WARNING, SPOILERS FOR BOTH WN AND LN FOLLOW!said it once will say it again, pickpocket situation was covered a LOT better here than the Web Novel. Thank FUCK we dont have to worry about a bajilion chapters of akira chasing a petty pickpocket just to fuckin kill her (a'overreaction? I dont know the meaning of such a word!"- WN Akira probably)
Some clarification is required: There wasn't 'bajillion chapters of Akira chasing a petty pickpocket'.
Resolution happened much later in WN because her story was intertwined with other story arcs (Yonozuka station ruins that manga covers right now, Bounty monsters hunt, Mihazono ruins - Seranthal building exploration, attack on Sheryl's relic shop).
So while it took almost 100 chapters from theft till the Ezont estate fight and Alna's death, majority of story wasn't about her.
(RW LN tends to package the whole stories neatly in one volume so I guess a long running 'parallel' story that would span 4+ books from later chapters of LN Vol.2 part 2 till the end of Vol.5 wasn't desirable, among other things.)
As for the overreaction part, that's what happens in LN/manga.
In WN Akira was obviously very pissed after he was robbed but he stayed calm enough to listen to Alpha and didn't start shooting while running down the streets like a madman.
After running into Katsuya and his team, Akira realized he's outnumbered and outgunned and backed off after some prompting from Alpha despite Katsuya's mocking (Yumina didn't intervene, only scolded Katsuya after Akira left).
In LN/manga he went berserk, guns blazing, despite not having augmented suit and Alpha's support.
Ignored Alpha's advice and after confronting Katsuya's group and getting mocked, his brain shut down and he reached for his rifle.
Only survived because LN Yumina intervened.
If throwing own life away in a fit of rage isn't a huge overreaction then I don't know what is.
Certainly not killing someone who stole 100K Aurum from him.
That's kind of typical punishment for such deed in slums:
'he did not feel like going with the usually expected punishment either, which was just a simple bullet in the head'
( LN Vol.2 part 2 chapter 69 - A Matter of Perspective. )
People in slums kill each other for much less.
Manga being abridged version of LN skipped that story, but in LN and WN Akira got jumped by 5 other armed kids trying to rob him after he got his first reward from Hunter office (300 Aurum) and he only managed to survive because of his stock of old world medicine. (WN chapter 5, LN Vol.2 part 2 chapter 67 - in form of a flashback)
Finally I can't agree with 'pickpocket situation was covered a LOT better here than the Web Novel'.
It's not much of an argument that it's better because it got resolved quickly or that Akira 'just' killing her in the end was an overreaction, because it really wasn't.
Also, big gang war from LN Vol.5 can't hold a candle to WN final showdown in Ezont mansion and replacement stories covering for the shorter pickpocket arc are less than stellar, and that's putting it mildly.
There's a bunch of things LN did better than WN, but the pickpocket story wasn't one of them.
