At one of the CSS examination today, we heard about Hajime's shoulder joint.
It was told that already the gap between bones of his shoulder joint
was almost 1inch.
Usually when the gap is wide like this, it causes a lot of pain. This
is cured with an operation, but Hajime cannot take it. Now, Hajime
does not feel the pain that much. Yet he needs to use a sling to put
his arm in.
Now because he does not have muscle on his left shoulder and arm, and
what Hajime can do is just hang his arm loose. The weight of an arm is
actually greatly heavy. Because of the weight it makes gap between
bones of his shoulder.
