It's called a "thug", and they're used to collect money. They usually only cause trouble to the debtors, so they don't need to be outstanding individuals lol
I wonder why Sadaku is not shown even once, he's right there even if he lost, even when they're talking about him... It's probably because he lost both the match and any dramatic expressions he could have made.
Ikr??
Probably read it on the technology news, they tend to make science fiction look possible to attract engagement.
In any case, the drama works, kinda.
I don't think there's that many rich people who behaves like that... How a person who's willing to waste money like that earns that kind of money? Even if they are criminals, they can't be that resourceful to not get caught in the first place.
Seriously, if someone is that physically capable, they would be making cash or being the very bosses of crime themselves. It's like that guy is a different species entirety, it doesn't even make sense.
Seems like the author aims to introduce as many dramatic expressions as possible at this point. It kinda works, but I think it's a hit or miss, specially if you don't buy the drama or the character's motivations.
