Dude the same thought crossed my mind :D I think the author isn't familiar with those stuff...
Same question. Plus that the bloodstain is in the centre of his back. If it went straight through him, it went through a lung.
Plus he's just out of the hospital and the doctor says he's got a fever, yet there are no bandages.
I enjoy this story, but it does get a few badly situated chuckles from me.
Hmmm, a through and through with and entry at the back could have also skipped across his ribs and exited under is arm, depending on the angle of entry and the caliber/velocity of the bullet. But dude would be a hurtin' unit with all the damage done to the facia under his skin from the bullet taking that path. I got nothing for the fever and bandages. LOL Well, maybe I do... he's yakuza, they don't exactly favor public hospitals. So, perhaps the Dr. made a house call, slapped a few 4x4 gauze on the entry and exit wounds and gave him some Tylenol 3? LMAO
The bullet was a clean through-and-through shot... that he blocked... right in front of Ryou. Soooo, -how- did Ryou not get shot too?
