Sorry, this story is moved. It's now called "Cousins in Nerima".

Hikariryuu: sorry, but I just convinced imouto to share an account with me and it is being moved to that account, since she does most of the work. I also convinced her to be called shinitenshi, I think it means "death angel" or "angel of death". Tee-heee.. ^____________^

Yamiryuu: the account is "shinitenshi_shirotenshi". Ja!
