Puzzle Overview and Importance

This puzzle is a three-stage lockbox found in Classroom 2-1. Solving it is the only way to exit the room and continue your exploration of Ebisugaoka Middle School. The reward, the Second Floor Classroom Generic Key, is vital. It unlocks nearby classrooms, allowing you to find key items like the Fox Origami of Grievances, which is needed for the school locker puzzle. Therefore, mastering this puzzle is a critical step in Chapter 6.

Understanding the Clues: Rinko’s Letters

The solutions are derived from three letters written by Rinko, found within the classroom. Each round corresponds to a specific phrase:

• Round 1: “sweet and tart fruit”
• Round 2: “journal”
• Round 3: “sakura in full bloom”

On Story difficulty, these keywords are highlighted in your journal. On Hard and Lost in the Fog, they are not, forcing you to interpret the letters yourself. The symbols on the puzzle box (fruits, books, flowers) represent elements from these clues.

Story Difficulty Solution

• Round 1 (Sweet & Tart Fruit): Reveal the Cherry and Strawberry symbols.
• Round 2 (Journal): Reveal All Books symbols.
• Round 3 (Sakura in Full Bloom): Reveal the Sakura Blossom Branches symbol.

Hard Difficulty Solution

• Round 1: Reveal All Fruits symbols.
• Round 2: Reveal All Books symbols.
• Round 3: Reveal  Sakura Blossom Branches symbol.

Lost in the Fog Difficulty Solution

• Round 1: Reveal All Fruits on both sets of tiles.
• Round 2: Reveal All Books on both sets of tiles.
• Round 3: Reveal Sakura Blossom Branches across the tiles.

Puzzle Box Rewards and Progression

Successfully completing all three rounds will open the box. Inside, you will find the Second Floor Classroom Generic Key. A short cutscene will play by the windows, and the classroom door will unlock. With the key, you can now explore the other second-floor rooms. Your immediate next step should be to find the Fox Origami of Grievances in a nearby classroom to solve the locker puzzle and claim the Wolf Omamori and School Bag.

Tips for Solving on Hard Mode

Since the journal doesn’t highlight keywords, read Rinko’s letters carefully. For Round 1, “sweet and tart fruit” implies multiple fruits, hence “All Fruits.” For Round 2, “journal” and “filling up pages” suggests all writing-related symbols (“All Books”). For Round 3, “Sakura in full bloom”. If stuck, ensure you are sliding both the front and rear panels to find all required symbols.
