HERO, 'Horimiya' Mastermind, Unveils Gripping Psychological Thriller 'Koe no Furu Heya'

HERO, the visionary creator behind the globally adored romantic saga Horimiya, is poised to embark on a thrilling new chapter with the launch of his latest manga, Koe no Furu Heya (The Room of Fallen Voices). This highly anticipated series, a significant pivot in genre, officially debuted on July 28, 2025, in a compelling collaboration with the talented artist Takahashi Tsutsuji. Serialized exclusively in Shogakukan's renowned Weekly Big Comic Spirits, Koe no Furu Heya promises to immerse readers in a gripping narrative of suspense and psychological drama, demonstrating HERO's remarkable versatility and his continued evolution as a master storyteller.

Diverging sharply from the warm, slice-of-life charm that defined the high school romance of Horimiya, this new work introduces a chilling premise. The story centers on an illustrator protagonist whose life takes an ominous turn upon receiving a cryptic, unsettling message from a former high school classmate. This alarming communication serves as a dire warning about a lurking stalker, inexorably drawing the protagonist into a complex and dangerous web of unresolved past secrets and immediate, palpable threats. Readers can anticipate an eerie, deeply profound exploration of the human psyche, a narrative that, while a stark contrast to HERO's earlier successes, promises to retain the emotional depth and relatable character dynamics that have long endeared his works to millions.

This bold new direction follows his recent exploration into different themes with the three-chapter story, Terasu Hikari wa Ani no Omokage, which was published in June 2024.

The enduring legacy of Horimiya, meticulously illustrated by Daisuke Hagiwara, captivated audiences for a decade, culminating in 17 volumes upon its conclusion in 2021. Its immense critical and commercial success paved the way for multiple highly acclaimed anime adaptations, including the beloved 2021 TV series and the equally popular 2023 follow-up, Horimiya: The Missing Pieces, both widely accessible to international audiences through streaming platforms like Funimation and Crunchyroll.

The premiere of Koe no Furu Heya arrives amidst a fervent anticipation from a global fanbase, all eager to witness how HERO's distinctive narrative voice will powerfully resonate within the thrilling, uncharted territory of a suspense-driven plot. This new series stands as a testament to his creative courage, promising to be another compelling addition to his illustrious bibliography and solidifying his reputation as an artist unafraid to explore new narrative frontiers.
