Starting From a Mysterious File

One day, the male student Nonomiya accidentally stumbles upon a notebook belonging to his schoolmate Youko Tsukimori. Inside the notebook lies a piece of paper titled Murder Recipe.

At first, he merely assumes it is a purely imaginative accident script. However, things quickly spin out of control when Youko Tsukimori's father suddenly passes away in an accident that matches the description identically.

From that moment on, Nonomiya is drawn into a journey to uncover the truth behind the mysterious girl and that strange piece of paper.

Battle of Wits Between Contrasting Personalities

The work focuses on exploring the profound psychological contrast between the two central characters. Nonomiya holds pessimistic views, feels weary of everyday life, and always chooses to hide within his inner world.

Conversely, Youko Tsukimori possesses a flawless appearance, exceptional beauty, and top-tier academic performance. Yet, hidden beneath that facade lies a calculating and cunning nature.

The relationship between the two evolves into a mental game filled with suspicion. Nonomiya tries to maintain a safe distance while simultaneously being strongly drawn to her peculiar charm.
