This game has nothing to do with the first four generations of the Devil May Cry (except the names of the characters ...), and the location of the story is different from the first four generations, which is in the parallel world of the first four generations (that is, another interface ... Jet Li's "Savior" should have been seen, which probably means this).
In the new Ghost Cry, Dante is a half-blood between the devil and the angel (the first four films are all half-blood between man and the devil, so it should be no stranger).
Plot: The demon Sparta broke the demon's commandments, fell in love with an angel, gave birth to twin sons V (Virgil) and D (Dante), and lived in seclusion.
The good times didn't last long. Mandas, the demon king (ps: Mandas is the brother of Sparta, and he only knows the existence of D), and then he came after them.
Finally, D's mother was brutally killed by Mandas. In order to protect the children, Sparta erased D's memory and left with V. Later, Sparta was captured and exiled. (It seems to be exile ... I forgot. V didn't say anything. When I grew up, I set up an organization called "Cult" with the aim of eliminating the evil organizations in Mandas (music, news and even drinks in Mandas).
V found D, took him into a cult, and helped D recover his memory. The two brothers cooperated and finally defeated Mandas.
After that, V actually wanted to rule mankind, not Mandas.
D fight for mankind v ~ (the new movie Dante is over, and a DLC is the story after Dante)
In DLC, V and D left miserably after the decisive battle, died before reaching a grave (it seems to be his mother's ……), fell into hell, and returned to the human world from hell to gain new power and become a fallen Virgil. Finally, the demons all followed Virgil.
Typing by hand … I hope it helps you.
