A kid watching gameplay cuz ma duke not buying the game is a different conversation from a grown ass man thinking he got a opinion on a game he watched 12 YouTube walkthrough videos on
DMC4 will not tell you why did Nero had a Devil Bringer in the first place just hint
DMC5 will subtle hint about Kyrie's back injury
Both games will never tell you that in order to know this. They expect you to read the Deadly Fortune light novel in order to understand it
