Okay, so ignoring my latest status, I just read the DMC5 prequel novel, and I finally figured out DMC2 and DMC5's place in the timeline.
So sum up what I know about Dante and Nero's ages watch the following video, as this guy has reached the same conclusions as me regarding DMC1, DMC3, and DMC4
Okay so the novel shows how Nico and Nero met for the first time, and says the events of DMC4 happened 5 years ago. Meanwhile, Dante is meeting with Martier and Lucia, and mentions the events of DMC2 were about 10 years ago. The last chapter, which ends with the scene of Nero losing his arm, says Nico had now been living with Nero and Kyrie for a year. Meaning DMC5 takes play 6 years after DMC4.
So if Dante is 38 in DMC4, and Nero is 19. Then that would make Dante 43 and Nero 24 in the novel, and 44 and 25 in DMC5, and if Dante is 43 in the novel, then he was around 33 in DMC2.
So it goes DMC3-9 years-DMC1-5 years-DMC2-5 years-DMC4-6 Years-DMC5
