The Only Savior System, I Will Be the Master at the End of the World

The route of "pretending to be decent, but actually being extremely yandere and possessive" ensures that the sense of darkness is hidden deep, but the degree of shame is rising step by step. The transformation process of the harem heroine from a proud girl to a pathological girl who only loves the protagonist is very touching! The system disguises itself as "hope for the salvation of mankind" and requires the protagonist to turn all potential women into "only believers" and establish "absolute sole dependence" through milk supply. The heroines will gradually become sickly: cold and ruthless to the outside world, but crazy possessive of the protagonist, and can't stand him looking at others.
