[Multiple races + demi-human beast girls + no System + Western fantasy + character development]
After transmigrating to the Middle Ages, he becomes an adventurer.
Doran learns that this world has not only scholars and mages, but also beautiful Awakened Ones, whom people have a chance of becoming once they reach adulthood.
With his natural talent and his experience romancing characters in anime and games, Doran successfully wins the favor of one Awakened One after another.
Faced with the evil cults from beyond the borders and the Demon Emperor, the ultimate target of the heroes, Doran merely gives a scornful smile.
So what if the Demon Emperor is a few hundred years old? I can still win her over!
