Can anyone confirm or deny if Tokyo Ghoul:re, the 3rd season of the anime is canon or not? It seems like a major step after the events of the first and second seasons so I'm pretty darn bewildered by all the new characters
Yes, Tokyo Ghoul:re is canon
If you take a look in the wiki you can see that Tokyo Ghoul:re (東京喰種トーキョーグール:re, Tōkyō Gūru:re) is a sequel to the Japanese manga series Tokyo Ghoul written and illustrated by Sui Ishida.
And yes, Tokyo Ghoul:re picked up 2 years after the events that ended Tokyo Ghoul
