Scarlet Crimson [Light x Reincarnated OC]

Transmigration into Death Note as Sayu and before the Death Note anime starts? Well, either my brother dies or I die. There is no other option. Warning: this is dark, you have been warned. I do not own Death Note BUT I OWN THIS FANFIC, IF YOU COPY MY LAWYER WILL BE READY. Also, although this is listed as tragedy, it's only like, semi-tragedy!

Also, incest but not really.

I recommend reading on fanfiction, because there, you can see the line breaks that make things much easier to make sense.
