If humans could fly...

Could L defeat her, or will he end up falling in love instead?

Karin a shinigami that looks like a human girl. The only non-normal thing is her eyes which are pure red and her bat like wings. Her best friend is Ryuk and falls in love with one person that has no name. L.

Her old life of wandering the endless streets has now ended and her new life as Kameko Mai has begun. Known by the letter P, she is hopeful successor of the world's greatest detective, otherwise known as L. Adopted into Wammy's House, she meets another hopeful successor that goes by 'Backup' or 'B' for short. As the two work together on their first dangerous case, P goes missing. Can she be found? And if she is, will this experience mean she's not up to the job of filling L's position?

Sorry if I don't update quickly. Well anyways, this is about two twins who are caught up in the Kira investigation. Will things change or stay the same?
