Another, Hyouka Recommendations
These both have the same "aura" when it comes to mysteries . Hyouka is more on club activities while another is more on finding the root.
Although it isn't a horror anime like Another, Hyouka is an excellent anime for those who like mystery. And while for some people Another was lacking in romance/relationships, Hyouka's characters grow and change throughout it. Maybe I'm grasping at straws here because this is my first recommendation, but I think Hyouka is a better version of Another with deeper characters, less blood, and a better plot.
Personally, I find that Hyouka and Another have a similar atmosphere, despite the fact one is a horror and the other is a mystery. Both aren't very lively or comical, neither do they rely on fanservice.
-Almost depressive character with a lead role
-Finding answers plays a large part of the storyline
-One is horror, the other is mystery
-One of which has a highly energetic character
-Hyouka has a slightly notable romantic element
If you've watched either of these, I'm pretty sure you'll also like the other due to the similar feel and foundation behind each.
Mystery/romance; Another is much more bloody, gorey, and creepy than Hyouka, but still a mystery romance nonetheless. Main hetero couple has personality reversal compared to Hyouka, though. Also, there's a lot less romance. But it still takes place at a school.
