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.
Koto, why do you keep saying 
things to upset me these days?
كوتو، لمَ تواصلين في قول كلامٍ يغيضني هذه الأيّام؟
Warum bereitest du mir in
letzter Zeit nichts als Ärger, Koto?
Koto, ¿por qué últimamente
no dejas de decir cosas que me irritan?
Koto, ¿por qué últimamente
no dejas de decir cosas que me irritan?
Koto !
Koto, perché continui a dire cose 
che mi fanno arrabbiare?
Koto, por que você diz coisas
que me trarão problemas?
Кото, почему ты продолжаешь
говорить о том, что меня расстраивает?
