NO I DO NOT OWN DEATH NOTE OR HARRY POTTER AND IM GRUMPY BECAUSE IM TIRED SO LEAVE ME ALO-zzzzzzzzz
Umbridge's PoV
I pick the book off of the floor. 'Death Note'. Flipping through it I find nothing. Just smooth, white pages of blankness staring boldly back at me, unabashed by my presence. Until I reach the back, that is. I scan the instructions. Interesting. A little slip of white paper floats into my mind. 'Dumbledore's Army'. Wouldn't it be nice to have a serious of completely unrelated accidents leading to the tragic demise of every person on that list? So satisfying, Dolores the victor, Potter the ghost.
But I have to disguise it. After all, if it's found I could be in serious trouble if they trace it back to me! I glance furtively around before tapping it gently with my wand. The book changes to a cracked, maroon, leather-bound planner with the gold-embellished words 'planner'.
I open up the yellowed pages, faintly scored with horizontal lines. Every day is marked on a new page from the beginning of the year and at the end of the day is a section marked detention. All I need to do is scribble the names of those miscreants into the detention slots and allocate them detention times and there'll be no evidence pointing to me. I hug my discovery to my chest with glee. I've won!
Nobody's PoV
As Umbridge hurried around the corner towards her office, Hermione Granger appeared from under the invisibility cloak, holding a camera. 'Bingo' she smirked. All she had to do now was follow Umbridge and record her writing down the names. That added to the evidence of her use of the blood quill as a punishment and Umbridge would be fired.
Hermione had never known a homework planner to be so useful! I guess anime+charms=complete and utter genius.
Meanwhile, up above Ryuk watched the events taking place. He was planning to drop his note somewhere soon, but he couldn't help but stop and laugh at the young woman's cunning and absolute genius. Wow.
