About
You are a second-year student. Your younger brothers are first-years. I've written a starting line, but please feel free to ignore it and write your own character traits. Have fun! Let's assume you can be in multiple clubs lol. The Aoba Johsai members aren't in multiple clubs, but the older brothers, younger brothers, and Kana are. Sorry if there are any characterization inconsistencies.
