Putting Syaoran aside for now; it is so heartwarming to see Kuromama hugging her son lovingly to comfort him, and her saying “you’re just like your father” is one of the best compliments little Kuro can have because he looks up to his parents so much. He just wants them to be alright and to protect them, just like his family protects everyone else.
Actually that is such an incredible point to make!
Being like his father is the ultimate compliment for Kurogane at this point. It’s everything he strives for. To have his mother tell him that he’s achieving that would be heartwarming under any other circumstance, yet here it becomes crushing instead because you know it’s probably the last time he will ever hear those words.
It gets laced with an extra level of heartbreaking futility when you consider just how seriously he takes it too.
Kuromama isn’t just talking about strength when she compares Kurogane to his father, but in desperation that’s what Kurogane latches onto. He’s always wanted to be strong enough to protect his family, and now he needs it faster. Time is slipping away from him. The faster he gets stronger, the more likely he will be to save his mother from dying.
It’s an awful burden, but it’s one that he takes to heart and dedicates his life to, and he will fail.
