User blog comment:AquilaeAltair/OnS Theories. Seventeenth Theory - The 7 seraphs of the end. Is it possible that new Seraphs can exist or are they in front of us?/@comment-33903590-20190329123033

I agree with you, I do not think that new seraph is awakened. Unless one comes up with the idea that Yoichi or Shiho could awaken the drugs as with Yu. But it is far too unlikely. It does not fit in the scheme.
