If you liked the Akagami no Shirayukihime manga, the Anime-Planet community thinks you'd like:
A fierce war has raged between neighboring kingdoms Senan and Belquat for over 200 years, but that long period of turmoil is about to end. As a matter of custom, Nakaba, the royal princess of Senan, is sent to Belquat against her will as a peace offering, and arranged to marry the selfish Prince Caesar. Stranded in this inhospitable new land, Nakaba's sole confidant is Loki, her loyal dog-eared demi-human servant. But is he enough to help the girl navigate discriminatory customs, cruel nobility disgusted by her odd fiery red hair, and a strange new power awakening within herself?
Both manga are about a girl with red hair that attracts the attention of others and has often gotten her in trouble. The heroine lives in a castle and is close to the second prince and sometimes she happens to get involved in political or diplomatical affairs. While Akagami no Shirayukihime is a rather light-hearted manga Reimei no Arcana is a bit darker but both feature a capable heroine who tries to help others and opposes injustice.
Both have female leads with bright red hair that attracts the attention of others. They both involve relationships with the second prince of a country and have a complex relationship between the prince and the servant.
the concept and setting is the same. Even the prince and commoner "plot". The color of the heroine's hair is actually the same for the two. Finally, both are a good read. It has a strong heroine which you won't get pissed off.
Very similar, fierce and determined heroines, the male counterparts are also very admirable. The plotlines, though differing, both contain elements of fantastical worlds and a sense of adventure.
In both manga the heroine meets a prince in disguise and they become friends. Because of that meeting she decides to study hard so she can work at the palace and be of help to the prince.
both involve a girl getting a job at the palace to be closer to the prince and both girls treat the prince as if he is a normal person.
Kilala is a girl who wants nothing more than to find true love, just like the Disney princesses she loves and admires. One day Kilala finds a beautiful boy passed out on the ground and awakens him with a Sleeping Beauty-style kiss. His name is Rei, and he (and his companion Valdou) are searching for the owner of a tiara; this ‘chosen princess' is said to be able to save their country across the sea. After Kilala's friend Erica is kidnapped for winning a princess contest, Kilala sets forth on an adventure with Rei to find her and beyond. Together, they travel to the worlds of many Disney princesses, make new friends, defeat powerful enemies and even find true love!
The epitamy of priness romance. Both stories feature strong women, a fairytale love, and the struggle to be with your prince. Kilala Princess is very cute and a little more cheesy but enjoyable nontheless.
