Now that we learnt the fairy's still "alive" in him, I guess he'll have some kind of talk with it or something, his body will stop being unstable and he can use his techniques again ┑( ̄Д  ̄)┍
Honestly I hope it won't be that kind of bullshit explaination but since we already have some kind of "prophecy" ("had he not lost half the body the Gods gave him") the manga will probably go Naruto...
I've never wanted to be wrong that bad
I wonder what he'll do to become stronger so he can defeat that Glenn-f*cker. As he said in the beginning of the manga: He's new body can't handle his skills, so what will he do?!
