However, as a result of the investigation, multiple pieces of evidence point to Hajime's guilt. There is a record of Hajime being near the staff room during the time the safe was opened. Hajime's fingerprints were detected on the paper bag that contained the student council funds. The paper bag containing the missing 100,000 yen was found in Hajime's bag. Immediately after the incident was discovered, it was revealed that the President, Vice President, and Treasurer were the ones managing the keys and the safe.
