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.
So, you have mayonnaise 
coming out of your eyes?
يخرج المايونيز من عينيك إذًا؟
Aus deinen Augen kommen
also Tränen aus Mayonnaise?
Entonces,
¿te sale mayonesa por los ojos?
Entonces,
¿te sale mayonesa por los ojos?
De la mayonnaise
te sort des yeux, tu dis ?
Quindi, ti esce la maionese dagli occhi?
Então, está saindo maionese
dos seus olhos?
Говоришь, у тебя из глаз течёт майонез?
