Miri is adorable, but that is my biggest gripe with this anime. There is something off-putting about a child character that is written to be always bright and cheerful, even though she had gone through multiple traumatic events in her life. Real children, even those with a normal childhood, show some degree of problematic behaviors, and that doesn't make them less worthy of love.
Might as well forget about the whole assassin thing because the actions and missions are entirely unconvincing. You could replace their jobs with anything and it would not make a whole lot of difference to the plot.
