I know people joke about "why should this be TS or isekai?", but how would you explain Touri's general attitude otherwise?
Just imagine a non-isekai'd war orphan girl having the caution and spatial awareness of an avid FPS shooter, her vulnerability from her lack of self awareness as a girl...
That's my immediate thought as well. Dad could've just grabbed his hand last second to look even cooler, but plot dictates his face needs to be injured so prince will meet him.
