'My older sister is so pretty today as well!'

'Those no good bastards, how dare you covet our family's eldest daughter?!'

It seems this so-called younger sister of mine is as energetic as always. Back then, this silly girl had such outlandish thoughts...so amusing and never dull. Her knowledge is almost prophetic...I can't exactly get rid of her just yet. Not when I want to take revenge for the injustice for my mother, my father...and my actual little sister who died long ago.

This so-called younger sister...I do not dislike you, but I cannot find it in myself to love you...you who have stolen the body of my true younger sister...I will ensure your life....because that life is what keeps the body of my most beloved little sister alive...the last of my blood, the reason why I live.
