There are several similarities between Karichama Karin and 11eyes. First of all, there are characters who can transform to battle foes. And magic is also performed during fights. Secondly, there is a bit of romance included between more than just the main characters. Also, there is a character in both animes who has two different-colored eyes.
I'm sure if you liked one, you'll like the other.
One night, Madoka has a terrible nightmare – against the backdrop of a desolate landscape, she watches a magical girl battle a terrifying creature, and lose. The next day, the teen's dream becomes reality when the girl – Homura – arrives at Mitakihara Middle School as a transfer student, mysteriously warning Madoka to stay just the way she is. But when she and her best friend Miki are pulled into a twisted illusion world and meet a magical creature named Kyubey, the pair discovers that magical girls are real, and what's more, they can choose to become one. All they must do is sign a contract with Kyubey and agree to fight witches that spread despair to the human world, and in return they will be granted a single wish. However, as Homura's omen suggests, there's far more to becoming a magical girl than Madoka and Miki realize...
The main characters are fighting off an apocalypse. However, in doing so they find tragedy ends up following them no matter what they do. There are also alternate worlds/realities, not to mention multiple time lines. Both series styles are nice as well.
At the end of the 20th century a fierce war raged between the Monsters and the humans. The outcome was devastating for humanity -- as the Monsters had won -- and thus a new era of Monster-ruling began. These Monsters feed on children and can turn any human who sees them into either a puppet or stone -- except for the Melos Warriors who are the only ones able to fight them. Meet Bokka, a young aspiring Melos Warrior whose only goal is quite simple: to save the Melody of Oblivion and vanquish the Monster King, once and for all!
This is definitely a gut feeling recommendation, but I have a feeling that if you liked one of these you might like the other. Both are somewhat dark fantasy with creatures to deal with, and have a really similar mood and feel. Again, call it a gut feeling, but try it on for size.
By normal standards both of these titles do not receive much (or any) love from it's viewer ship. If you like either series though, you like the other. Both are set in places that contain "two worlds" and at the same time the main character is oblivious of the other world until a strange twist of fate that makes the Male lead the central focus of the other world.
