Polly

Polly grew up in the hospital where she was abandoned after being born. The kind head nurse took pity on the innocent child, adopted her and placed her in the hospital's dormitory.

Growing up in the hospital, Polly saw injuries and deaths, recoveries and new lives being born all throughout her childhood. She soon understood how lucky she was to be adopted. Having grown up with the kind and responsible doctors and nurses, she felt very grateful.

Ever since Polly started to discover things, her dream never changed - to become a doctor that saves people's lives.

But soon she found that she couldn't save everyone.

Polly's hospital was overcrowded by people because of a strange disease that kept people sleeping. Although the hospital often had patients that passed away, it had never had such a huge and inescapable haze of death.

The head nurse ran around like a female warrior in the hospital. Seeing her, Polly felt like she was a lighthouse that never went out, and always had the power to fight on. So when the head nurse also collapsed, Polly felt despair for the first time. However, having been raised by a tough head nurse, she soon woke up and realized that complaints couldn't solve anything.

Not only for the head nurse, but also for all the patients, she would fight until she collapsed herself.

The death of the head nurse strengthened Polly's determination to become a doctor, and she hoped to inherit the head nurse's spirit.

After working and studying at the same time, Polly finally got an offer from the best medical school in the world with her excellent grades. It was there that she met Lily. After experiencing the Nightmare Professor incident with Lily at school, Lily and Polly became best friends. Both of them were willing to serve Radiants who get hurt in battle against Nightmares.

Later, they were recruited by SEED together, but the rigorous SEED always made Polly feel out of place.

At this time, a man named Berial came to her.

As a pioneer of modern medical science, Nightingale believed that besides treatment, people must also pay attention to patients' physical conditions, living environment, mental state, etc.

During her studies, she found that there was another "spiritual world", like the dreams of patients. The states of patients in dreams also affected their states in reality. So she began to look for ways to cure patients in that world. Eventually she became a Radiant and was able to heal others in the Dream.

She began her life as a Radiant and discovered a way to save wounded in the Dream, but after her death, her spirit turned into a Lens and disappeared with her knowledge.

In the city where Polly lived, there was a strange infectious disease. No matter how doctors tried to cure it, it didn't get better. Eventually, the patients died in their sleep. Some even claimed that it was a curse. The head nurse who adopted Polly also got infected while taking care of patients. Polly searched around for a cure, but nothing was found.

Polly refused to give up, and began reading every book she could lay her hands on, even the most shabby and unremarkable ones. One night, she was so tired and fell asleep. She dreamed of another world and met the head nurse who was being consumed by a Nightmare.

Polly's anger and sadness peaked at this moment, turning it into a huge force that filled her body.
