Lucius isn't using full power of Lucifero or Julius powers in his base form. That's something neither stated nor implied, so I have absolutely no idea where you're getting that from.
Let’s take a look shall we? It is a burden on you to prove that he was holding back.
1.) base form Lucius no diffed 50% Lucifero. And from what we can see,it took 1 spell and he has no injuries. Saying otherwise is headcanon unless you can provide evidence otherwise. so base Lucius > 50% Lucifero at MINIMUM.
2.)This also makes sense when we know that Lucius has luciferos first heart.and after he beats Lucifero we can see him eat Lucifero second heart.
3.) We know that the heart gives him Luciferos power. So obviously if Lucius already ate the first heart he would have 50% of Lucifero power,his own + Julius power. So obviously 50% Lucifero would stand no chance and that is why he got no diffed
In fact all the evidence suggests otherwise, such as Asta himself saying he isn't stronger than Julius yet, and yet he's still able to go toe to toe with base Lucius, and him comparing base Lucius to base Lucifero
[1], which showcases the fact that base Lucius isn't as strong as you think he is.
4.)it is directly stated by the captains that Lucius is more powerful.and using context of them basing it off him soloing the underworld,we know it was referring to base Lucius,as Lucius soloed the underworld in base.as we can see with Lucifero.
5.) now for Julius.Lucius (base) tells asta that he is stronger than Julius. Asta responds saying that he would surpass the wizard king in this fight..and then they fight.so it is very obvious that if Lucius is already stronger,and Asta is comparable then…
Lucius time magic is quite literally bigger than Julius. so idk what headcanon you are using to say he is holding back.
6.) Asta doesn’t compare Lucius to Lucifero. He sees Lucius using Lucifero power. When he sees them. He says that he has gotten stronger (he has trained) since the timeskip .which is clearly showing that Luciferos strength is not a problem .
asta is confident in winning even after all those factors.proves that he is at least comparable (lowball) to what he can sense and has seen.
Also asta is stated to be a threat.
Which in context, refers to Lilith and Namaah, a supreme devils, due to the power Damnatio is receiving from a supreme devil name Baal, who is infinitely inferior to Lucifero.
it yet again makes no sense. We can look at people like Noelle who fought megicula. This Noelle is VERY clearly MASSIVELY weaker than current Noelle. Yet current is still struggling with a paladin. That is nerfed,while she is buffed by neverland.makes no sense to say that paladins are just stronger than the weakest floor devils.and idk what the amp was accepted as on here, but a paladin is always stronger than the supreme devil they host. As it is literally them using supreme devil power + a massive amp.
That's cool and all, but he’s not referring to Lucifero.
I genuinely thought for a moment that you would provide a meaningful argument, and not just a bunch of headcanon and misinterpretations passed off as evidence and narrative.
from the land of the rising sun,we find out that paladins are the strongest people the ryuzen 7 have fought. This logically includes asta. Same asta who was fighting Lucius. Even more so all but 1 ryuzen 7 member smoked asta even without using magic. (Tho this was base asta they were both holding back) Asta says that even if he used all his powers he still wouldn’t be have lost to ichika (who didn’t use her magic suit yet) which shows that she is more powerful than the Lucius he was confident in beating.
The idea alone that they went from being absolutely unable to do anything against base Lucifero in the Spade Arc to being able to one shot 50% Lucifero in the current arc is extremely absurd in itself and something that even the narrative itself would slap the soul out of you, if it heard you.
the idea that they can’t close a few times gap within a year and 3 months timeskip even though we have seen them do that even mid fight is what is really absurd.
Julius wouldn't even be relevant to them anymore if that's truly how strong they've become now, unless you scale Julius above 50% Lucifero
can simply argue that Lucius was affecting Julius fights and that is why Julius seems weak..which is far more supported than you would think.there isn’t even a reason for Lucius to bring up the fact that he is now stronger than Julius (when Julius hasn’t been relevant for hundreds of chapters) that would just be an obvious statement.
type 4 acasualty incoming
. (If I am being honest I don’t think it will be outright rejected. Likely just going to say it needs more evidence or sum.
Edit: idk why the scans keep going in the wrong order
