Hey, at least she's the only one who used to have feelings for him.
Everyone else is either too young, not interested, or are already taken.
Not to mention Namie and Varona suck. (He's waaaay above their league)
Though honestly, I really don't ship him with anyone at all. I just can't see him in that situation, like ever.

Why is Namie not on the list? I ship them so hard. I like him and Saki as well through - she is the one who does give a damn about him manipulating her, and even look up to Izaya, which he obviously enjoys a lot - yet goes against him as soon as she feels like it. I dunno, I just think Izaya possibly might want to get Saki's loyalty back for the sake of it. Even through now I guess I am really in the fanon, not actual canon area.
Mikage is really cool, yet she is too much of a straightforward Tomboy.

umm where's Namie?

still kind of weird to me that these two were ever a thing but if he has to be with someone I guess I'll roll with it. They work together.

Mikage at least use to like him though I doubt he'd return the feelings. I can't really see him with anyone.

Imma go with Mikage, even though I stand with her being Ran's wife
