Tragedy: Aguri sacrificed herself to save him from the scientists. To Yukiko, it felt as if Korosensei had driven her sister to suicide, breaking her psyche with his experiments. This planted the seed of revenge within her.

Existential Collapse: Realizing that her years of revenge were based on a delusion, she is completely devastated. She screams, "Kaede Kayano never existed! She was just an empty vessel!"
