Honoka Takamiya is a typical teenager; he does his classwork and admires Ayaka, the school idol, who sits next to him in class. But the boy's life changes forever when one day, a piece of the school falls on top of him and he's saved by Ayaka due to... her magical powers?! For Ayaka is a witch, and deeming Honoka to be 'her princess', she is determined to keep the boy safe from harm. Now Honoka must try to stay alive while countless other witches target him, learn more about Ayaka and her craft, and still try to maintain his school life in the process!
Both Magico and Witchcraft Works feature a normal human protagonist within whom some secret power is hidden and a powerful mage set on protecting him\her. Also both of those manga feature some subtle romance. Last but not least, the genders are reversed: in Magico the "damsel in distress" is female and her protector is male, but in Witchcraft Works the first one is male and the second female. It's quite possible that you might like one of those if you liked the other, so give it a go.
Asuka Masamune is a manly man who's the complete opposite deep down - he loves sewing, cooking and all things girly! As his father left when he was a child to live as a woman, Asuka was raised to be the boy he is, but he can't forget his true nature. Now, as a teen, Asuka finds himself in the company of Ryou, a boyish girl he's fallen head over heels for; Juuta, a secret writer of shoujo manga who's modeled a character after Asuka; and a variety of others such as his self-proclaimed apprentice Yamato. Can Asuka learn how to balance his two sides and finally get the girl he loves?
Those may look like two most unlike series to have something in common, but on a closer look there actually is something there. In both series gender role reversal is a major theme (if you pay close attention to the male lead in Witchcraft Works, you'll notice that he does share some similarities with the male lead from Otomen). If that's the theme you're after, I encourage you to give both a try.
Both manga have somehwat similar female lead. In both cases it is a rich and non-emotional girl who declares that she will protect that average guy male lead. Though the guy in Shiki Tsukai is a bit above the average and despite what the girl promised to do, he actually has to fight himself. Nonetheless, if you liked one of those female leads you might find the other manga interesting too.
P.S. In both series the male lead is called a "princess" at some point...
There are some similarities between Witchcraft Works and Trinity Seven, like the protagonist suddenly finding himself surrounded by mages\witches, but truth to be told, I wanted to use the differences between those two series to encourige you to read Trinity Seven. Do you have enough of those wimpy, indecisive male leads? If the answer to that question is "yes", then Trinity Seven, might be just what you are looking for. The protagonist there openly states what's on his mind (witch often get him into trouble), and stays cool through (almost) any crisis. As a bonus it also has a high school setting, magic and mages.
