Liability (гет)

A canon-divergence AU beginning at the point where Misa is taken into custody as the second Kira and forfeits her Death Note. Light wants to turn himself in, but Rem has decided that Light, and the Death Note, are too dangerous for Misa. Rem forces Light to cut ties with her, hoping she can have a normal life again.
Light breaks up with Misa and continues operating as Kira, leaving Misa alone in L's custody. L, suspecting that Misa might be more powerful than she appears, decides to try to take advantage of Light’s abandonment and befriend Misa, hoping that if he earns her trust, she might turn on Light and help L bring Kira down.
