The manga of Part 2 isn't done yet but it's been done in the light novel and web novel for years so plenty of people can read it. On top of that once season three of the anime airs all of Part 2 will be adapted to anime so now anime watches can also read this.
They're adapting three Parts at once (Part 4 began last December) because it takes a long time to adapt the manga and the series is very long. The first chapter of Part 1 came out in October 2015 and here we are over five years later and Suzuka hasn't even first adapting volume 5 of the novel yet. The series is going to be 33 volumes which would take forever to complete. Even if they only adapt Part 1-4 that brings us to 21 volumes which would still take forever to finish. |
