So I'm just going to say that this is not a novel that I would prefer to read. This fanfic starts off decent but the character power in my opinion is awful. This is Avatar The Last Airbender why would anyone get rid of the bending part. This world is filled with Spirits and so many more crazy things. So now this guy is just a sword user and it's not like there aren't, a hundred thousand stories were there's people that uses a sword. But I guess this one's different because its in avatar I'm sorry I just can't buy into it, no matter how many chapters I read.
This is a pretty good one with as now a slightly op mc. The overall vibe is pretty good but will probably be a split between preferences. And for the other crossover character you introduced it was alright. If it's just a character who will not affect the world background (ie bringing ninjas) then you could have done your own character and make it slightly better. But so far it's good so far.
