had a guest like Elara before.

He approached Elara, his eyes reflecting his newfound knowledge. The calm girl merely looked at him with her serene blue eyes and smiled.

"I wondered when you'd figure it out," she said, her voice as soft as a whisper. Anubis could only gaze at her in silent astonishment.

Elara explained her immortality, a curse bestowed upon her for reasons she did not know. She was bound to exist, neither dead nor alive.

The Hotel of Death, a place suspended between life and death, was the only place where she could find solace. Anubis listened, his eyes filled with empathy.

As time passed, Anubis and Elara formed an unlikely friendship. The immortal girl became a constant in the ever-changing landscape of the hotel.

Elara helped Anubis with the hotel, tending to lost souls with a kindness that warmed even the coldest hearts. Her presence was a beacon of hope.

The other guests, oblivious to Elara's immortality, found comfort in her presence. She was a friend, a confidante, and a guide to those in need.

Anubis found himself grateful for Elara's presence. She brought life to the Hotel of Death, a contradiction that only heightened its charm.

The Hotel of Death, once a place of finality, was now a place of existence. It was no longer just a stopover, but a home for the lost and immortal.

Elara and Anubis, the immortal girl and the god of death, continued to exist in this peculiar harmony, bringing comfort and companionship to those who needed it most.

The story of Elara and Anubis spread far and wide, their friendship becoming a tale of hope and perseverance. A tale that transcended the boundaries of life and death.

Elara's smile, once a mystery, was now a symbol of hope. Anubis's stern demeanor softened, his heart opened by the immortal girl's unwavering spirit.

In the end, the Hotel of Death became more than just a hotel. It became a sanctuary for the lost, a beacon for the weary, and a home for the immortal.

And at the heart of it all was a girl named Elara, an immortal soul whose existence brought life to a place of death, and a god named Anubis, who found friendship in the most unexpected places.

So the story of the Immortal Guest continues, echoing through the halls of the Hotel of Death, a testament to the enduring power of friendship and the eternal spirit of hope.
