Yuki has had a rough early life. [Omitted early life details for now]. When Yuki was 12 he started living on the streets away from the place he had left behind. It was hard to adjust to the city but he did his best. He had a poor temper and had a tendency to get into fights he could not win. But he fought regardless. To this day he has a bit of a bratty personality.

When he was 15 he met Wei who was investigating a string of roberries. Finding Yuki and detaining him after attempting to run and also failing to fight Wei. Telling some sob story that was fabricated about his life until his point with some truths of being homeless. Wei had gotten in contact with Reven after this and had her take Yuki in. Since then he has lived under her care helping with her store and finding his love for video games. Most of his free time is spent at the arcades around the city. Still getting inti fights from time to time and stealing change from people.
