From the beginning

A mysterious girl who roams around to try and seek for her purpose. Everyone calls her tiga which no one knows why but they are either too scared to ask or they don't even bother to. Tiga (AKA the mysterious girl) had a tragic accident when she was 7 years old. One day when she was at school her parents were at home from work and were killed by the tichitama-ken clan because they tried to run away after stealing their money. When tiga got home from school she screamed and cried. And ever since that day everyone thought she killed her parents and the clan is after her so she is on the run.
