A floral disease that started because of the 2007 Arsenic Leak. According to reports the spreading of the toxic substance came from a nearby pesticide factory that failed to notice their sewage waste being washed to the nearby flower farms. This went unnoticed for 5 months from February to June until a female student was found dead by her classmates in the bathroom. She was seen growing flowers from her mouth with thin stems and thorns around her neck. A total of atleast 1,000 people have died due to disease. Early signs of this are troubling breathing, trouble eating, coughing, sleep apnea, blurry vision, and brain damage. Mode of transmission is pollen or smelling a flower. It takes 3 months for some sign to take place, and 5-6 months for a complete and brutal death by strangulation and brain death. Extreme cases could lead to skull explosion or bloody tears. Ina's core was examined by the ERD and he was found to have had massive doses for arsenic, but despite that, due to him being half-human, his body refused to die (Undertale reference). Ina was a rare case of someone living through the disease. His core was changed eventually, but the remnants like his flowery lungs, blurry vision, and the visible stems and thorns around his neck remained.
