Unaired episode included with the 7th volume of the BD/DVD release of Kobayashi-san Chi no Maid Dragon.

When Shoutarou Tatewaki first meets Sakurako Kujou, he knows his life will never be the same. Initially believing her to be responsible for a disappearance in the neighborhood, he later learns of her true talent: analyzing bone specimens. Sakurako has quite the collection of reconstructed animal bones, but she wishes she had more of the human variety, much to the chagrin of those around her. Soon, Shoutarou begins accompanying the eccentric osteologist on the many different unsolved cases she comes across—usually in the form of decomposing bodies. But with so many incidents happening around them, could there be a larger mystery at work in their lives? Sakurako-san no Ashimoto ni wa Shitai ga Umatteiru is a story of two unlikely partners, each showing in their own way that bones can tell how one died, but only people can tell how they lived.

With the tumultuous cultural festival behind him, Masamune Makabe continues his efforts to carry out his revenge: to make the "Cruel Princess" Aki Adagaki deeply fall for him and then immediately dump her. As his class is going on a trip to Paris, widely known as the City of Love, Masamune has the perfect opportunity to get even for his childhood heartbreak. Before Masamune can impress Aki, the two meet Muriel Besson, a French high school otaku who aspires to create a romantic comedy manga series. Muriel believes Masamune is the ideal model for the protagonist and asks for his help. The boy reluctantly agrees, dragging Aki along to provide inspiration for the love interest's character. But to do so, the two must show Muriel what Japanese love is like. To make matters more complicated, Kanetsugu Gasou is masquerading as Aki's childhood friend, Masamune, to trick and use her. With mix-ups and love rivals galore, Masamune's revenge is proving to be quite the difficult task.
