I want to start watching the anime at what I think is 8 or so episodes released and even though I'm waiting for the first season to end to watch them all, I'll possibly start reading the manga.
I'm fascinated by the design of Kaiju N°8 and I think it's great how it looks in its original format, your post convinced me to read the manga first and then get into the anime; I always do the opposite.
The manga really caught me, I am also one of those people who watches the anime and then the manga but this one made me totally forget that the anime existed 🤣
