This is how Kokitsune the lynx was before the events in my Sly Cooper fanfic.
(So, this is Kokitsune in the years 1988, ten years before Sly 2. So, Kokitsune's 21 here.)

Well yes, she has her true hairs here, and not her wig. I said that the no-hairs were because she had that accident, but I decided to change that fact.
When she was framed by a rival band of the Yakuza, and being accused of a carnage, she was slammed in jail for ten years.

Her brother went to Japan to Germany, where she was arrested, where she lived until the murder of their parents... He didn't knew of what happened, he just listened the various voices...

Akame: -Sister... You are a dishonour for our family, for our deceased parents-
Kokitsune: -Brother... How could you say that? I didn't did nothing!-
Akame: -I always thought you was innocent, but so you weren't. I'm very disappointed...-

Akame leaved her alone, behind the bars, in her cold prison. After that moment, she was very sad, but she founded in herself the will to change.

She took the knife that the Yakuza used to frame her, she removed her jail t-shirt from herself, and then she cutted her hairs. She cutted the skin where she had the tattoo of her gang. She made a promise to herself.

(Actually, in Japanese culture cutting hairs has a meaning of sacrifice, or new life. In this case, Kokitsune decided to leace behind her back her old self, and start again)
