Once you finish gathering all four of your partners together, you will gain access to a new part of the school grounds. Sadly, this area contains some of the hardest puzzles in the game. Below is a walkthrough of the Memorial Garden puzzle and how to solve it.
Once you get into the garden, go straight, and follow the path down to the monument. Once there, speak with the girl in front of the monument. You’ll learn that she has the key. You will now want to examine the side of the monument and write down the missing student’s ID, 020211010.
You should now head back to the first-year building. On the first floor, you will find a classroom with a note and flowers on a desk. These are Rosemary. After seeing the note, head to the computer lab on the third floor.
You will want to type in the missing student’s ID, 020211010, and then type in Rosemary for the password. This will give you the student’s name. Head back to the memorial garden and tell the confused girl to get the key to the gate and reach the first ideal.
