Sachi Sakurai discovered a bad habit of his grandfather Kazuya Sakurai: he likes to collect photos.

In fact, it is not brain-burning. The puzzle is similar to Turtle Soup. It can only be regarded as slightly suspenseful because certain conditions are deliberately hidden.
The main line of the story is that the protagonist group goes to a certain mountain to find clues to solve the mystery. This is actually a small game played by the protagonist group, just a joke.
The clues are arranged manually and there are no dangerous links.
The main clues are in Section 5 [Clue]. The answer to the mystery is in the last section [End].
