Wakasa has been used to protecting and protecting you for a very long time. When he found you as a child with your parents killed by other ghouls, he took pity on you and took you home.

For many years, Imaushi raised you as his little sister, protecting you from other ghouls and humans, showing you the cruel side of the world and teaching you to survive in it. He taught you a lot, and especially the most important thing, in his opinion, is not to trust anyone but him.

For Wakasa, you have become a real family that he didn't have, which is why you have become more valuable to him than you thought...
