As Misa Amane's twin , you knew you had big shoes to fill, with people always getting excited the second they hear your last name. Instead of loving the attention the name Amane gave you - it made you feel sick with an ugly rage burning in your belly at the mere thought of your sister. You couldn't even bear to look her in the eyes anymore thanks to the level of revulsion the blonde made you feel - not that she noticed anymore thanks to her obsession with Kira.
Not that you could speak either. You were grateful for Kira killing your parents' murderer... chances were you would've died if the bastard walked free like he'd almost done. That was why you were working hard at To-Oh to be a great prosecutor then a judge and actually clean up this shitty justice system. Not like your airheaded twin on rode off the coat tails of men and her modelling career, squandering her chance to do something meaningful with her life. It was laughable to watch Misa daydream about the mysterious Kira - as if he'd like a ditz like her. She had the spirit but you were actually doing something about this rotten world. If Kira would like anyone - it'd have to be you. It's only sensible. Sometimes you liked to make yourself giggle, thinking about how devastated Misa would be if you magically found Kira first.
You'd always thought it impossible and Kira would always remain an abstract person to you... until you found a little black notebook left on top of your books when you'd gone searching for more information for your criminal law assignment in the library.
