People become afflicted by "mysterious diseases" when their hearts and minds are affected by "the mysterious."
Koto, a girl who produces mayonnaise from her eyes, visits Dr. Ramune, who specializes in these diseases that can't be explained by modern medicine.
She was brought to the clinic by Ramune's apprentice Kuro.
Koto explains that she also cries condiments other than mayonnaise, and Ramune offers her a mysterious treatment.
Well, mysterious diseases are 
still considered occult.
.في الواقع، لا تزال الأمراض الغامضة تُعتبر مبهمة
Verständlich. Mysteriöse Krankheiten
werden immer noch als Humbug abgetan.
Claro, el público sabe poco
sobre las dolencias extrañas.
Claro, la gente sabe poco
sobre las dolencias extrañas.
Normal, les maladies mystérieuses
sont vues comme une science occulte.
Beh, le malattie misteriose sono ancora considerate
 nella categoria dell'occulto.
Bom, a incognose ainda é
considerada coisa de ocultismo.
Ну, мистические болезни до сих пор
считаются чем-то оккультным.
