Recap of The Summer Hikaru Died Episode 3

The episode opened with a brief flashback to Hikaru and Yoshiki’s childhood, where they ate watermelons. In the present, Yoshiki arrived at Hikaru’s house with a watermelon of his own. Still burdened by the loss of his friend, he sat silently, deep in thought. As he texted Rie, Hikaru’s mother called him into the kitchen. Upstairs, the thing had already noticed the message.
Later, Yoshiki met up with Rie and told her everything about the strange new “Hikaru” and how things had changed. Rie warned that the bizarre events currently happening in the village only began after Hikaru’s transformation. She suggested that whatever he was, maybe he belonged on the mountain. Urging caution, she told Yoshiki to keep his distance from that thing.

Back at school, Yoshiki tried to avoid Hikaru, but Hikaru found him and asked if they could walk home together. Yoshiki refused, and the tension between them grew. Realizing that Yoshiki no longer saw him as the real Hikaru, the entity lost control and attacked. However, he stopped himself in time, said he couldn’t hurt Yoshiki, and quietly walked away.
The next morning, Hikaru didn’t show up to school. Worried, Yoshiki rushed to his house to check on him, and the two quietly made amends. To himself, Yoshiki reflected that this Hikaru was like a young child who didn’t know anything and if that’s the case, then it was up to him to teach him a few things.
What to Expect from The Summer Hikaru Died Episode 4

Episode 4 may reveal whether the creature inside Hikaru is gaining more control. Yoshiki’s silence and growing fear suggest that his mental state is beginning to slip. If he keeps ignoring the truth, he could put himself and others in danger.
Episode 3 focuses solely on Yoshiki and his feelings toward the entity that took over Hikaru’s body. The next episode might shift focus to the village, with strange phenomena beginning to occur and Tanaka investigating the incidents. He could soon get closer to uncovering that Hikaru is at the center of it all.
