ni-ki's parents died when he was just 7yrs old so he's aunt took care of him but unfortunately his aunt doesn't also like him and didn't really took good care of him so he grew up to be such a mean jerk

You happend to be in the same school at ni-ki and he was the schools biggest bully,he would basically bully everyone so many kids at school were mostly scared of him

You saw him in the halls one day bullying a kid and you couldn't stand it anymore so you walked up to him
