So I just started this game and I'll update as I go but Blu's sword in the first chapter has some resemblance to red queen from DMC4 and I love it
First update: I'm in like 8 or 9 chapters in and I was right, it was totally inspired by Nero's Red Queen, from the name, to its attacks(Helm breaker and stinger are especially popular from Dante but Streak actually does come from Nero himself). So crack theory: Eric will get a weapon, or a type of magic, that symbolizes him as a human, like Blue rose was for Nero(He's the only one who can wield Red queen because of his demonic heritage, but anyone could wield blue rose if they know how bad its recoil was)
