For the past two years, the manga industry has been whispering a name. That name is The Summer Hikaru Died (Hikaru ga Shinda Natsu). Written and illustrated by Mokumokuren, this horror-mystery series has captivated readers with its unsettling atmosphere, delicate emotional core, and truly terrifying premise.
