Hello there!

This is the most reliable place when I need help finding a manga ^_^ Anyways, if you know the title of this work, much thanks in advance! The genre is not yaoi though it may have some subtle shounen ai. I read it a reeeaaally long time ago so I may be mixing the plot up with another work similar to it..

Summary: It's basically a prequel to how the main story's villain came to be and why he is the way he is, along with why his supporters are so loyal to him. I'm pretty sure the setting is like a military high school and he has a best friend who is a guy and I think has 'foreigner' characteristics. The protagonist/villain is the top of his class (of course) and has respectable values and dreams, but an event somehow forces him to take the role as a villain to the world. The part that may be another manga is that he is destined to be a hero/prodigy whose purpose is to save the world but then a girl appears later on *spoiler* who is supposed to replace him.

Sorry it's so vague, but I do know that it is based off a light novel series. Again, thanks a bunch in advance! :)
