Here's what's gonna happen. Denji will awaken his super-hero delusions, and that will once again create a rift between him and Yoru. Just like he attacked Falling only after she claimed she wants to spread terror, right after he was drooling over her fat tits that is, so too will he turn on Yoru because she'll inadvertently spread terror in some way. It might just be a threat on her side, or her beginning to gloat again. He'll also go simping for some new woman, a new pedestrian or otherwise. For one reason or another he'll fuck up Asa. He'll probably chop her up and start eating her limbs, or feeding them to others as some wannabe chef in a restaurant. Enter Kiga-chan, she drains what little vitality is left out of War devil's body and turns her into a maimed, dying wretch.

How do we know something horrible will happen to Asa? Well simple, the story always alternates between arcs that end in a convenient asspull, and arcs that end in a horrifically cruel but realistic tragedy for an innocent character. Now that character is Asa. Example Falling arc (convenient asspull) -> Church arc (inconvenient tragedy). Now it's Aging arc (convenient asspull) -> Famine arc (inconvenient tragedy).

Now betrayed and left for dead by everyone, Asa will finally learn her lesson the hard way, same as Nayuta did before she died. When that happens her final though will be
>I wish I lived just a little bit more selfishly.
Then, as is usual in Part 2, the exact same shit from the start of the story will repeat itself. Someone will save her by claiming her body. Enter picrel.
