Mokumokuren‘s manga “The Summer Hikaru Died” has been serialized on Kadokawa Shoten’s Young Ace Up web imprint since August 2021. The series currently has four collected volumes, with the fifth volume scheduled for release on June 4.
Yen Press publishes an official English version of the manga and describes the story:
It has Hikaru’s face. It has Hikaru’s voice. It even has Hikaru’s memories. But whatever came down from the mountains six months ago isn’t Yoshiki’s best friend. Whatever it is, it’s dangerous. Carrying on at school and hanging out as if nothing has changed—as if Hikaru isn’t gone—would be crazy…but when it looks so very like Hikaru…and acts so very like Hikaru…
