Wrong in all possibilities.
First i'll answer about seiya chapter 1, because that's simply ignoring not only what the manga of saint seiya speak, but also as to the novel itself you passes is being ignored, and it's not being realease the whole context.
The answer to seiya ch. 1 to have 7th sense
in this novel is absolute: Yes, he had.
In Ch. 2 of the novel, here of
saintseiyapedia itself, it is said;
Chapter 3.5
The cosmos
It is something that it is impossible to understand completely just with words. It is the Seventh Sense.
All humans have in them five senses which are Touch, Sight, Hearing, Taste and Smell in addition to another which one could call the sixth sense. People who are commonly called "psionics" are awakened to this sixth perception which gives them various gifts, some examples of which are precognition or a supernatural intuition. But there is still an additional meaning beyond this. This is called the Seventh Sense.
In mythological times, the era of the great heroes, the separation between humans and the Gods was not as distinct as it is today, and everyone possessed the Seventh Sense, but this fantastic power was lost as and as the human race evolves. Yet even today human beings still carry the Seventh Sense deep within them, at the very source of their existence. It is through the use of this meaning that the Saints are able to exercise superhuman powers, by burning and exploding the energy which is the basis of everything. However, the Seventh Sense, the perception that surpasses the other six, is something that even the greatest sages of Humanity could not explain exactly with words despite extensive research, it is what makes it possible to give birth to a power immeasurable ... He is the Cosmos.
The 7th sense is nothing more than the cosmos itself, and according to this novel, in the ancient time of the gods ALL HUMANS had the 7th sense awakened, and even in nowadays
ALL HUMANS have it within their soul, and by that meaning the
saints are able to exercise superhuman powers, by burning and exploding the energy which is the basis of everything.
So, yes, it's the same as not only saying that seiya chapter 1 is 3-A, but also the same as saying that every human in the verse has an real sized universe in their souls.
But that's not real, because as i've already shown by WoG, Cosmo is just a micro sized universe, not a real sized universe. And i wouldn't even need to show it, because in any translation of saint seiya in chapter 1 speaks that the body of the human is a microcosm/microuniverse born of the big bang.
- note: if it comes with the argument "But in chapter 1 is used microcosm with Õ░ÅÕ«çÕ«Ö and not Õ«çÕ«Ö" i've already explained why the author no longer uses "Õ░ÅÕ«çÕ«Ö" completely and uses just "Õ«çÕ«Ö", and is why he just doesn't want that, and you must have to read in the way of his WoG.
Then again, the phrases;
- "Burn my Cosmos!" Shouted Seiya, ready to attack.
- A Big Bang happened. This was the power capable of creating miracles. A person pushing his Cosmos to its climax could awaken to the Seventh Sense and reach a power comparable to the energy which had given birth to the Universe.
It doesn't mean a 3-A energy, just means that seiya was burning his 7th sense, his cosmos, and his universe (micro-sized) get a big explosion, a.k.a big bang.
This is not supported by any feat, because all other feates presented are just wank and forget the main base of the work, like;
Then there is supporting evidence such as Hyoga breaking free from the Ice Coffi
The ice coffin was destroyed by a star level weapon
Weapons coupled to the Libra Cloth, capable of shattering the stars
Shiryu surviving the backlash of a massively far above baseline Tier 3-A/Low 2-C attack
It's an outlier.
Ikki surpassing Shakas Cosmo.
Wrong too, ikki have surpassed base Shaka is just a 4-A feat, baseline shaka is just Multi-Solar System Level, according to our profile.
https://vsbattles.fandom.com/wiki/Virgo_Shaka
And looking profoundly to the profile of both, ikki skipped a tier of energy variation from MSS to Galaxy just by defeating an MSS, it doesn't make sense.
