Yay for slime diaries giving a different perspective on the events.
Shiori's impact is probably wider than many think, after all if you then include all the monsters who moved into living together with people and the bonds that are forming because of Rurii and Shiori... no to mention it's just getting started for some things. The preserved food the adventurer business is starting up, the search magic, some new revelations about combined magic, and even some changes in terms of education are really just at the starting line. Toss in the changes that her cuisine and the deepening of trade/interaction with the eastern nation.
I can't wait for Shiori to meet with Oliver and realize he was the "lost" man from back then. I wonder if it'll come up that she and Rurii was the inspiration to get a slime of his own.
