chainsaw man

Whilst the series "Chainsaw Man" has much in common with other shounen action series, it also appears to be trying to make some sort of spiritual point. The frequent invocation of devils and the Four Horsemen, for instance, seems to be drawn from Christian theology. It is also possible to read Denji as a Christ figure (whose friendship with others causes them to become better versions of themselves) and Makima as a Satanic figure (who wants to bend the entire world to her will).

On the other hand, Christianity does not appear to be the only influence in "Chainsaw Man." For instance, Denji may be less a Christ figure per se than a generic "savior" figure, similar to Neo from "The Matrix," who has his roots in multiple religious traditions. Moreover, there are actually some interesting parallels between Makima and the way certain atheists understand the God of the Bible: namely, as a sort of controlling, wicked stepfather.

What spiritual dimensions can be found in the characters and setting of "Chainsaw Man?" Is there any influence of traditional Japanese spirituality, such as Shintoism or Buddhism, and if so, what does it consist of? Are any of the spiritual references in the series deliberate, or are they purely aesthetic?
