I reincarnated into another world with a craft system

Amano Kizuna, NEET, loner, otaku etcetera etcetera died before he could watch the anime of his favorite harem light novel find himself reincarnated in another world. Usually, people who have been reincarnated will be a hero and save the world but it was different for Kizuna. He was given the job of Builder and his mission is to rebuild the world to be a better place.



Having made a promise to the goddess, he seeks on his own adventure different from other isekai heroes. Can he achieve his dream of having his own harem though?
