MKR is a Clamp anime about three girls who are taken from Tokyo during a school field trip, and transported into a fantasy world. Hikaru Shidou, Umi Ryuzaaki, and Fuu Hououji must fight a slew of enemies, overcome trials and tribulations, and face their inner demons to save Cephiro, a wonderfully detailed world, from a dastardly evil and powerful Priest, Zagato.
Life can be tough when you're a teenager. Enter Tsukino Usagi, an average, if somewhat clumsy, junior high student whose voracious appetite for sweets and capacity for tears are offset by her enthusiasm for life. Her normal existence is suddenly turned upside down when a talking cat named Luna comes into her life. Suddenly, Usagi finds herself with the ability to transform into the superhero known as Sailor Moon. Fighting the occasional monster may be the least of her worries, though...
Both have magical girl teams that are fighting for a purpose they believe in. The characters in Magic Knight Rayearth don't transform as they do in Sailor Moon, but if you like magical girl anime, Magic Knight Rayearth and Sailor Moon are good ones. Though, Magic Knight Rayearth is a little more serious than Sailor Moon. Go check out their adventure to bring peace!
The idea of fighting girls using magical powers is mainly what those two series have in common. Apart from that, there is also this thing with hair color connected with battle style and love plot involved.
Both are great starter animes for any person just getting into the fandom. Both being from the magical girl genre, they sort of have the same feel and elements and somewhat similar story lines ("fight to save the princess").
Hitomi was just a normal high school girl, until she was taken by the mysterious Van Fanel and dropped into a world of romance, magic and giant sword-wielding armor suits! Now Van, pilot of the famed armor suit Escaflowne; and Hitomi, whose hobby of predicting the future just became a frightening reality, must work together and fight the advanced technology of Zaibach: a force who want to shape Gaea to their visions of "peace". Follow Hitomi in her struggles against both these forces who seek to conquer this world, and her own confused heart.
Magical Knights Rayearth and The Vision of Escaflowne both have characters that pulled from the "real" world to a fantasy one. That's a very common theme though, the interesting thing about both series is instead of just being pure fantasy realms, they involve fantasy mecha and other technology like airships. Rayearth is more comedic until the end when it turns quite dark, while Escaflowne is more dark all the way through. That said, if you like fantasy style mecha, both are good choices.
Both anime have seemingly normal school girls transported to a parallel universe to aid in the insuing chaos with a particular planet. They feature mecha, action, adventure, and comedy (though the latter may apply more to MKR than Escaflowne).
Kagome is a normal high school girl who falls into a well, transporting her back in time to the feudal era. Upon her arrival to this world, she mercifully unleashes Inuyasha, a half demon. As if this isn't enough, she also discovers that she is the bearer of the Shikon no Tama, a jewel of great spiritual power, a jewel which has just shattered into a million shards. Now, along with Miroku the priest, Sango the demon hunter, and Shippou the mischievious fox-demon, they must set out to find the Shikon shards and defeat the evils of the demon Naraku.
In both anime main characters are much alike - they are taken from present to a different world, where their powers are awaken, and they have to face a new, troublesome situation and are basically left with no choice as wheter to return or to stay and help this fantasy world's inhabitants.
Girls get swooped away and taken to another point in time in both anime. InuYasha only has one girl that this happens to where MKR has 3 but they are all quite shocked and determined to find their way back home while fighting monsters and defeating demons. Animation styles are pretty similar but the humor is quite differnt. Check one out if you liked the other.
Meet Lina Inverse, a mighty sorceress who fights evil in the name of... greed, gluttony and black magic?! When she meets Gourry, a swordsman whose skill with the blade is rivaled only by his stupidity, Zelgadis, a grumpy sorceror who's been turned into a golem, and Rezo, a priest known for his benevolence (with a dark secret), you know her adventures are just beginning!
Basically - group of friends, with different magical skills, travel in some fantasy world in order to achieve their goal. Lots of fighing and humorous scenes invlolved as well. After watching one, you should try another :)
While reading "The Universe of the Four Gods", best friends Miaka and Yui are mysteriously transported into a strange world full of magic and unfamiliar faces. As if their arrival was determined by fate, Miaka is revered as the Priestess of Suzaku, the savior of their warring country, who was destined to arrived in a flash of light, from a land far away. Betrayal, love, and heartache accompany this fantasy-filled tale of friendships torn apart, and hope that never fades.
Both these animes have a lot in common, the girls in both stories are transported from their normal lives when the major thing they had to worry about was school to a magical world which they have to save, everyone who has seen one of these episodes will very much like the other, although magic knight rayearth does not have as much romance as Fushigi Yugi.
