Setting the Stage: What Makes Summer 2025 Special
This season feels like it struck a rare balance: heavy on the supernatural / horror elements, strong returns for beloved series, high emotional stakes, and some twists that push character relationships into uncomfortable but fascinating territory. Animation styles vary, tonal risks are being taken, and the season’s lineup includes both shock and softness—loss, change, identity.
“The Summer Hikaru Died” — Heart, Horror, and the Uncanny
This show is a standout, both for how it blends horror, cosmic weirdness, and human grief, and for how it leans into existential questions of identity and love in the face of loss. Here are the high points and what makes it so compelling:
What it is
-
Based on the manga Hikaru ga Shinda Natsu by Mokumokuren.
-
Produced by CygamesPictures, it premiered in July 2025 and runs 12 episodes.
-
It mixes slice-of-life friendship/childhood bonds with horror and supernatural themes.
Core Story & Themes
At its center are Yoshiki and Hikaru, childhood friends. Hikaru dies in a hiking accident (tragic, snowy mountain, visceral), but returns—or rather, something returns in his form. It has memories, maybe some feelings, but Yoshiki slowly realizes this entity is not quite the real Hikaru.
The themes are powerful:
-
Grief & acceptance: Yoshiki’s journey is heartbreaking—not just to lose Hikaru, but to lose what Hikaru was, and question whether this “returned” version can ever fill that void.
-
Identity: What makes someone “them”? Physical appearance? Memories? Emotional bond? The anime pushes these questions.
-
Otherness & humanity: The impostor is innocent in many ways, curious, wanting connection—but inherently alien. What does “living as human” even mean for it?
What’s Working, and What Raises Unease
What really helps the show land is atmosphere — the contrast between mundane rural life (festivals, streams, friendships) and the creeping, uncanny strangeness. Small details (a shattered barrier, a festival, a cat that flees “Hikaru”) build dread slow.
Also the emotional draw: Yoshiki’s desire to keep the impostor around is totally understandable; letting go is harder than accepting a lie. There’s tension, not in what happens externally only, but internally—how far kindness, love, memory can go in defining truth.
On the other hand, horror-fans might want more clarity—and some horror tropes aren’t pushed quite far enough (depending on tolerance). The pacing sometimes leans into introspection so much that external plot threads (other beings, hunters, etc.) feel like they’re percolating rather than fully urgent yet. But that might be intentional: to let the personal horror marinate.
Place in the Season & Why It Resonates
Compared to many shows this summer, The Summer Hikaru Died is less about spectacle (so far) and more about mood, character, feeling. It resonates when you want something haunting, with emotional complexity. It’s closer to a psychological horror / body horror cousin of works like Another, Shiki, maybe even When They Cry. But it also has a gentleness, a love story of loss.
It’s the kind of anime that stays with you after an episode ends—making you think, revisit feelings, rewind flashbacks. In a season full of action, bizarre ghosts, high stakes fights, it offers a slower burn. And sometimes, that’s more painful.
Other Honorable mentions of Summer 2025!
Sakamoto Day
Sakamoto Days gives you adrenaline, combat choreography, humor, and that “one punch / bullet away” tension. It doesn’t dwell as much on grief or identity (at least not yet) as Hikaru does, but where Hikaru is internal, Sakamoto Days is external. Where Hikaru is creepy and intimate, Sakamoto roars.
DanDaDan (Season 2)
DanDaDan is more chaotic, more genre-blending in a whiplash way: you laugh, you jump, you get weird chills all in one episode. Hikaru is more singular in tone. DanDaDan offers breadth and punch; Hikaru offers depth and haunting aftereffects. If DanDaDan is riding the roller coaster, Hikaru is walking through a fog.
Call of the Night (Season 2)
Call of the Night shares with Hikaru the emotional / romantic tension and supernatural overtones. But its mood is more sensual, more melancholy in a different register—not horror so much as longing, and fear of exposure. Hikaru has that same longing (Yoshiki wants Hikaru back) but paired with fear, dread, and alienation. Call of the Night more often balances desire and danger, whereas Hikaru leans toward the danger of losing what you love—not just physically, but what defines your relationship.
Overall Feel & Personal Take
For me, The Summer Hikaru Died is the dark horse of Summer 2025. It’s not trying to be the biggest, loudest, fastest—it’s trying to hurt you in a way that lingers. It's the kind of show that haunts your dreams, or makes you remember your own lost friendships. The pain of letting someone you love go—and what you’d hold on to instead—is a universal wound.
Where it wins is in emotional authenticity: the way Yoshiki’s love for Hikaru, even when broken, feels real; the way the “impostor” cares (or tries to) feels messy and precious. It’s not clean. Horror often isn’t. And that messiness is compelling.
