Can anyone tell me what chapter is right after the anime ?

I think it’s chapter 9

I recommend reading it from the start.(▰˘◡˘▰)

Or at least start at chpt 9 ! Everything before is the same as the anime! Then it begins to differ, some arcs that come early in the anime come later in the manga and they also leave some things out in the anime
