Diabolik lovers Fanfic [UNDER EDITING]

You once made a promise that was meant to last forever.

"You promise?"
"I promise."

Nothing more than words between children who believed nothing could break them apart.

As a child, you were close to the Sakamaki brothers, bound to them by something deeper than friendship and too young to understand what it truly meant. Before you left, you made a promise with them, one they never forgot, even when you did.

When you were nine years old, you moved to America. Shortly after, you were hit by a car. You survived, but the accident took something from you that could not be replaced: your memories.

The past became a blank space you could not reach, no matter how hard you tried.

Years later, you meet Yui, a girl who becomes your closest friend and the one person you can rely on. But your life changes again when both of you are sent to live in the same mansion as the Sakamaki brothers.

People you should have known. People who remember you. People tied to a promise you cannot recall.

As fragments of your forgotten past begin to surface, strange events start happening around you. Powers you cannot fully understand awaken inside you, and every year, something inside you changes.

Sometimes gentle. Sometimes unstable. Sometimes deadly.

The more time you spend in the mansion, the more dangerous the truth becomes.

Because the promise you made with the Sakamaki brothers was not just a childhood vow.

And whatever you once agreed to, it still hasn't been fulfilled.
