Life.1, when they return from Heaven and meet Irina's dad, and he reveals the technology of the special room for Irina and Ise; while the girls are admiring the room, Azazel and Ise have this conversation.(Untranslated as of now)

It's a pretty huge development, if you ask me, for this to be direcly pointed out to Ise. Really looking forward to reading that conversation.
