The Demon Kings are are the inverse counterpart of Angels in the mobile game Date A Live by Amino. They are also known sometimes as fallen angels, due to the fact that when a Spirit enters in Inverse Form, the true form of the Spirit is revealed they are more cruel and dark angels version. They are similar to the formats of weapons of angels, however, the texture and color of the weapons seen more and more powerful demonic.
They are also the counterpart of the Tree of Life as also as the Spirits in the Inverse Form, the tree that belongs to them is the Qliphoth Tree; The Qliphoth / Qlippoth / Qelippot or Kelipot are the representation of evil or impure spiritual forces in Jewish mysticism. The realm of evil is also termed 'Sitra Achra/Ahra' in Kabbalah text.
