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?
