Hesse, the last robin who was responsible for the annihilation of his family, took the appearance of a young child and hid under the pseudonym "Shrike". Akabane, owned by his clan, was slaughtered by greed because he could reverse life and death. As a survivor, she was briefly saved by the warmth of the innocent and disabled Shan Guiyu.
But Yu's tragic death tore apart the false tranquility - the murderer tortured her to take away the guardian feather she gave to Yu. This is exactly the same as the tragedy that led to the extinction of the robin in ancient times. After seeing the corpse of his best friend, the remaining compassion in Hesse's heart was completely burned away.
"Compassion is dead, only shrike remains."
Intention: The process of coming to terms with the past
