Let's Buy the Land and Cultivate It in a Different World (Manga) Vol. 7

Kidan possesses a gift called the Supreme Wielder and was summoned to another world. Together with the mermaid Plattie and the dragon Veel, he has built a homestead on the frontier. His farm goes ever larger. Elves, demons, witches, and humans are all welcome. One day, an angel appears on the farm. Here angels were made by the gods four thousand years ago. They are living weapons with the power to destroy the world. This angel seems peaceful now, but how long will that peace last?
