Which of these characters would be the best roommate?

Lunge most of the time would be out and even in room doesn't bother or much socialize with you
Pros - like living Alone
Cons - Boaring

Johan and Roberto are out they will probably troumatize or Kill you

Eva one is unpredictable , Coz throughout the series she has gone much character development so the question is Eva from which Part
Pros - Money and fun ( beginning )
Crazy and Friends with benefits ^^ (mid)
Bestie and chill ( End )
Cons - Crazy and challenging

I'm all in, I can fix her >⁠.⁠<

Johan is the best option. Like dude's pretty chill and sweet when you are not his target.

@JunimoGreen If I know him too well, I doubt he'll do something so direct as killing me. He does most of the killing using other people, so the chances are even lower.

@JunimoGreen all people Johann has used have some sort of connection to criminal activities. So I'll be used mostly as an alibi for his innocent life.

As you can see, Johann barely has any concrete evidence regarding his crimes. One of the biggest reasons behind this is he not only interacted with most people normally, he involved very specific people in core risky tasks.

The biggest perk of having Johan as a roommate is that his stay is likely to be very... temporary.

I agree with Tenma, but also Johan tbh. he seems like someone who cleans after himself ... well as long as he doesn´t clean my body away :D
