Of course, it will take time for Alex to adapt with his new eye even though it fits perfectly with his left eye socket. After all, his vision is a little different with 2 Rinne-Sharingan.
Fortunately, he gets used to it quickly and it really enhances his Rinne-Sharingan's abilities. His 6 Rinnegan skills are stronger now, strong enough to make him match the Tailed Beasts with only Rinne-Sharingan's power.
But it might still not be enough to defeat Acnologia even when he transforms into the Tailed Beasts and also uses his Rinne-Sharingan.
Acnologia is just too strong in reality. If his soul wasn't separated from his body after he tried to consume space and time, the Dragon Slayers won't be able to defeat him.
But Alex can't rely on that because things have changed. His presence alone has caused changes in this world, not to mention he actively changed a lot of events.
There is no guarantee that Acnologia will try to consume space and time again or if he will get into a vulnerable state after that.
It's too uncertain, so Alex can't rely on that to defeat Acnologia. He needs to make sure he truly has the necessary power to defeat Acnologia with his strength.
Besides, he still needs a lot of power to face the incoming war. Alvarez is also a great threat to Ishgar. So he needs to get stronger no matter what because he will also be one of the enemy's main targets.
However, as he has thought, he can't use Susanoo even with 2 Rinne-Sharingan. It's probably as he has expected, because his new eye is from his future self, so both eyes are basically the same eye.
He has been expecting this because Susanoo needs a real pair of eyes, not an eye cloned into 2 like this.
Well, even without Susanoo, having his Rinnegan's skills stronger is already worth the effort and his future self's sacrifice.
Also, with 1 Rinne-Sharingan, Alex can float and fly like Pain. But with 2, he can even fly when transforming into a full-sized Tailed Beasts and in his human or humanoid forms, he can fly very fast.
Now that he can fly when transforming into giant Tailed Beasts, he can fight Acnologia on a more equal ground.
The only Tailed Beast that can fly by nature is Chomei. That limits his options in aerial battles too much.
Now he is free to transform into any Tailed Beasts and will still be able to fight everywhere, be it on land or in the sky.
While still trying to adapt with his new eye, Alex is going to the Sun Village. He has asked Flare to guide him to the Sun Village because he wants to meet the Giants.
Alex only asked Flare, but somehow Ultear also joins in, saying she can't leave Flare alone with Alex as if he is a terrible pervert when he is the most normal member of Fairy Tail.
Though it seems Ultear's real reason is Meteor because as soon as they meet, she runs to hug the fluffy bear. Flare also joins her, leaving Alex alone on the side.
"So why do you want to meet the Giants?" Ultear asks while riding on Meteor with Flare, leaving Alex to walk alone as they go to the Sun Village.
"I actually need to talk with their Eternal Flame about something very important. But I need to ask the Giants first before that."
Flare is surprised that Alex knows and wants to talk with Eternal Flame. It even makes her rather nervous. "W-why do you want to talk with the Eternal Flame?"
"I need to ask him about Acnologia. As a Dragon, he might have information about Acnologia that we humans don't know."
"Eternal Flame is a Dragon?!" Ultear is the one surprised now. She has heard about Sun Village's Eternal Flame from Flare, but only that he is their Guardian Deity, nothing else.
"Yeah, but I believe he is like a remaining part of his real self that still has consciousness. If he is still in his real full form, Acnologia won't leave him alone. I believe the one who caused him to be in his current state was Acnologia. But whether he has fought Acnologia or not, I believe he has more information about Acnologia than us humans. So I need to ask him."
That's not Alex's real reason, of course. He just wants to see if Gray's father, Silver who is controlled by Tartaros has frozen the Sun Village.
Alex hopes that Silver hasn't come and he can meet Silver later. He wants to find Tartaros's HQ through Silver and maybe lets Gray meet his revived father to have a real talk instead of just fighting through pretense.
Well, he is revived and controlled by someone, so it will be difficult to do despite the freedom his "Master" gave him. Alex might even need to kill him if he doesn't cooperate.
He will feel bad for Gray, but right now he needs to find Tartaros and destroy them quickly before they attack the Council which will cause chaos in Ishgar.
While Alex doesn't like the Magic Council, he knows they are an important organization in Ishgar's Magic World.
They also have many Mages and weapons that will be useful for the war against Alvarez, so he needs to save as much as he can.
He doesn't want to see Tartaros attack cities which will surely cause casualties among civilians. Also, he has been chasing them for years, so he wants to destroy them himself.
But the main reason is the Book of END that is om Mard Geer's hands now. In the series, Zeref took it after Tartaros's defeat. Alex doesn't want to let Zeref take it, so he will tale it himself.
He needs to change the content that can affect Natsu's life and death matter before killing Zeref. Alex can't kill Zeref before making sure Natsu won't die when Zeref dies, so he needs the Book of END.
Anyway, after traveling for quite a long way, Alex finally reaches the Sun Village with Meteor, Ultear, and Flare.
Fortunately, it hasn't been frozen yet. Though he doesn't know if Silver wasn't meant to arrive yet at this time or if it's different from the series because the changes he made have affected a lot of things.
Tartaros must've affected greatly by his presence because he has destroyed many of their subordinate Dark Guilds and also killed Etherious Demons affiliated with them.
He has destroyed so many of their stuff and killed so many of their members that he is confused why they haven't come to kill him themselves.
But well, he was frozen solid without being able to do anything for 6 years. They thought he was dead and there's no need to kill the dead.
He has just started being active last year, so they haven't even prepared to attack him who obviously has gotten stronger.
They were actually trying to gauge his strength by watching the Grand Magic Games' broadcast. As arrogant as they are, Tartaros know which lowly humans they should be careful about and not.
For Tartaros who know about Acnologia's power, Alex who can survive a battle with Acnologia and even get stronger as a result is more dangerous than even the 10 Wizard Saints.
So they shouldn't underestimate Alex and think of him as someone who can kill them. Even so, they are still looking down on him after watching his battles at the Grand Magic Games.
They said they have been overestimating him because of his feat against Acnologia and because he has destroyed a lot of their subordinate Guilds.
Although Alex could defeat the other participants alone, all members of Tartaros still think he isn't that strong and they can defeat him.
It's because they have so much pride in their origin as demons created by Zeref and their Curse that they believe to be far more superior than Magic.
Well, while they still look down on Alex, they also still acknowledge him as a threat to them. They just don't believe he has the power to defeat all of them even though he might be able to defeat some of them.
Anyway, Alex's real goal is to meet Silver and find Tartaros HQ's location. Rather than waiting for them to attack first and letting them kill people, he prefers attacking them first and killing all of them before people die.
But first, he needs to talk with Atlas Flame. His real goal might be different now, but it's still true that he wants to ask Atlas about Acnologia. Tartaros is just a Side-Quest. The Main Quest is still the undefeated Acnologia.
