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 bet you're a quack who will demand 
a huge amount of money!
!أراهن أنّك دجّال سيطلب الكثير من المال
und verlangen Geld?
Das ist doch reiner Betrug!
¡Eres un patán
que quiere sacarme dinero!
¡Eres un patán
que quiere sacarme dinero!
Vous essayez
de me soutirer de l’argent ?
Sarai solo un ciarlatano che vuole spillare soldi!
Aposto que você é um charlatão
querendo dinheiro!
Шарлатан, небось, и
затребуешь кучу денег!
