- Mikado is self-explanatory, in the end I really didn't get just wtf he was trying to do, pulling a gun, shooting Masaomi and then killing himself. Complete nutjob...and I never understood why he didn't get Izaya for messing with his precious Dollars in the first place - he should have known who was going around spreading invitations to hoodlums, but decided to direct his wrath on them, instead of going for the mastermind.
- Masaomi was more emo than anything, although his behavior was justified by all the shit he took from Izaya.
- Anri has an inferiority complex, serving as Mika's "accessory" friend at first and rarely standing up for herself later on. At least she became conscious of her own feelings and desires.
- Shizuo: always angry, always breaking stuff. Yet, for all the people he sent to the hospital, he only got sued once - and that was a framejob! That's what you get for letting him go for so long
- Kasuka is the exact opposite, having a very passive face...but his personality is actually pretty standard and he learns through his work, so he's cool.
- Izaya is a self-destructive man who wishes for the world to end. Nothing truly benefits him (except Shizuo's misfortune), but he revels in others' misfortune as if he hit the jackpot, when in fact he's just making more and more enemies for himself. For a smart guy, he sure is stupid.
- Mika, Seiji and Namie: One is a super-stalker, the other is a materialist, with eyes only for a head and the latter is a brocon slave.
- Izaya's sisters: probably just cute little trolls trying to have fun...dangerous kinds of fun.
- Mikage: I seriously don't know what to make of her. Izaya did
bad stuff to her, but she proceeds to rescue him AND become his personal bodyguard. Dafuq!?
- Walker & Erika: reality escapists (walker is also clearly an arsonist).
- Togusa: idol fanatic, to the point of wanting to kill Ruri's stalker himself.
- Shinra: obsessed with Celty's body, courtesy of Shingen. Definitely a dick for holding Celty down to him, he's basically doing with her body what everyone else did with her head.
- Samya & Dennis: While sober and the voice of reason for the most part, they
did use military-grade equipment right in the middle of the city. WHY ARE THEY NOT IN JAIL YET!?
- Niekawa x Nasujima: OTP of the series, best ending unlocked. I imagine Nasujima got Saika'd and they just kept grinding on each other's blades forever.
- Aoba and Ran: crazy people be crazy, especially the hammer-wielding Ran. I still wonder on what terms he got out of jail so quickly and who was in charge of his probation (assuming he appeared just as his sentence concluded). Aoba loves Mikado's crazy side, that automatically makes him one of
them.
- Varona: goes from down-to-earth assassin to inexplicable Shizuo tsundere.
