Something awakes you.

Being honed in the art of shinobi, you're sensitive to possible threats to your life. That very danger sense is what causes you to wake up at nearly midnight, weapon already palmed in the right hand.

Nothing.

You extend your senses to cover the whole house. Only two people are inside the house: Tsunami and you. You might have missed any intruder if he or she is stealty enough but that possibility in not very likely.

It was then you hear a small muffled sound coming from what you believe is Tsunami's room.
