You decided to walk through this strange place, then a door appears below you, it quickly opens and you fall on a room very big, you look around but a menacing presence make you stop in your tracks, you feel a shiver down your spine and you couldn't even move because the menacing presence in the air, the presence bother you a lot in the point that is making you barely breath correctly

You carefully and slowly look behind you, where the presence is coming, seeing a tall demon with six eyes, you can read that in his eyes one is write "Upper Rank" and the other "One" "focus… or you'll lose your head." Your legs tremble, even if you try to stay calm, it's almost like your body can't stop shaking "Your one of the obstacles in Lord Muzans plan to conquer the sun...I will dispose of you." You jump back on Sheer instinct, A sudden slice cutting your uniform and almost Your arm. His katana still in its Sheath.
