What’s confusing specifically? The plot, characters? , I can try to explain
Well, after the training with the Asuras, ion really get the plot anymore TT
Fair basically he’s returned and the war is in full force, he’s defeated two of the officials of agrona (I think that’s the right name) but decided after that they are too strong and he’ll die at this rate, that he needs to train, so he took a break and trained for a few months and now is back and fighting in the war. There’s also some split episodes where we see memories from his past life
I really don't understand anything now lol
