I'll post what I THINK I know so far.
Demons entered Eva's house (apparently Sparda was dead and Dante and Vergil were still kids). Dante hid in a closet crying, his mom was outside of the closet trying to stop the demons from learning where he is. Vergil on the other-hand trys to fight the demons with Yamato. He can't protect his Mom, and she ends up dying. Vergil runs away and Dante is still hiding. Vergil eventually runs into more demons and.......
SPLAT, they knock Vergil's Sword into his chest and he was impaled. He starts slowly dying, but then O_O His devil trigger first appears and he defeats all of the demons
^I'm not 100% sure if thats what I read from the manga or from a fan-fic sorry. I haven't read it in a long time and don't currently have it with me.
I'm gonna have to say that is from a fan-fic, you said you haven't read the manga, only read about it. That is way too specific to be from general or the current official sources.
Facts are: (Correct me if I'm wrong, otherwise I'd be lying)
-Sparda "awoke to justice" and rebelled against his own demon kind "nearly 2000 years ago"
-Some unknown amount of time before or after that, Sparda sealed away Temen-Ni-Gru, "a gateway to the demonic realm." In the process he used the blood of "a mortal priestess," also a member of Lady's bloodline.
-Some unknown amount of time after those first two events, Sparda stayed in the human world and wedded a human woman named Eva. Together they raised two sons, Vergil and Dante.
-An unknown amount of time after that, Sparda eventually died, this is all up to speculation as to how. (What appears to be a popular theory is that he became Human after sealing away his demon powers and presumably died of old age. Once again, we only know he died, not exactly how so)
-An unknown amount of time after Sparda's death, Eva was murdered by demons. (Where these demons came from or why they murdered Eva is not known as of right now)
-An unknown amount of time after Eva's death, Dante and Vergil live out their lives seperately.
-Roughly two years (as vaguely spoken by Dante in DMC3) since they last met, the events of Devil May Cry 3 begin.
-The events of Devil May Cry 3 end. Vergil chose to stay in the demonic realm, left with only his side of Eva's amulet, and the Yamato Katana. We are seen as he, in a presumably weakened state, runs towards three brightly glowing orbs in the sky. We know this to be Mundus. Dante escapes the Demonic Realm and Temen-Ni-Gru with his side of Eva's amulet and the Force Edge. Dante and Lady put "Devil May Cry" into full service. They begin taking jobs together. What happens to Lady between this time and Devil May Cry 1 and 2 is unknown.
-An unknown amount of time after the end of Devil May Cry 3, the events of Devil May Cry 1 begin.
-An unknown, but presumably short, amount of time afterwards, the events of Devil May Cry 1 end. Dante has realized Vergil was, in fact, the armored demon chasing him throughout his journey. Mundus, though not known if fully destroyed, is sealed back into the Demonic Realm. Trish and Dante contine the devil hunting services of the renamed "Devil Never Cry" Trish is given the Force Edge.
-The events of Devil May Cry 2 begin. (Seeing as how I never got to play this, I am not sure if anything important transpired before or after DMC2)
Of course, all of the unknown speculations about Dante, Vergil, Sparda, Eva, or even Arkham and Lady before the events of Devil May Cry 3 could be resolved in the Manga. I wonder if it will receive an English localization.
