Arisa is an amazing teen manga series. The story focuses on Tsubasa, who has been separated from her twin, Arisa, for many years and has only stayed in contact with her through secret letters. When the pair finally meet up again, Tsubasa (Who's also known as the 'Demon Princess' at her school and who only has male friends) can't stop talking about how great her sister's life seems. Arisa thinks otherwise though, and soon jumps out a window. Arisa lives, but she's thrown into a coma, and now Tsubasa wants to find out what could have caused her sister's suicidal behavior.
Once Tsubasa starts acting like her sister, she finds that her sisters class practically worships an unknown person known only as 'The King'. The King can grant wishes, from anything like giving somebody the answers to a test or to getting rid of somebody. Yikes. And now it's up to Tsubasa to find out who The King is.
The story is very exciting and has many twists and turns that leave the audience guessing. The overall feel of the story is very tense and there's constant threat of danger. Though it's a shojo manga, and there is a little romance, it is by no means a promenant theme of the story, and I see how the plot can appeal to many people. If you haven't picked this one up yet, I highly recommend this series.
