Toyokawa Sakiko, with no memory of her past, awoke in a sewer in a back alley, the sort found everywhere. All she had with her was a suitcase [piano] and a cream-green-haired girl who seemed just as lost. This wasn't a stage for girls to enjoy themselves, but a place where all the city's filth flowed together. Fortunately, Sakiko survived and became a Grade 9 Fixer. Just three months after her life had finally gotten back on track, the event that swept across the entire city took place: the Seed of Light was released, and White Night and Dark Day began.
"Doctor, yes, I've been seeing things lately, and I've had symptoms like a loss of appetite. Insomnia? Well, I hardly need to sleep at all, desuwa."
"Your thoughts about the future? Your usual emotional ups and downs? Why are you asking about those? Are they related to my illness?"
The woman in a white coat, with brown hair tied in a high ponytail, nodded. Her smile never faded.
"It's obvious. You're ill."
"Toyokawa Sakiko, you have a City sickness."
