I finally managed to be up-to-date with the first manga series for the series challenge:
Shinshi Doumei Cross - The Gentlemen's Alliance by Arina Tanemura
Arina Tanemura has a few really wonderful series out, but this is the first one I am now up-to-date as it is my favorite so far.
The main character is Haine Otomiya, a student at the "Royal Academy", a very expensive private academy, where classes are set up in three categories, depending on the students' family's wealth. The higher the category they belong to, the more privileges they enjoy, but only one student is in the gold category, the highest one - Togu Shizumasa. He is the student council president and school leader, called "The Emperor". It happens to be he, whom Haine is enamored with, but since she belongs to the bronze category only, she has to work hard to earn money. That way, he stays far away for her, even though she tries to get closer to him.
I have now read the first 7 volumes and I can only hope it won't take too long for the next one to be translated and published. Whenever I read one of the volumes out already, I fell right back into the story of Haine and Shizumasa-sama (-sama is the way highky respected people in Japan are addressed) and all the other characters. It is a lovely story and I hope it'll continue for a while.
My ratings for the first 7 volumes were A- for all of them.
