It's also quite easy to just give the police the adress of the establishment and have them take them all in custody. Problem solved. You don't even have to run away and they don't even need to know who gave the tip.Karen turns around to face me. "Don't go getting any ideas. If you run, they'll find you, believe me. Not too hard to spot someone as burnt up as you in broad daylight."
Girl, you're in Sendai, which is in Japan, which has a working judicial system, and Hanako is not really hard to identify...Karen shakes her head, dashing my hopes immediately. "Kid, we're in Sendai. There are over a million people here. I'm sorry but there's just no chance."
Plus that Café doesn't seem to make much effort to be discreet. If Hanako went missing, I'd expect the cops to show up there within a week if that long.
For your story concept to work you'd have to change the setting from Japan to some Noir-world where every cop is corrupt, like maybe Sin City.
