Trigun Maximum Vol. 10: Wolfwood
By Yasuhiro Nightow

Wolfwood's feeling his wounds, but also numbing to the point of wondering if he's already dead. Master C states how needlessly stubborn Wolfwood is being by clinging to Vash saving everyone when it's more likely the end would come in a few days. Wolfwood admits he'd left Vash in the lurch by coming to fight him and Wolfwood, as well, and to prepare to die 1st. Master C sticks his huge sword just enough into Wolfwood, he then dealing with the g/ma and orphan kids who refused to leave her side despite her telling them to flee.
Master C mocks how tight knit they are, and why Wolfwood is trying to protect them, he dragging him forward making note how his regenerative cells'd changed his appearance from how they'd known him from before. G/ma recognizes him, and says how sad she is he hadn't listened to her about dealing with problems alone, but happy he'd returned to them in the end. Wolfwood agrees he'd made a mistake by waiting, and had met someone dumber than himself who'd have helped him if he'd sense to ask. Master C decides this unloading had reached its end, and is ready to kill Wolfwood, Vash coming to his rescue, confirming Wolfwood'd made a true buddy!
Wolfwood can't imagine why Vash'd come so far like a dummy, as Razlo trips out due to Vash dodging all his cross guns bullets. Razlo bets he can't hold out for his next blasts of 10 seconds as Wolfwood is quickly healing against Master C's shots, he shocked to learn Wolfwood had double dosed himself which should make him implode. Razlo starts yelling Master C's name, when he's engulfed in explosions, Vash instructing G/ma and kids to find shelter indoors. When Razlo sees the 2 men fight in tandem seamlessly, and fluidly, he wonders how often they must fight in high stress.
The duo quibble like kids as Wolfwood insults Vash's looks finally matching his age, but admits to having overdone it to Vash's hanging head. Wolfwood then states Vash should sit this out for him to handle solo, but he doesn't agree. Soon though, Vash gets why Wolfwood feels he must handle their enemy alone, like Vash felt toward Knives. Razlo is ready to take the duo out together as an honor to Master C, threatening to make Wolfwood's head vanish.
When Wolfwood attacks, Razlo is let down by his lack of threatening moves. Razlo returns attack, and Wolfwood also shoots back in unison with him, and as they continue, Razlo senses Wolfwood is getting quicker until he's defeated. A soppy skelly is left to wonder how his regeneration isn't starting, Wolfwood taking the last punch to the skull before killing Razlo. Then, Livio realizes he's going to truly live normally, which officially kills Razlo.
Wolfwood acknowledges "Crybaby Livio" finally has returned. Flashback to Nicholas deciding to leave the orphanage and getting a warm send off and always welcomed back. Present, Wolfwood asks g/ma to not let the kids know it's actually him if shit goes sideways. Then, he has a seat with Vash and they share a drink, Wolfwood almost finishing his confession of regret for insulting Vash's smile being lifeless.
Next, Livio-presumably-looking like Razlo goes inside a bar to ask Vash where Wolfwood is, he confirming he's dead and buried. He then sees Vash's hair is more streaked black, realizing he hadn't heard thunder earlier. Vash invites Livio to eat, and the 2 eat all day, and before splitting up, Vash states of chasing after the ship taking off soon.
Cute death, let's see where Vash now takes us, ey?
