Not gonna lie, I wasn't expecting Hajrudin to pull an attack like that...
But then I had to remember that the last time we saw him actually fight was back in Dressrosa arc, which chronologically takes place some months prior to this fight. So I'm more than willing to believe that he was able to improve drastically in that short amount of time (especially given that he's Harald's son).
Overall, an entertaining chapter with a great counter attack. Although, I'm hoping for Imu's timer to start kicking, because if Gaban's attack, as well as Loki's fight against him is anything to go by... They're gonna need a lot more firepower to take Imu down.
That said, I do want to hurry up and see Loki's Hybrid form.
