MTL - The World of the Pirate Consort - Chapter 22

A young boy, Asuma Haruto, is transferred to another world. Without having any means to return home, he has no choice but to live in this parallel universe.

Armed with only his knowledge of making soap, will Haruto be able to safely make a living here?

This is a story about how our protagonist creates his own business out of his hobby of making soap and then gradually manages his business and gets rich.

The pessimistic and negative daughter of a concubine living in the ancient times thought – since life is so difficult, why should one invest serious effort in struggling to live?

The life of an ancient noble woman is often determined and controlled by her family. Moreover, one’s actions often implicate one’s entire family – thus, it is fairly common to see an unexpected calamity result in suffering borne by one’s whole family. Managing to live a good and successful life while retaining one’s dignity is simply too difficult to achieve.

Ah, living in the ancient times is simply too dangerous – we should all just sleep till we die.
