It's one of my favourite coats.
Sure,it was nicer to wear a shirt under it,but who has time for these when you have to kill demons who stabbed you and stepped on your pizza? shirtless for fanservice purpose of course
That red leather though. And those straps on his shoulders with shiny pins on it,which gives a more rock feeling.I liked them.
Edit: In fact,I wanted to buy a leather one like this ,but shorter and black.
