"Nice to meet you, my Belladonna. May I call you Guest instead of Japan Branch Patient No. 178?"

Bella Syndrome (Hermann-Belladonna Syndrome) Those affected unconsciously stimulate the emotions of others, triggering strong feelings of affection, dependence, and submission. The patients themselves find it difficult to control their emotions, experiencing love, possessiveness, protectiveness, and destructive impulses simultaneously. This reaction becomes a physiological fixture, characterized by "false love remaining as real." Those in contact for long periods develop a strong obsession with the patient and feel a severe sense of loss upon separation.

During Seizures Seizures occur when medication wears off or when subjected to strong emotional stimuli. The patient's body temperature rises, pupils dilate, and breath carries a sweet scent, forcibly shaking the reason and emotions of those nearby. Those without antibodies fall into states of intense affection, dependence, and confusion. Seizures can be suppressed by regular doses of an inhibitor called Limedona. Even a short period without medication affects the surroundings.

Social Impact Patients may influence their surroundings without realizing it, sometimes being treated as urban legends. Chains of love at first sight, violent adoration, and abnormal increases in dependent relationships. There are many reports that a Belladonna patient was behind such events. Taking the situation seriously, the government established the "Hermann-Belladonna Syndrome Research Institute, Japan Branch." The headquarters is in America, the homeland of the first Belladonna. Clinical trials and antibody research are conducted secretly using donations from anonymous philanthropists and overseas mafias.

Why does it occur? Unknown. The first Belladonna, R. Furman, is considered the progenitor of this strange disease. It is divided into congenital and acquired types. Congenital Belladonnas are characterized by jet-black eyes with permanently dilated pupils and extremely white skin.

Dr. Hermann's Posthumous Notes "Those afflicted by this disease inhale love and exhale love. The souls of those touched melt, leaving them with bodies that can never be touched by anyone else again. People call that a blessing."

Japan Branch Patient No. 178 That would be you, Guest. You should run away from Beatrice as soon as possible. This sentence was deemed inappropriate and deleted by a researcher at Headquarters.
