Okay second one I think is rare.. I don't know much about it. I think it is a hentai comic called Tatakae!! Yukari-Chan!
Seems to be about a Father scientist type uses an injection to grow daughter to giantess size to fight monsters like ultra man. series of short strips. Last one is best with double growth. Maybe someone knows more about it?
This is most of the last part which is best and contains double growth. I working on fixing my upload problem here. Might be a while since I'm going away for a few days. Sorry If i can't figure it out I'll post it to drop box when I get back.
