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.
I've also cried ketchup, sauce, 
ponzu, and noodle soup base.
كما أنّني بكيتُ الكاتشب والصّلصة 
.والبونزو وأساس حساء المعكرونة
Ich weine zum Beispiel
auch Ketchup, Soße,
También he llorado kétchup,
ponzu y caldo para fideos.
También he llorado kétchup,
ponzu y caldo para fideos.
Comme du ketchup, de la sauce,
Ho pianto ketchup, sugo,
 salsa ponzu e brodo.
Já saiu ketchup, molhos,
ponzu e até mentsuyu.
Я плакала кетчупом, пондзу
и соусом менцую.
