Mouse (A DeathNote Fanfic)

Her parents died from a car crash when she was only 6, since her older sister was traveling at the time, she wasn't there to claim her as her sister. So, Mouse was sent to an Orphanage. She was sent Wammy's, where she met her best friends. Once her sister returned, she checked on the girl, but she was reluctant to leave her new friends. So they weren't aware that Mouse had an older sister, who was old enough to raise her. They were never told. No one was.
