Demons can undergo evolution and raise their ★rarity by sacrificing other demons with the same ★rarity or by using Yata Mirrors.
The rarity of all demons can be raised, with the highest possible rarity being ★6.
※The demon to be evolved must first be at max level.
※After reincarnation, the rarity of the demon and its max level will increase, but the level of the demon will return to Lv 1.
※Demons used for reincarnation will disappear.
