This one received a pretty hefty overhaul to make it attune more towards a servant. The obvious choice was Emiya, but Tamamo, Jack, and Nursery Rhyme still get plenty of screen time to help make the archer’s day a little more rewarding.
His presence wasn’t established as well before, which is why I assume some thought he was OOC. Thanks to his interlude, which shows that he was teaching the master the basics (in game), he was one of the first within Chaldea. The start point of Fragments is just after America four months later, which means he’s had that much time to adapt to his new environment.
To better explain the reasoning for his changes, I introduced the driving force at the very beginning, that many should have already guessed: His promise to Rin at the end of UBW Route. Take that, the memories he now has access to since Fate System works differently, and the considerable amount of time and allies… yes, his newfound outlook is very much plausible.
I gave further backstory in his relation with Irisviel and Arturia, along with a small introduction to Memorial Essences. It does not displace the complete design explanation in Kiritsugu’s fragment, which shows a visual example of how it’s done, and explains a new Noble Phantasm can arrive to unlock a plausible class change.
The core of the original was left almost entirely intact as planned, and makes up the latter half of the fragment. Yes, this means the cute interactions with the two child servants have all made it through the revision just fine; The kitchen is full of extra sweetness as originally intended. It helps it acted as the destabilizing event to his otherwise mundane routine, and allows him some small glimpses into how others have also progressed.
A trifecta of examples is now completed to better showcase the range of Fragments. Jeanne’s was a story of a servant’s first steps in appreciating a new environment. Nobunaga shows numerous interactions with different servants for a personally driven purpose (short or long term). Emiya is from the view of a long-time veteran, and depicts how greatly some have changed over time. These are three universal concepts that appear often in the work, so setting the foundation that they’ll appear should provide new readers with an idea on what to expect.
