Well another demon for the group this time it's Shadow unoriginal name aside this is where Night canonical would get his proper demon form from at least the one he uses. Even if his nightmare form which he has much longer resembles him this is a proper demon. Obviously unlike Re and Cha he hides his runes and would be much older and likely much stronger. This demon is strongly connected to Night though not friends if the two would meet they would share respect for the other and not under no circumstances fight. At his minimum size he is 2 feet.
