Aided by his past-life memories, Ash went through strenuous efforts at his village to recreate the convenient and bountiful life recorded in the legends of the ancient civilization in this world. As a result, he obtained the right to study alongside Maika in Itsutsu city, where a vast collection of unseen books awaits him.
At his arrival, Ash is welcomed by the acting count Itsuki, as well as a girl disguised as the former’s younger brother, Arthur. But more importantly, he is faced with the disappointing reality of the city’s lacking resources and outdated technology.
Ash enlists Maika and Arthur to change that reality. They start by trying to figure out a way to use some supposedly poisonous crops and repurpose the dangerous compost. Meanwhile, the “demons” responsible for the decline of humanity are lurking in the shadows.
This is the second chapter of the story about a young boy who sets out to revolutionize the world in order to rebuild civilization and create his ideal life!
