Idk Elbaf's War God was referenced the very arc where the readers were introduced to giants. Davy Jones is much contrived as he was clearly supposed to be a joke character pre-ts looking at Oda drawing of him in a SBS
Fair enough, I just find it pretty hard to care when we know nothing about him or how he relates to the story.
Like.... he rivaled Nika, which is okay but...:
I don't really know who Nika even is(?)
Was it a friendly rivalry, which is why Elbaf worships Nika?
How does Elbaf generally view him? Presumably, Harald would had a grandparent or something who knew him(or maybe he is Lokis ancestor? I don't remember), and strongly dislikes John Elbaf, but we get nothing.
When we get the dots connected together, I think some of this stuff will work a bit better, but as long as all we have is vague references to 4 Gods, it's kind of snooze worthy.
