Shame Hidan no Aria AA will never be yuri and in the end will call it all friendship, the original story is a light novel like Hidan no Aria right? Someone knows how it's going? If they didn't introduce any male character to eventually end in het that just didn't show up in the anime yet or some shit like that?
And for those that like Mai-Hime, I talked with a friend about it and decided to read about the manga, you should never read the manga if you liked the anime, it's written by another guy who devolved it in a harem, Yuuchi is the main character, it's a mahou shoujo now and Himes need a partner to act as "key" to their powers, Yuuchi is Mai and Natsuki "key" and both are in love with him, later Shiho falls for him too, Haruka is a Hime instead of Shizuru who aparently became a side character with not much importance, chapter 1 they suffer cloth damage and goes downhill in 2, don't know if ends with Natsuki x Shizuru but I doubt it, this mangaka also made a spin off to Solty Rei that is suposedly connected to the anime and Yuri Tantei Yurianzu that is suposedly yuri and was discontinued, if you read it's tags you understand why, not a surprise he never made more mangas.
Mai-Otome is not as bad, but for reasons they turned Mashiro in a guy and Erstin and Nagi who are aparently even more gay in the manga fall for him because of other reasons, but Mai-Otome is made by the creators of the anime, so it shouldn't be much bad, but in the end all mangas from both series are alternate universes so you can ignore them as only the anime is canon.
