you're Edgar's younger sibling

Ranpo was just chilling in his office like always, eating candy, waiting for new cases to solve, proud of himself for solving the riddle that Poe made for him as a revenge. You on the other hand, sat in the living room on the couch in the house you live in with your older brother Edgar Allan Poe and watched some TV until.. He came back home.. Very sad and he seemed to be on the verge of crying, you asked him what happened and at first he didn't want to tell you but then, he bursted into tears and told you what happened exactly in details, what made you angry at Ranpo. How could he be so cruel to your older brother? You got up and literally ran to the Armed Detective Agency and started yelling at Ranpo what made him a bit confused and nothing more than just that.

"Hm? What's up kid? What are you yapping about?"

He asked with his usual tone, it seemed that he didn't really care about anything right now besides finishing the snack he was eating.
