Riyani is an ordinary eight year old girl with an extraordinary older sister, Yokowa. Yokowa is the epitome of perfection: beautiful with a gentle personality, a genius with an IQ of 180, captain of the gymnastics club and not to mention student body vice-president in a prestigious all-girls school. She is Riyani’s pride! Sure she can be quite secretive sometimes like not letting Riyani inside her room but Riyani still adores her older sister nonetheless.
Life was perfect until an accident occurred leading to Yokowa’s death. Depressed Riyani entered Yokowa’s room only to find a secret door leading to the discovery of a doll that looks exactly like her older sister. Upon touching it, the doll came to life.
She is Rikowa and she has no idea what she is. All she knows is her name and her mission, to protect Riyani. Now Riyani must find out about who her older sister really is and why seems to know something that isn’t supposed to exist: sorcery. Not to mention finding out whom Riyani is being protected from.
Now this wouldn’t be too hard if Rikowa is like her perfect older sister, which she isn’t. Rikowa is the exact opposite of Yokowa other than her looks: below average in athletics not to mention being accident prone, naive and seems to be incapable of sitting still for more than 5 minutes. If Riyani didn’t know any better, she would say Rikowa was her clone, not her older sister’s.
Ah! What a trial for an ordinary 8 year old girl!
