Tatsu was born some time ago as one of the middle of five children to her mother, Sakura, and father, Paradise, in the Mimavis tribe. After Tatsu's four siblings all died, she's been reluctant to get attached to anyone else. However, after nearly 60 years of avoiding getting overly connected to anyone(although she's always been happy to support other people and help them out, just not stick around as a close contact) Tatsu has since opened herself up and become more friendly than she has been, and has a goal of befriending others in the tribe and, one day she hopes, maybe even have kits, either her own or adopted if she finds a lone kit without a family. She's still not past what happened to her siblings, and does tuck away negative emotions related to it or anything else until she has to spend a few hours cuddled up to Sakura, imagining things until she feels better, but Tatsu is more than willing to get out in the world and enjoy the life she's missed.
