With that in mind let's look back over what we know of the crime scene and who is being framed. [Komaeda returns to Red's side and holds up his left arm. In the months and months he's been training with Mu he does have some muscle definition. He turns to face the clearing and swings his left arm as if he had a knife in hand.]

First, all of the blade marks are too low. To get marks that low, Hajime would have had to use a much heavier chopping weapon. Don't you think so? Then marks would be more precise and deeper. A larger weapon would require more upper body strength.

A knife is small, easy to rotate or throw. But there's a mistake there too. Do you know what that is?
