Daybreak on Hyperion by Aorii

Orignal English School Life Gender Bender Military Strategy Politics Transported to Another World Fantasy
Born into noble prestige and gifted with genius intellect, Pascal was a promising officer cadet who rose to national fame before even graduating. At the mere age of nineteen, he had everything a young man could wish for...

Except his habitual arrogance had destroyed every opportunity of a close friendship.

Seeking a companion that would meet his protracted list of requirements, Pascal decided to craft the 'perfect spell' for the upcoming familiar ceremony. If those in his world were not fit to accompany his brilliance, then he would summon a best friend through his own hands -- one that was mature, intelligent, knowledgeable, bright, and cute to boot.

He received far more than he bargained for.

This is the story of how three wills joined and forever altered a continent.
