Napoleon Maiden ~A maiden without the word impossible~

Change your destiny. Impossible is a word to be found only in the dictionary of fools.

Shoichi Sakikawa was a normal, second-year high school student.
Or, he was, until he woke up from a car accident only to find
himself trapped in mid-revolution 19th century France.
What saved him from an onslaught of bullets was a girl armed with a sword.
“I am Napoleon Bonaparte. And one day I shall be ruler of all France.”
Having been saved by this “Napoleon” in the form of a girl,
Shoichi ends up accompanying her on her quest.
But in this world, not only is the past distorted,
but the gods grant chosen girls the gift of greatness,
who in turn fight one another using superhuman abilities known as “Tenkei.”

Will Shoichi be able to return to his own world?
And what will become of his growing bond with Napoleon?
