After years of barely talking to her big brother, Uiha suddenly wakes up to find that she has a body-double, who is both her copy and her complete opposite.

However by chapter 105, things take a tremendous down hill imo. And all the cliches you can think of, start to seemingly occur.
The chapter 105 and afterwards was honestly so bizzarre, like the twin has another personailty whihc is a fallen angel, the twin goes away and they forget about her. Then they learn about her again and after 15 years she is able to come back and the demon is like ok lmao. Like if they remov3d the demon and made her live with them throughout the whole time rather than dissapearing and the reappearing after 15 years,i would have loved this manga really much, but mn those last chapter after 100 really took a nosedive in regards to asking what direction this manga is going
Overall good mnga
But
Apparently, FL and ML aren't blood related...but they've lived together as brother and sister, so it's still gross....
