He gives that handicap to himself since he is a master. How can you not notice this. Tsk tsk.
If you havent read this stuff you really should.
I know
It will turn dark later.
It's based on a LN which I am up-to-date.
He will become more badass with long hair when he will embark on a journey to seek revenge for the death of one of his closest ally. What made this revenge seeking more brutal is that everytime he will kill, he will cut a specific body part to be presented on the grave of his friend.
Why? Because he only received the fingers of his friend so when he buried the friend he swore that he will complete the body of his friend by the blood and bones of those who killed him/her.
He will become emotionless and will kill without showing any remorse.
Okay my headcannon is over. Peace out ✌️
