Who or what do you think/like to be the final villain of Chainsaw Man

The final arc of Chainsaw Man is becoming very action packed with a lot of information. We've started getting some revelations about Pochita's past which suggests that the final opponent is a being known as "space". We know that the devil that Denji becomes has been referred to as "Chainsaw man" since the beginning. We also know that Kobeni's devil contract is with the "local devil", who she's apparently afraid of and is hiding their true form.<br><br>Ideally, I would love for the final bad guy to be "space". I love the concept of space as a being, it feels so unique and interesting. It feels like it would be an amazing combination of Denji and Pochita vs the ultimate foe, and an amazing way to bring the story to a close.<br><br>What are your thoughts on the final villain of CSM?
