Room 231

Just as your hand is about to touch the door knob of the Room 213, you feel that something is not right with the whole situation. Are you walking into an enemy trap? No, that couldn't be, as your instinct as trap master doesn't trigger. Besides, you couldn't any people with high chakra, power that allows anyone to launch jutsus, in the vicinity.

Regardless, the wrongness about the situation still will not go away.
