Ga-Rei: Zero, Mahou Shoujo Madoka★Magica Recommendations
Supernatural dark-themed catfight with casualties. The timing of event is so well done you will be surprised and can't wait-until-next-week. Kickass combat keep you glued to your seat when the next-week finally comes. Entire lesbian casts keep you sealed to your seat once more when the next next episode come. And finally when the next next next week come once again, here come explicit confession of lesbianship on air, which once more stick you to your seat.
Short summary? Explicit Yuri (lesbian) attitudes, beautiful combat sequences, girls politic presented unlike your average Sex and the City catfight, great screenplay, and well timed stories will keep
Concept of stones is somewhat, only somewhat similar, the making and breaking of friendships, the hardships of one's fate. Concept overall is similar. Both are anime that show that happy times then take it all away.
If you like one, you'd definitely like the other. Both are really good anime
Both anime contain action as well as drama, are about fighting 'evil things' and have a slight yuri touch to it. Basically, they both have the same 'shounen-meets-shoujo' feel.
