Two of the clues are mechanisms located on both sides of the building, and then a flower pot and a basket in front of the house.

In the initial investigation with Yelan, she will provide you with a Forensic Imaging Device to use during your search. Make sure to equip it from your inventory before speaking with Yelan to begin each investigation.

The purpose of this event is to locate clues in each investigation location using the Forensic Imaging Device that Yelan provided. To accomplish this, simply use the device to scan for unusual items in every spot.
Keep in mind that you may need to scan the object from specific angles before the small circle appears and records the clue.

Always check the case records because they indicate the number of clues needed as well as the initial appearance of the site before it has been tampered with. You may then compare the location from the record to the current one to see what new things are present.

This event's quest also features Yelan's new 4-star outfit, Tranquil Banquet, which fits in well with the investigation theme of the event!
