Horror anime often feels overlooked compared to other genres like action-packed shonen series. Though some works by artists like Junji Ito have been adapted, many spooky manga stories don’t get the same attention. Fortunately, Netflix recently took a chance on a popular horror manga, and it’s proven successful. The anime adaptation, produced by Cygames, has been renewed for a second season and is boosting the popularity of the original manga.
Netflix released the anime series The Summer Hikaru Died this summer, adapting the original manga by Mokumokuren. The story centers around Yoshiki Tsujinaka and his friend Hikaru, who mysteriously returns from the dead. The series is praised for its strong character development and genuinely frightening atmosphere. The anime’s popularity has boosted manga sales to 4.5 million copies, establishing it as a leading horror manga. With new chapters still being published, the future looks bright for this series and its characters.
Why You Should Be Creeped Out by Hikaru

It’s surprisingly difficult to create truly frightening moments in anime, which might explain why there aren’t as many horror series compared to action or romantic comedies. However, The Summer Hikaru Died seems to pull it off effortlessly, consistently delivering genuinely creepy and unsettling scenes. The story centers around Yoshiki Tsujinaka, a deeply troubled character grappling with a friend who’s changed drastically, as well as his own struggles with depression and isolation. Beyond the well-developed characters, the anime features some truly frightening figures brought to life with effective animation.
Viewers might question why Yoshiki doesn’t immediately distance himself from Hikaru after learning he’s a spirit, but that hesitation is what makes the story so compelling. We see Yoshiki genuinely struggle with the unsettling truth about his best friend. The supernatural elements, including Hikaru and the creatures invading the town, are truly unique in anime, creating a constant sense of dread and tension, even in quiet moments. If Netflix renews the series for a second season, expect even more chilling and disturbing scenes.
