五年B班事件簿 - The Grade 5B Case Files

Open the notebook and explore seemingly ordinary yet mysterious incidents together with two girls!

Watsonia, a student in Grade 5, Class B at Seashell Elementary School, buys a notebook at a stationery store. At the time, she has no idea what she wants to write in it—she simply finds the cover cute and decides to buy it. This notebook becomes the starting point that brings Watsonia and her classmate Holmlyn together as a team of two, investigating and deducing unusual incidents hidden within daily school life.

To others, these incidents may seem like something trivial caused by children. But for Holmlyn and Watsonia, each one of them is a difficult “case” .

As the mysteries unfold one by one, a larger picture of life in school gradually emerges.With Holmlyn, who is a detailed-oriented and action-driven person, and Watsonia acting as her “assistant” who carefully records every clue, the two work together to uncover the truth behind each case. Along the way, classmates, teachers, and students from other grades all make their appearances, forming a fair-play mystery story set within the school.

As the player, you will collect clues, conduct investigations, think things through, and make correct deductions alongside them. Watsonia records all clues in her notebook—if you ever feel lost, try opening it and taking another look.
