Unleash the Mystical Black-Gold Creature

The image shows a fictional creature from the anime world. It has a broad, massive, black body with golden details. It has two large hands that are almost as wide as its body and there are chains connecting the hand to the shoulder and the shoulder. It looks like a rectangular shield made of black tree trunk and in the middle of its body from behind there is a complex circle that looks like a gate or magic seal. It is made of black wood. The creature is covered with cracks and glowing golden lines, and it has no legs but floats like a ghost on four things that look like tree trunks.
