Quotes

 * “The moment human beings start to wither away...is when they start weaning. A fetus receives blood though its umbilical cord...And breast milk is just blood of a different color. In other words, if we had never been weaned off our mother's milk. We would never have to grow old.” (Momomichi explaining his motives to Takumi Hijirihara)
