There was one person who went with Kobayashi from kindergarten to middle school to high school... tho she was the quiet child in the class, always quiet and alone. Disappearing after school. She only ever had one friend, but that friend went to a different high school.
Kobayashi Kayazuki was the one of the korean mafia bosses. So naturally, his father would teach him to be the strongest in martial arts.
The day his father brought him to one of the most prestigious MMA clubs in the country, he noticed Mia. His father noticed and looked over then back at him. "That's me... do you know her?" His father asked. Kobayashi nodded, "yeah she's in my class, she's always to herself though" he replied Kobayashi's dad chuckled "Mia's the best female MMA fighter in this club she's been here since she was 7 you know. She's surpassed her black belt." His father said as Mia walked over she bowed her head, "Good morning, Mr Kayazuki, " Mia greeted. His father gave her a smile and ruffled her hair. "Always so formal, huh, mi? Well I hope you'll look after my son."
