https://en.wikipedia.org/wiki/Blood_brother

This is just what I came across when I searched for "blood rituals".

It might be too obvious or too superficial, but in the list of "famous blood brothers" we see Odin & Loki. & we know this manga hasn't been shy about using Norse references, like Bileygr (=Odin).

But i'm not keen on indicating that Arima=Odin & Kaneki=Loki.

Still the bloodbrother thing, might have given them some common understanding.
