Isn't there supposed to be a one shot coming out??

it’s a one shot unrelated to chainsaw man. it’s already been uploaded (Look Back)!

Thanks for telling me, I just finished reading the one shot :)

it's a little bit related to csm,
some kid is painting or/ infront of a door and you can clearly see that it's denji's door.

yup sort of i guess, there’s also some fire punch in the manga! ure welcome!
