In The Summer Hikaru Died, the story revolves around a friendship that seems simple on the surface, but gradually becomes unsettling.
Yoshiki Tsujinaka continues his daily life alongside his best friend, clinging to the shared routine in the village. Hikaru Indo remains by his side, acting as always, even though there is something about him that no longer belongs entirely to the human.
Between them, the everyday begins to distort, and what was a childhood friendship turns into something difficult to name.
