Monster! Ore no Imouto ga Konna ni Kawaii Wake ga Nai ( I don't know any Japanese but i think it translates to: "giving my sister and her two friends, treats on halloween")
Our parents had two sets of twins: two boys, and then two girls. Because my brother and I were older, friends and family always thought we were mean to our sisters and bullying them, but in reality that couldn't be further from the truth.
