How exactly did Hikaru die on the mountain?

How exactly did Hikaru die on the mountain? This haunting question lies at the heart of Mokumokuren's psychological horror manga, though the exact details remain deliberately ambiguous throughout most of the series.

The Mountain Incident

Hikaru's death occurs during a mountain expedition before the main story begins. While exploring the mountainous terrain, Hikaru encounters something supernatural and malevolent that ultimately claims his life. The manga suggests that whatever killed Hikaru was connected to the ancient, otherworldly entities that inhabit the mountain's depths.

What Replaced Him

The most chilling aspect isn't just Hikaru's death, but what happened afterward. The entity that killed him took over his body, perfectly mimicking his appearance and mannerisms. This imposter returns to town, fooling everyone—including Hikaru's best friend Yoshiki—into believing he survived the mountain trip unharmed.

Clues Throughout the Story

The manga drops subtle hints about the true nature of Hikaru's death:

- Strange behaviors and knowledge the real Hikaru wouldn't possess

- Unnatural physical abilities and reactions

- Moments when the facade briefly slips, revealing something inhuman underneath

- References to the mountain's dark history and supernatural inhabitants

The Psychological Horror Element

What makes Hikaru's death particularly disturbing is how seamlessly the entity replaces him. The horror comes not from graphic violence, but from the gradual realization that the beloved friend everyone mourns has been gone all along, replaced by something wearing his face.

The ambiguity surrounding the exact circumstances of Hikaru's death adds to the story's unsettling atmosphere. For readers seeking more details about the supernatural elements and the entity's true nature, exploring the manga's later chapters reveals additional layers to this tragic mystery.
