I still believe the second Chainsawman is Yoshida. I bet his Octopus is able to transform him and he does it to make CSM get a good rep.
Remember, it’s been teased like back when Yuko was killed that some phony Chainsaw Man is going around doing whatever. If it was Yoshida, why would he bother transforming before killing her with chainsaws no less? The foreshadowing wouldn’t make any sense.
I feel like it’s a character we already know and that we think of as dead or forgotten.
Kobeni, with the Sloppy Blowjob Devil contract? That one remaining immortal brother that was Halloween’d at the end of the Darkness Devil arc? A-A-A-A-Aki, revived and ready to go at it again?
Could also be a new character but lately we’ve had too much of those... I guess only time will tell! Hopefully in today’s chapter!
An interesting thing to note is that with her mind reading, Yuko as she was murdered was still led to believe that it was at Chainsaw Man’s hands.
I mean, it could be a Devil born from the fear of Chainsaw Man or plain regular chainsaws, it seems to be the most commonly accepted theory.
