If I had to pick anyone, it would be Valeriana from the Celeste Academy series. Sure, she is a little slow in terms of comprehension, and definitely quite dense, but the way she handles being taken to another world so abruptly and adapts, all the while being so relatable(because really, how can anyone handle having to go to another world because you just happened to get attacked-and see- a demon that no one on earth can see, without crying at least once?). I also take inspiration in the way that she handles all the problems that surge the moment she is in Valemnia(the other world). She takes things in stride, but it's also true that she is new to all of this information, so sometimes it's hard to accept for her, but nonetheless she chooses to keep moving forward, and find more about who she is in Valemnia.
