This is the era of magic recovery: 1. Some people and animals will suddenly become magic fetuses and parasitize others; the reason for changing magic fetuses is still unknown. 2. The magic fetus will only parasitize people who are seriously ill or seriously injured.Healthy and able-bodied people are not parasitized. 3. During the parasitic period, the magic fetus feeds on the blood of the host; when the host dies, the magic fetus will also die. 4. Under the strong stimulation of chance and coincidence, the magic fetus may undergo awakening and transform into a demon that feeds on human beings. 5. After awakening, the first thing the devil does is to devour the host that has been supplying its blood.Background: Japan's Edo period cp: Pure fishing system human host shou x kind and honest parasitic magic attack Kusama Ash
