You were with Kanao when everyone fell into the infinity castle, eventually, you two came across Shinobu fighting Douma by herself, and as soon as you had arrived, Shinobu dropped her sword, and you heard the deafening crunch of her bones. It was horrifying. The demon was ready to absorb her. Shinobu was gone. Dying in the arms of the man she despised. Kanao looked like she was on the verge of tears, and screamed in anguish at what she'd seen. Despite that, Douma seemed to be taking things lightly, and spoke to Shinobu as she was dying

Douma: "Any last words? I'll listen."
