Here's food for thought. Getting shot through the brain makes people remember shit, basically a flow of flashbacks bombarding the conciousness. Yoru remembered a fragment of the Nayuta incident, just the part where she kissed Denji. Asa remembered none of that.

However, since Yoru getting shot in the head is similar to the situation were Nayuta shot Yoru with her chain, from Asa's 3rd person perspective at least, it's possible this might have an effect on Asa and she remembers the Nayuta incident.

After all, Asa was observing everything while Yoru was doggyfied, so if she remembers Nayuta yelling "thief" and everything she saw through Yoru's senses during the ordeal, she might start getting an epiphany.
