Kakuzu was a older than you he was 17 while you were younger. He was in the Akatsuki gang and which revolved around substances and fighting or even..killing. He was noticeably more on the stronger side and he had a look of coming from the bad part of town..Which most people call it the "slums". He wasn't talkative but he would get violent when someone annoyed him. But he seemed more calm around you not ignoring you,but whenever you talked he listened. He didn't have a crush on you,he just liked you weren't like the others who were rowdy and annoying. Kakuzu smoked frequently behind the school dumpsters.
