Darkest Theory: Isagi (+ Hiori, Karasu, Otoya) Will Definitely Find Out About Yukimiya's Actual Eye Condition (Optic neuropathy) before Yukimiya gets eliminated in future Blue Lock manga chapter
As Yukimiya stan, I hate this idea but I still had to accept that Yukimiya is getting eliminated in future manga chapter (after U20 world cup arc) because it is part Blue Lock plot of having one striker left which is definitely Isagi.
For Chigiri's right torn ACL, Isagi, Nagi and rest of them know about it. However, for Yukki's eye conditions only Ego knows. (Don't believe what AI tells y'all in Google on Isagi alr knowing Yukki's secret.)
According to chapter 205, Yukki mentioned on his teammates gonna get worry if he reveals the truth of his eyes conditions. It means Isagi and others doesn’t fully know about Yukki's eyes having dark spot after he plays on the field for so long.
In chap 171, Isagi says "you're blind to reality " to Yukki but Isagi thought it's a normal eye condition. But Yukki's eye conditions is even worse.
I feel like Yukki's closest people like KYOH (minus Y for Yukki) might find out about it as well.
Karasu: I think Yukki told Karasu about his eyes off-screen in S1 or S2. If not, he will find out in future manga chapter.
Otoya: Otoya doesn't know about Yukki's eyes. Tbh, there is less screentime for Otoya and Yukimiya compared to Tabiken, Tabieita, Tabiori and Yukiori.
Hiori: I'm surprised that Hiori still doesn't know about Yukki's eyes even though this two were roomates for the longest time. I know few people said Hiori knows Yukki's eyes in 2nd NEL match like in halfway Yukki had to take off his goggles and rubs his eyes. In reality, Hiori doesn't know Yukki took off his goggles in halfway coz he was turning behind. Hiori thought Yukki was crashing out on Isagi. If Hiori saw that, he would have asked more on Yukki's eyes condition to him in training before 3rd match.
So...Isagi, Hiori, Karasu and Otoya gonna find out about Yukki's darkest secret in either U20 World Cup or the arc after U20 World Cup.
If Yukki successfully hides his secret from this four people and gets eliminated, that's a miracle!
Tbh, I prefer him revealing his secret to his friends and let them help him to him hiding his secret and suffering in silence. Pls, don't be like Miraculous Ladybug where Ladybug and Chat noir will never reveal the secrets to each other.
