The "Marshmaro" characters are visible to us, but not to the people in the BonKoi world. They come in various forms, with various personalities. The scripts call them "Maro (type)." In this episode, Sayuri, Ryou, Mitsuki, Gilbert, and Yoshinosuke have been taken over by the Marshmaros. Enjoy a BonKoi that's a bit different from the usual!
with moles under their eyes are quick to cry, maro.
شامة تحت أعينهم هم سريعو البكاء-مارو
mit Leberflecken unter den Augen
schnell weinen, maro.
con lunares bajo sus ojos 
están listos para llorar.
con lunares bajo los ojos 
están listos para llorar.
est signe d’un pleurnicheur,
d’après maman, mallow.
com pintas debaixo 
dos olhos choram fácil.
