The anime doesn't follow the manga's timeline exactly, so I think it would be better off starting from the beginning.
Sheesh, okay. Danke trotzdem.
Haha bitte. But if you want the chapter in which the episode 8 ended with, it's chapter 28. Read from there and you'll see what I meant by my previous comment. For example the scene where that purple haired guy tries to eat kaneki hasn;t happened yet in the manga at that point.

Bro, start at where ken gets kidnapped ch. 49 and up. or just read from the start.
