Jesus Christ I go away for a few hours and this happens?
Anyways I’m still staying neutral but I am going to say this, the light is 100% referring to the human world when they verbatim refer to it as the human world. It being hope or whatever is complete headcanon and relies on ignoring the next line. Honestly the only way this can argue against Tier 1 DMC is if you’re taking the PoC statement about the light that split the world apart.
And I will bring up this since I have a feeling that someone is going to being this up in the future so we might as well address it. Souls in DMC, more specifically Demon souls are
shown to be the devil arms that Dante and Vergil uses in the games they’re in, so if there’s any explanation that can debunk this being an anti feat for tier 1 souls they should be brought up to clear up any misconceptions.
To be frank, the manipulation of Souls in DMC can't be used as an Anti-Feat. Dante and Vergil explicitly have a Demonic Power that
converts these souls into physical objects, which honestly makes sense because they can rewrite Names, which are large portions/fragments of the Soul that also predate reality. (As in, ALSO around the era of the Original Chaos.) They also have Soul Manipulation to begin with.
This ability doesn't exist for someone like Nero, (at least for NOW), who can only absorb Demonic Power through the Devil Bringer. (Though he can manipulate Souls.)
The only people who don't have this power who manipulate these Souls (that aren't Nero or other Demons), is Humans, which we know can harness Demonic Power for their own needs via rituals, (Arkham), intense study of magic, (Arius), and those who have turned themselves into Demons, (Agnus/OotS and Chen), after their research of said demonic arts via science. Nico only manufactures artifical Devil Arms, and she makes clear that she could only do that with her father, Agnus, research.
Further, any normal Humans who wield Devil Arms have to be "
strong enough," to use them, otherwise these Souls/Devil Arms consume them. While this isn't indicative of Tier 1, it IS of the fact these weapons are not able to be wielded by anyone. They are objects of immense power that can improve even the power of other Demons (as Lucia specifically stagnated in power and only had Devil Arms left as an avenue to further increase her powers). And as we know from Kaitai Shinsho, a
strong Human Spirit can amplify Demonic Power, providing power in general, as well as allow Humans to survive what would ordinarily kill them. There also isn't anyone who does so in canon anyway, outside of Lady, who is the Descendent of a Priestess and Arkham, who intensely studied magic and even told his daughter stories about said magic, (something Lady tells us herself in the DMC3 Intro). Info she likely put to good use by
using Silver to hunt Demons. She's also clearly not the normal person, having survived and endured the events of the Temen-ni-gru.
In short, the series doesn't have any real Anti-Feats surrounding Devil Arms because the people who do have to be a Human who has harnessed magic, has accessed their Human Spirit, or are part Demon in some way. All of which is connected to the power system that created the souls to begin with: Demon Stuffs.
Edit: Also, forgot to mention, but we don’t scale individuals to 9-D by just messing with Souls. They get 1-C from messing with the Dimension that created Souls/affecting the entire cosmology. That’s why only God Tiers get 1-C to begin with. So no low tier Demons or random examples (such as Devil Arms) would apply regardless.
