Michio is a Japanese high school student who was transported to another world. A rather reasonable and calm young man who decided to realize his dream of a quiet, comfortable life and a harem of several slaves in the new world. Despite the fact that he was often bullied in the old world, he did not get angry, but this causes him to sometimes manifest difficulties in communication and emotional tightness, as well as a thirst for human intimacy, love and friendship. Treats his slaves as family members, or rather wives, and expects the same attitude and trust in return. He takes care of his harem, does not force them to do anything and, on the contrary, provides them with everything they need and beyond: from food and clothing to weapons and education, helps them to level up and improves living conditions.
