Warning! Contains spoilers for Chainsaw Man Chapter 110!
The second part of may be incorporating one of the best elements of the manga's first part in an exciting new way. The second part of the manga has been quite different from what fans initially expected, with series author Tatsuki Fujimoto choosing to feature a new protagonist Asa Mitaka instead of the first part's Denji. But despite being very different from Denji, the manga's latest chapter implies that Asa shares an insidious similarity with him.
Throughout Part 1, Denji would see a vision of a mysterious door that he was warned not to open.
In Chapter 110 Asa has a nightmare about stumbling down a dark alley full of dead chickens.
Given how the chickens multiply as she moves further down the alley, the darkness Asa is heading towards likely represents a repressed memory of her ultimate guilt, just like Denji's door. Given that both of her parents died in a devil attack, she may be repressing a memory of her being partially responsible for their deaths. Or, given that now, it may even be a memory of the War Devil that she doesnt want Asa to see, given that Yoru is literally her darker half and that darkness is concealing the end of the alley.
No matter what lies at the end of the alley, the similarities to Denji's door in the first part are abundantly clear. It remains to be seen whether this Alley dream will appear again, but it would be a shame if . Having a new version of Denji's Door in the second part both ties 's two protagonists closer together and also presents a new mystery for fans to speculate over and theorize about.
