Haruna is found unconscious and taken to the hospital. While her parents are arguing, Haruna sneaks out of the hospital after remembering that the man threatened to kill Ran if she did not deliver the "Rainbow Child" to him. Elsewhere, Conan and Heiji learn that Haruna was only able to read part of the letter causing her to read "Kinosaki Hot Spring Station" as "Mountain Station" and thus explains why she was searching for her mother at the mountain. After a long search, Conan and his companions are able to find Haruna at her aunt's home and capture the mysterious man. The man is revealed to be Yumoto who reveals a man paid him to take the Rainbow Child back from Haruna. Conan reveals that the mysterious man in Genta's picture is the one who ordered Yumoto to commit the crime and reveals the culprit to be the Takeshi Kamachi, the president of the museum Haruna stole from. As evidence, Conan reveals that the culprit received a stain from Genta's crab flavored ice-cream, the same stain found on Kamachi. Conan reveals that Kamachi wanted Haruna to steal the "Rainbow Child" to complete the "Rainbow" set which consists of a sculpture of a mother holding the "Rainbow Child". Kamachi confesses to the plan and reveals he needed the money to pay off his debts. Later on, Haruna is reunited with her mother and father and with Ran's persuasion, reunited as a family.
