Nakura is my favorite character from durarara. He only made his cameo once and literally is never important or relevant to the plot in any meaningful way other than to set the stage for Izaya’s story.
So little is known about this weasel of a man that sometimes I come up with nonsense headcanons. To name a few:
If he thinks he won’t get caught he will actively act against Izaya. Even if it’s extremely petty. ie; shit talking him or spreading rumors.
He prays every day that Shizuo will one day put an end to Izaya and release him from his suffering. Amen.
He can’t parkour and is extremely afraid of heights.
Nakura has been a Saika Zombie. It’s unclear when he got cut but it hardly matters as he isn’t even aware of it.
He’s prone to a gambling addiction and can be found straying to casino’s, buying lottery tickets, or oddly enough spending his money on collectible trading cards.
He smokes. He's too stressed not to. Started harmless in highschool, now its a coping method.
