Ibuki's Rocks To Her Death.

You are woken by the sound of loud metal music.

After discovering that the music is coming form behind a locked door, you break it down to discover Ibuki Mioda, with a knife sitting in her neck.

The stereo is sitting on top of a shelf, near where ibuki's head is lying. Next to her on either side are two candlesticks. broken pieces of a pot are scattered around the room.

You find a remote for the stereo outside on the altar.

Someone corrected Peko's arms so it looks like she's shoving the sword into herself.

How could a murder occur inside a locked room????

A small piece of black fabric is within ibuki's hands, and it's clear she's been drugged with a sleeping pill.
