The Summer Hikaru Died episode 8 recap

Yoshiki witnessed what at first looked like a mannequin in the school courtyard. But the horror quickly escalated when it was revealed to be a real man who was seemingly deranged and compelled by a supernatural force. And to add to the disturbing scene, he slits his throat before anyone could make sense of the scene.
The mystery deepened when the episode highlighted Matsuura’s daughter recalling her deceased sister. There was a strong suggestion that the sister may have been killed or sacrificed on the mountain as part of these rituals.
A flashback also showed Takeda, sweating nervously, as though he had either witnessed or even taken part in something horrific. These hints suggest that the village elders carry dark secrets about what truly happened in the past, and why Nonuki was sealed away.
Meanwhile, Hikaru’s weakening condition became increasingly apparent. Ever since giving Yoshiki a part of himself, he has been more vulnerable to attacks from the impurities. A tense moment reinforced this when Yoshiki had to protect Hikaru from another monstrous apparition, highlighting their reversed roles: the human now shields the inhuman.
Their bond continues to evolve in unsettling ways, with Yoshiki even declaring his willingness to bear Hikaru’s sins alongside him, no matter how heavy.
The episode closed on another chilling note, with Yoshiki and Hikaru realizing that the map of the villages forms the shape of a body. If true, the seal on Nonuki may literally be tied to the land itself, with Kubitachi, the “neck”, holding the most significant connection.
What to expect from episode 9 (Speculation)

Episode 9 is expected to dive deeper into the ghostly apparition that nearly killed Hikaru and Yoshiki. Since Hikaru failed to consume it, the anime may reveal his declining strength and the consequences of giving Yoshiki a piece of himself earlier in the story. This raises questions: has Hikaru weakened himself beyond repair? And does Yoshiki now carry a piece of Nonuki-sama’s power?
Fans are also hoping episode 9 of The Summer Hikaru Died will expand on Kubitachi’s gruesome history. Was the village truly performing human sacrifices? Was Nonuki-sama a benevolent god corrupted by desperate rituals?
The recurring imagery of detached heads, necks, and sacrifices strongly suggests that Kubitachi’s villagers once dismembered people in order to appease or seal away Nonuki-sama. This episode may also bring Tanaka further into the spotlight.
Fan reaction to Episode 8

Episode 8 of The Summer Hikaru Died was one of the most unsettling yet fascinating entries so far. Many fans initially mistook the naked man in the schoolyard for a mannequin, only to realize in horror that he was a real person possessed and driven to slit his own throat.
That scene alone left viewers traumatized, but the deeper revelations about Kubitachi and Nonuki-sama have pushed the mystery to new heights. Hikaru weakening after giving Yoshiki part of himself has flipped their dynamic, with Yoshiki now needing to protect him.
Overall, Episode 8 delivered a perfect mix of grotesque horror, folklore mystery, and emotional tension, leaving fans desperate for Episode 9.
