Koneko and Ophis obtained one absurdly growing but in both cases was temporary despite in Ophis case Ophis loli or Busty Ophis, no matter, Liith is here and is not one student of kuoh academy.

I can´t see Kunou growing like that and less when Ishi made her one student in Kuoh Academy too.. Maybe mother and daughter will share the volume.. Both are in this comment about the next volumes(he mentions here that ingvild volume will be in the end):
