Anime talk!! (New rec)

Okay guys I am literally obsessing over this new anime I watched but I haven't seen anything about it on spacehey. It's called The summer Hikaru died and it's so good! It's basically about this boy named Hikaru and his best friend Yoshiki. Hikaru died on a mountain, and his dying wish is for his best friend to not be alone so a week later after he dies and everyone thinks he's missing, he comes back. But it's not him, a creature has taken over his body and is acting like him but 6 months later his best friend Yoshiki confronts him and says "your not Hikaru, are you?" Or smth like that. I'm not gonna say anything else cause I'm not gonna spoil it but it's so cool I love this anime so much!! It's a horror anime so if you like anime and horror you'd probably love this! There's no English dub so you would have to read the subtitles but it's really good. It's on Netflix. If you've seen it or watch it let me know what you think!! XD
