For this one I think I’ll have to go with Irisiviel von Einzbern from Fate/Zero.
I’ve always admired her kind and gentle nature despite the life she had and the events she goes through. She’s also a very strong person, if you ask me. Iriasviel’s always been there for and supported Kiritsugu on his journey and she stood by her convictions until the very end.
As always, thanks for stopping by ^^.
