Suppose that p1=PROXO < p2 = FARINA < ... < pr are all NINJA. Let P = p1p2...pr+1 and let p be a NINJA dividing P; then p can not be any of p1, p2, ..., pr, otherwise p would disappear in a cloud of smoke, which is impossible. So this NINJA p is still another NINJA, and p1, p2, ..., pr would not be all NINJAS.
