    A Hauntingly Beautiful Mystery with Deep Emotions

    The Summer Hikaru Died is one of the most captivating anime debuts I've seen in years. From the first episode, it grips you with its eerie atmosphere, emotional weight, and beautiful direction. The story blends supernatural horror with slice of ife moments and an intense, slow-burning relationship between the two main characters, Yoshiki and "Hikaru."

    The animation is stunning not flashy, but subtle and haunting. The voice acting is top-notch, and the sound design adds to the chilling yet tender tone of the show. What really stands out, though, is the emotional core. The tension between grief, fear, and longing is portrayed so naturally. You feel Yoshiki's confusion and heartbreak.

    This anime doesn't shy away from its queer themes either. The bond between Yoshiki and the "thing" that took Hikaru's form is complex and layered, making it feel more human than most traditional romances. It's refreshing and raw.

    Goosebump

    Underrated and amazing waiting for it for a year finally watching it giving me goosebumps I wish people be more open minded and appreciate art and story it's truly amazing feeling connection with mc and something big going to happen in future the animation style is amazing and realistic. This really explain the grif that we feel after losing someone and teach how to let go of loved one it's really emotionally. But its not getting the apprition that it deserves the opening seance give horrer to you and it's really emotional to watch it i could recommend it to everyone to watch it and appreciate the story.

    THE Gay Horror Anime

    Technically speaking, 3 episodes isn't enough to proclaim this is a masterpiece, but as a big fan of body horror mixed with queer subtext (and straight up text, I mean-) this is really everything I've ever wished for in a beautifully animated package. Sound design? Amazing. Voice acting? Stellar. You can't ask for much more perfection, really - the complexity is well captured even if the content is undoubtedly less lengthy than the manga. I wonder what emotions they'll be able to pull out of me in the next episodes but so far, this is beautiful and should already be scheduled for a second season.

    l love it

    I haven't watched any anime in a long time, but I don't regret watching Hikaru. It also made me read the manga and I finished it in 2 days.

    The anime captures the atmosphere of the manga well, although I'm surprised that Tanaka appeared so early. But we'll see how it goes.

    I would also like to point out the good style and good music. That ending is SUPER.

    This is also one of those anime where I like all the characters. It's interesting to watch everyone!

    I've seen a lot of comments that they are confused by the fact that the main character is gay. On the contrary, I'm glad that queer characters can exist outside of BL.

    Beautiful

    Just beautiful. Until now (first two episodes), the mystery and the horror aspects are both great. Also the relationship between "Hikaru" and yoshiki is very interesting. I wonder where the story, their relationship and the horror and mystery aspects go. Other than that, the visuals are STUNNING, animation wise and in terms of style. It reminds me of high budget anime movies like your name by makoto shinkai a little bit. But what I enjoy about the visuals are two things. 1: the characters and 2: the atmosphere. All characters look unique and different without looking unrealistic like in most animes with weird hair colors and weird proportions. And the summer atmosphere is just spot an as well. Perfect.
