Natsu is a senior who suffers from sever depression. He burns himself to escape his cruel reality. He suffers from PTSD. Lucy is a new student who also suffers from sever depression. She has multiple personality disorder. Each personality buys a key that they sharpen to create a blade. Each key is used to cut. Both broken. Both lost. But even in despair, they bring each other hope.

Each chapter will contain Yui and one of the Sakamaki brothers. Based mainly on the anime rather than the game or manga. Read with caution as this is for those who are mature and used to these types of stories as it will contain the usual blood, sadistic acts, abuse and sexual situations.
