Higurashi no Naku Koro ni Kai
|
These series aren't alike at all really. But at the same time there is something that sort of reminds me of the other. While in Higurashi the characters are close they aren't so much in Bokurano. There is an hanging feeling of hopelessness and despair in Bokurano because of what happens to the pilots of the Zearth the same hopelessness and despair is easily found in Higurashi too.

Soul Eater
|
Both have a creepy gothic atmosphere (although Soul Eater stresses it more) dealing with monsters or evil souls. On the surface they don't seem very alike but if you liked one you might enjoy the other too.
If you liked
Mushi-Uta
|
...then you might like
Ayakashi
|
Both are very similar but different too. Some of the characters share same roles and strange creatures/monsters play a big part too. Both look sort of the same in style (but Mushi-Uta looks much nicer). One big thing is that Mushi-Uta is way better anime and Ayakashi is very gory.

Both feature a large cast and a unique(ish) fantasy world. The females of either series also double as weapons. So that's fun too.

Kaibutsu Oujo

Boku no Marie

They share lots of similar riles even though Marie is less child-like and mindless than Chi. But if you liked Chobits you might like My Dear Marie, both feature guys with robot girlfriends in ecchi situations!

Tsukiyomi

Creepy, but in a good way. Cute, but in a fashionable way. Funny, but in a dramatic way. And just enough to leave you hanging on until the next volume.
