"I know you're in here!" Miku hollers into the echoey darkness enclosed within these four walls.

She can't see anything but she has herself pushed up against a counter in the kitchen connected to the living room. She focuses on her breathing- in, out, in, out- in deep breaths as she tries to recollect herself before these last few moments of blood on her hands. Without taking her eyes off of the abyss of the living room, she moves her hand back and feels around for anything atop the counter. Suddenly, her hand touches something long- a handle- and her fingers wrap around it to pull out a silver knife.

They took her childhood best friend, Rin, along with her acquaintances she could barely seem to consider "friends," Ia and Meiko. And her best friend Kaito? God knows what's happened to him after he disappeared all too suddenly when Miku left him for five seconds. She could only assume they took him because there was no one else to blame who seemed worthy of accusing.

Nor does she know where Len vanished off to.

Miku does her best to examine the knife in the dark. She lays the blade in one palm and holds the handle with her other. The steel is sharp and pointed, and if little light could flood in from the moonlight through an uncovered window, the blade would be glinting ever so brightly to make her blind. She twirls it around so she holds the knife with its blade pointed outward to her enemy. She raises it in the air and carefully moves inch by inch from her spot in the kitchen, making way into the living room.

"Who are you!?" she shouts. "I know you're in here, so there's no point in stalling for time. And if you're just trying to make a stealthy attack on me," Miku straightens her body and slowly spins around, "it's not going to work."

Thump!

Something hits the ground and something else starts rolling across the wooden floor. A distraction, Miku imagines. Considering it's happened many times before in the past, she can tell they knocked over the battery-filled remote control to the ground, unintentionally or not.

She won't let this throw her off guard.

"Why are you doing this?" If they won't show themselves, she might as well ask questions in the dark in the hopes they'll answer one. "Why are you killing everyone? People I know... the most important people in my life... What are your intentions? ... Do I... Do I know you!?"

Finally, she can hear their breathing. Slow and steady unlike hers that's beating a thousand times a second.

She closes her eyes, inhales one deep breath, then opens them to shout:

"Are you too scared to reveal yourself to me!?

She turns her head around to the killer she thought was behind her, armed and ready with her knife. But instead, she feels an arm wrap around her neck with its own knife pointed below her chin. As Miku raises her weapon to stab them, the killer's other hand firmly grips onto her wrist.

"The one who should be scared of me," they lean in close to her ear, "is you."

Miku's knife clatters on the floor.

"Len?"

Side notes: Some of Miku's friends are gone because of a killer and who she expected was taken by them was her friend Len. But to her surprise, she soon finds out he himself is the killer.

A/N: After finishing the sketch of a drawing, I was inspired to write this. Len betraying anyone just amuses me so much. Gahh, I love it〜 If anyone's saying this is similar to my very old fic "Slain," just- shhhh... I didn't realize this drabble was similar until halfway into writing it. Just... imagine this is like an improved, cooler version of "Slain" with a switch in the killer XD
