    Incredible, combining slice-of-life and horror!

    This episode was both a perfect adaptation of the manga and a perfect continuation to the series.

    The animation and scenery were both beautiful, and the pacing was great. While this was a more slice-of-life episode, it developed both leads excellently and foreshadowed potential later plot points very well. It kept a tense atmosphere while allowing for lighter moments.

    Also, it was great to see more on Yoshiki's sexuality. It was nice to hear a character explicitly say "LGBT".

    So don't let people's unfairly low ratings trick you!

    Amazing Episode

    Episode 4 of The Summer Hikaru Died continues to deepen the unsettling mystery surrounding Hikaru's transformation and Yoshiki's desperate attachment. This installment effectively ratchets up the tension, pushing both the supernatural elements and the psychological drama to new heights.

    The episode largely focuses on the aftermath of the previous revelations, with Yoshiki grappling more intensely with the reality of the entity inhabiting his best friend's body. We see his internal conflict amplified, torn between the familiar comfort of "Hikaru" and the chilling awareness of what truly lies beneath. The pacing here is deliberate, allowing the viewer to sink into Yoshiki's isolated despair and growing paranoia. The subtle shifts in the entity's behavior, sometimes eerily human and at other times distinctly alien, are masterfully executed, keeping both Yoshiki and the audience on edge.

    A significant strength of this episode is its continued exploration of the rural setting and its folklore. The village's superstitions and the growing unease among its inhabitants serve as a palpable backdrop, hinting at a larger, more ancient horror at play. The visual storytelling remains strong, utilizing atmospheric lighting and unsettling imagery to convey a pervasive sense of dread. The sound design, too, plays a crucial role, with ambient noises and sudden silences contributing to the episode's chilling atmosphere.

    Overall, Episode 4 is a compelling continuation, successfully building on the established premise. It doesn't offer many answers, but instead meticulously crafts a suffocating sense of suspense and emotional turmoil. The episode leaves you with more questions than before, solidifying its place as a truly unsettling and thought-provoking horror narrative.
