merem solomon's demon of the left leg
The Daemon of the Left Leg (左足の悪魔, Hidariashi no Akuma?), classified as the King of the Sky (空の王者, Sora no Ōja?), is a manta ray-like daemon around two hundred meters in size. The concept behind its creation is that of freedom and shooting for the cosmos. It is considered to be his most beautiful creation with membranes composed of countless animal species. It "swims" through the skies and remains unmatched in the air, but will face destruction once it touches the ground. It is meant to be used in situations where one-on-one combat against a strong opponent is necessary, though it has a weak defense that will cause it to fade away after receiving severe damage. Merem believes that it is a great weapon with too high a cost to properly utilize.
