Emilia and Ram's Very Bumpy Master-Servant Relationship

Emilia and Ram's Very Bumpy Master-Servant Relationship (エミリアとラムの主従凸凸凹凹) is a Melonbooks shop exclusive limited edition short story that came with Volume 9. This was later adapted and included in the Re:Zero Ootsuka Shinichirou Art Works Re:BOX.

Summary
During their singing lessons in a soundproof room, Ram notices that Emilia is not performing well at all today and asks what is disturbing her. Emilia mentions that she wishes to find a way to properly reward Subaru for all he has done and asks from Ram what should she do, since she doesn't believe the rewards he asks are enough. The girls start gossiping about from where he is and what would be best to give him as a reward. The next day, Ram brings Subaru to the dinner table and Emilia presents steamed potatoes made with mayonnaise to him, a dish she proudly announces as the efforts of herself and Ram. This is much to Ram's annoyance, as she didn't want Emilia to reveal she helped at all. The story ends with Rem speaking with Ram about this event and saying she was a bit jealous of being left out. After Rem leaves, Ram angrily comments while grinding her teeth, "Barusu... You are unforgivable!!!"
