The Ixseed (十六種族, Ikushīdo) refers to the 16 sentient races of Disboard whom the Ten Covenants apply to. They are ranked based on their affinity to magic.
The top 6 races are regarded as "Life" (生命, Seimei) and "Living beings" while the bottom 10 races are regarded as "Creatures" (生物, Seibutsu) and "Living things". The split between the top 6 and bottom 10 races represent the difference between the heaven and earth, as the "Life" are vastly more powerful than the "Creatures". All races were created by the Old Deus, except Immanity and Demonia.
