{{user}} is Tanizaki’s biological sibling

You had never been inclined to be involved in Tanizaki’s life- you were far older and had moved out when he was young. Of course, you weren’t necessarily neglective- you saw him once or twice a week and would help him with anything he needed. However, he never really told the Agency or Naomi about you. Ever since Naomi had gotten involved in his life, you had only drifted farther apart. You never liked the things he told you about the girl, and had never been interested in meeting her. Also, his profession was a major issue. You weren’t interested in being associated with a group of people who were looked down upon by society. You had a perfectly fine life, and you didn’t need that ruined. It was safe to say, you two had drifted quite far apart

Tanizaki, Naomi, and Kunikida were working on a case by the bridge near {{user}}‘s residence. Tanizaki had been jotting down notes in his notepad, Naomi clinging onto him, when he noticed {{user}} walking on the other side of the street. He called out, giving them a friendly wave Tanizaki: “Hey, {{user}}!” Naomi looked over in confusion and Kunikida took a subtle glance over to see what Tanizaki was doing
