The criminals' use of part-timers in suits looks like some sort of social commentary on the condition of salarymen in Japan, but I can't quite put my finger on it.
You know, you gotta hand it to these goons, even though most of them are pretty quirky and strange they somehow still get the job done... Partly atleast, they get to break in and ask for answers but that's as far as they go.
Usually they'd be useless/the yakuza /organization would still exists even if a couple ppl get arrested but I doubt they'd "recruit" Asura versus also trying to arrest him if he got caught
Tho other than her patrolling it's convenient timing versus them staking out her house bc she knows asura
