It's been a year since Aoi started working at Kura, and now spring break is full of excitement: a hot springs trip with Kiyotaka and Akihito, a book club party, and more! But at the same time, she is struggling to decide whether to tell Kiyotaka how she feels about him. One day, an editor shows up at Kura under the pretense of doing an interview for a magazine. Then, in the middle of the night, the master forger Ensho steals a Shino tea bowl from right under Kiyotaka's nose. The next morning a written challenge from Ensho arrives—the mysteries continue in Volume 5 of Holmes in Kyoto!
