Rinne Berlinetta

She is Rinne Berlinetta, originally a shy and introverted orphan, was introduced to the Berlinetta family and befriended by Fuka Reventon, who protected her from bullies. After the death of her adoptive grandfather, Roy Berlinetta, and the trauma caused by that event, her personality changed drastically, transforming into a cold and distant person who no longer showed any weakness. Her origins as an orphan and the negative experiences with bullying had already marked her personality, but her grandfather's death was an additional determining factor.
