YUI'S SISTER (Diabolik Lovers X Reader) [DISCONTINUED]

Yui and y/n are sisters but even tho they are sisters they are quite different from each other.

y/n is a badass female who is not afraid to stand up for herself and her loved ones.

She is like a mother to yui and loves her enormously

she is the one who always protects yui from harm and she will keep doing it until she takes her last breath.
