Story Introduction

Kojiro Kashima lives a quiet life in a rural town with his mother Sakiko and younger sister Izumi. When Izumi becomes a shut-in, the family relocates to the city. At his new school, Kojiro unexpectedly reunites with Natsuki Takino and Yuka Miyama—girls he met during a beach trip the previous summer. However, Natsuki greets him with undisguised hostility, constantly blaming him for something he can’t recall. Before he can get answers, his phone receives an email from someone claiming to be “Anonymous.”

“I know your secret.”

Messages arrive daily. Anonymous knows everything but refuses to reveal it, seemingly enjoying Kojiro’s frustration. Yet Kojiro becomes convinced that a hidden “secret” exists from that summer—something connected to his meeting with Natsuki and Yuka, and the incident that drove Izumi to isolation.

Determined to uncover the truth, Kojiro pursues the mystery. He senses this path will bring him nothing but regret. But he has already gone too far.

A psychological thriller adventure that unfolds from a single mobile message. Directed and written by Kichikujin Tamuu (known for “The Season You Were Here” and the Muv-Luv series), with character art by Propaganda Toru Shin. Experience an intricately woven romance drama with realistic horror born from distorted truths, told through multiple character perspectives.
