While both are similar, they each have such beautiful and unique stories that will - without a doubt, leave you in tears.
I agree with others that say these two have a lot of similarities. Even though they are alike in a lot of ways bother storylines seem to be really unique.
When it comes to supernatural, I feel like these two complement each other perfectly. Both have the perfect amount of romance, action, and so much more. The storylines are my favorites.
When I was watching Imawa no Kuni no Alice, I thought it reminded me a lot of Battle Royale. Although they are both different, they are similar in a lot of ways.
Both shows are really dark and have really interesting settings. It feels like they go hand in hand, honestly. Lol
Both really have a dark creepy vibe. If you finish one and wonder what other show is like it because you're in that kind of mood, I recommend these.
