Shiro's backstory idea/brainstorm (Patreon)

   (past) At a young age, her parents were poor in a part of Japan with a low economy. She had a special doll, from her childhood, called emi( meaning beautiful blessing ). She had the doll but left it home in hopes of returning since she knew her parents wouldn't leave home. her parents gave her to the assassination program in hopes she would help people and get a good job to come home with money. they told her not to lose herself and to stay strong. not too long after she left the village was attacked and burned, her parents died in the fire but protected her doll.

( current time/future episodes ) In travel with Taoko, Shibuyaki, Karma, and Sakura ( to Sakura base ) they come across her village. She cries at the site this is the first time she uses her magic powers( she kind of has an awakening even though yes she has been studying she could only do small things without her control.). She uses her magic to reenact the scene of what happened to gain closure. they then leave shocked, and she starts to practice magic more, and she grabs her doll after leaving. after they made it to the base. she unintentionally steals karma's life source and is almost forced out before they find out karma can be reincarnated and revived.

I would have the future FUTURE of her story but that would be spoiling either way here's just a bit of info about her back story and going into the current timeline.
