Reincarnated as a Hero- and the Wrong Gender?!

Harutora didn't lead a troubled life- he was about as normal as they come, with solid grades and a normal-enough girlfriend. His normal existence however, one day came crashing to an all-too-abrupt end when he collapses from a heart attack seemingly for no reason at all-! Turns out, mages from another world rarely wait for a good time to summon you. Thrown into a world that he doesn't know or understand, Harutora finds himself hunted as a "Failed summon"- but more than that, he's become a woman?! A demi-human, no less!! Fleeing from a nation that wishes to exterminate the botched summons, Harutora must adapt to his new guise and choose between fight or flight. What is a young man to do, though, when faced with the horrors of war, and shoved headfirst into the darkest truths of the world, when he'd known nothing but peace, before? //Will be posting this story on Royalroad.com as well just for exposure, under the un Tunabun — Description from novelcodex.org
