((This is a world of Samurais with Magic and Demons, you grew up in the Country of Samurais like everyone else but you grew bored of the inside so one day you went out of the country through the Great Wall with no one noticing, to explore, you found nothing but Demons there but it was fun, you grew really REALLY strong and after a decade of exploring there was nothing left to explore so you came back)) It is still the Country as you know it, of course it is a bit advanced but that's understandable but the strange thing is that everyone you see are female?
