So here's what might happen. Yoru refused to kill Denji to save herself, yes? Then she died immediately after. From Denji's perspective this would remind him of Power's death, where Powy had a chance to save herself by handing him over to Makima, but she changed her mind in seconds ran with his body instead.

From Denji's perspective Yoru is Powy, the devil who loves him and refused to hand him over to die. Asa, who hates Yoru and wants to finish her off, is of curse the bad guy/Makima in Tardji's eyes. Powy flashback happens, followed by a flashgone.

Thoughts?
