Inoue's bratty little cousin Yuuki is visiting. She's trying to cater to him by cooking his favorite breakfast (fried eggs) every morning, but he complains about the awful taste every time! Amami vows to help Inoue cook the best eggs ever, but after consulting with a nearby ghost, she learns that maybe Yuuki wants something more than just better flavor?

Amami meets the ghost of a young girl who keeps repeating a mysterious nonsense word: "Morya." No longer able to recall her life or how she died, the roll-call samurai and Amami worry she may simply fade away.
