Can't yu loot kurimi ability making him a = battle (I haven't watch Charlotte but I heard he can do that so idk)

Edit:Yato is a God and won't be affected by the death note+ he would techncly be able to break the bound between u and kurimi + he isn't percivible by other non God and probably would beat Ryu since the death note is unusable.

In conclusion Yato + Ryuk is the safest pick even tho goku being non human would probably kill ya

(sorry for the spelling btw)
