If you liked the Maria-sama ga Miteru anime, the Anime-Planet community thinks you'd like:
When nobleman and gypsy-born Serge Batouille arrived at Laconblade Academy, he had no idea his life would change forever. Upon arriving, he is roomed with the sexually-voracious and flirtatious Gilbert Cocteau, which ensures that life at the prestigious school will dole out more complications and confrontations than either boy has dealt with in the past. Together, these two young men brave love, growth, and the pain of youth, all while growing closer together than anyone would have thought...
Both series take place at schools of all one gender (boys for one, girls for the other), and have similar themes of forbidden love. This love does manage to remain relatively low key,when it comes to the main characters. Both also have a rather similar pacing and feel to them, so if you enjoyed one, you are likely to enjoy the other.
Neo Venezia, the pride of planet Aqua, is a quaint city filled with canals and easy-going people. Many companies operate their gondolas on the canals, giving tours to tourists and locals alike, but the most famous of them is the Aria Company. Follow the adventures of Aria's young apprentice, Akari, as she learns the tricks of the trade from her beautiful senior, Alicia. Together with her friends Aika and Alice, apprentices of rival companies, and their seniors Akira and Athena, they train their skills as gondoliers, meeting new people and learning new things about the city each day.
Both shows are about a group of girls, slowly growing up. In Both cases we have very close friendship bewteen younger girls and very important senpai-kouhai bond between the younger and the older girls (though in Marimite this relationship is way more intimate). Both are heartwarming coming of age stories.
Even though the differences are big ( Marimite have some mild drama, and the relationship is close to shoujo-ai, also Aria unlike Marimite is episodic) I think that if you like one of them you will like both.
Average, boring, and nothing special; this is how Shiratori Kuu feels about herself and her life as a high school student in Academia. On what begins as any other day, Kuu's life is spun upside down when a new student transfers to her class. As soon as she sees his face, she is astonished, for this is no ordinary boy – he looks just like the prince she has dreamt of for so long! He extends a hand to her and repeats the words she has somehow heard before, "Lets go... Together." But it is never that easy, is it? A world that seemed so dull is now torn apart by a whirlwind of love and hate, and the conflict that plagues all those involved.
Maria-sama ga Miteru and Kyoshiro to Towa no Sora both leave you with a similar feeling (an elegant feeling, mind you).
The main characters are girls with very bad self-asteem, surronded by a lot of elegance. Relationships are important to both series, though with KtTnS has more romance.
Lastly, both series contains elements of shoujo-ai, without being true shoujo-ai animes (KtTnS focusing on a hetero couple, MsgM mostly not going beyond hints).
Kanako Miyamae hates boys so much that she breaks out into hives after any physical contact with them. So when she is able to transfer to the Ame no Kisaki Girl’s school, Kanako is overjoyed that she can now search for her fated yuri partner. When she arrives, Kanako meets Shidou Mariya, a beautiful young girl who is exactly her type... except that Mariya is really a sarcastic and sadistic young boy who is masquerading as a girl! With no intention of being expelled from school, Mariya threatens Kanako into keeping his secret, and decides to guard her twenty-four hours a day to ensure that she does. Now Kanako must share a room with Mariya who is gleefully making her life a misery while using his ‘feminine’ charms to stop her protesting. Throw into the mix Ryuuken, the most popular girl in school who has vowed to protect her; and Kiri - who claims they are dating to prevent her from being bullied - and it seems as if Kanako’s dream of all-girl school life will be nothing like she imagined!
It was a time of political instability. While most of Europe was involved with power struggles, the island country of Kuchen followed its own independent path; and with the leadership of an intelligent king and his advisors, the people worked to restore their kingdom. These advisors, with strong minds and good backgrounds, were graduates of a prestigious boarding school known as the Rozenstolz Academy. Follow the lives of the five students with the potential to become the king's next advisors (known as the Strahl candidates), as they strive to achieve their dreams.
Both Meine Liebe and Maria-sama ga Miteru focus on an almost single gender cast (boys in Meine Liebe and girls in Maria-sama ga Miteru) attending a private academy, and the (supposedly, in some cases) prim and proper students that attend it. Meine Liebe focuses more on politics and dueling than Maria-sama ga Miteru, but both still have the ranking and social status pretenses in them. Both also use foreign language and concepts in them (German and French, respectively), and have hints at shoujo or shounen-ai at times. Both are very character driven, dramatic series - if you liked one, be sure to check out the other.
