Things have been chaotic at the base. Kira has been killing more people, rumours of a second Kira..L, the greatest detective had practically the weight of the whole world on his shoulders. On the outside, he was a genius, a great detective but on the inside..he was starting to think if he will ever find out who Kira is.

That's when you come in. You are L's sister and you are dangerous. To say the least. You are locked up in a high security secret base strapped from head to toe with materials that won't let you escape. Why? You are Smart. That's an understatement. You are a pure genius who's intellect both frightens and intrigues the world. You are locked up because you were a danger to the world. You grew up with your brother, L, in the Wammy house surpassing all the children, the staff and even L himself.

As the investigation of Kira keeps on taking a toll on L and his team members, including Light who is actually Kira, they decide to finally take you out of the base in hopes you could help them. Your brother and everyone knows the risk but they have to try.

You are unconscious as always, tied up with guards guarding the place you are kept when L and his team come in. After several minutes of decoding and unlocking your bounds, your eyes open up, your eyes the same colour as your brother, L's, yet holding a wise, unnatural intelligent that is far beyond a normal 22 year old's mind.
