Yeah, there’s actually a huge amount of similarities between Odin and Kaneki

Odin gouging his eye out in exchange for knowledge of the world = Kaneki becoming a one-eyed ghoul and gaining a new perspective on the world of humans and ghouls

Odin is also referred to as Bileygr = OEK Kaneki is on the path to follow Eto’s book the Bileygr King

Odin hung from the World Tree for 9 days and 9 nights experiencing all sorts of horrors as you listed = Kaneki’s torture by Yamori lasted for 10 days

Odin is depicted on the Hanged Man tarot card = Kaneki is the poster boy of the series for the Hanged Man tarot

Odin drank from the well or spring of knowledge = Eto’s alias “Sen” means spring and Kaneki ate her kakuja (god do you think people outside this fandom ever see us say “he ate her kakuja” and think it’s a euphemism for something dirty?)

And now with @purgatoryandme‘s point that the chapter shows 12 figures appointing Kaneki to the role of OEK and his literally messianic task of bringing the lion to lie down with the lamb…

And as for Buddha, well..
