What is "Tesengai"? I assume you mean "Tenseigan" since this is the closest thing to what you said.

Does the potion only work on squibs or can it grant magic to a muggle?

Gray wasn't the one who traumatized him, it was Natsu himself who traumatized his past self.

Why is her name Amélie and not Fleur?And she is Delacour, not Delacroix.

So the protagonist tries to expose a fraud and he was so stupid that he did not make any backup to make sure that justice is done if something happens to him.

Why does the MC have Haki but he's so pathetic? He could have previously killed the Logia user with his Haki but he didn't.

I only read the first chapter, but even so I prefer to go read the story created by Einlion, no matter how "Simp" the MC is supposed to be or what you say since you said that you didn't read it much but at least he won't make me pay for a crap full of "please go to my patreon and give me money" ads just to have a fic full of Smut.

Después de leer más de veinte capítulos, solo puedo decir que el protagonista es insuficiente y estúpido. I really dislike this fool. I could start saying everything I don't like but it would be too long and I'll pass.

Or Sprigatito since he likes cats.

I prefer if he is paired with Lily because it will hurt Harry and James a lot more.

Hopefully Severus will discourage Draco from dating with Lily in a slightly violent way if he doesn't understand in a good manner. I don't like the couple at all and I'd rather she date even the idiot Potter than this aberration.

I hope Draco isn't Lily's boyfriend and Hermione doesn't give Sirius a chance and for the rest I just want to see Severus doing whatever he wants at Hogwarts.

I'm waiting for Robin's Flashback. The happy part with Saul and his "dereshishishi" and Robin's "dereshishishi" running away from the ruins of Ohara. I'm also looking forward to the rescue of Going Merry and for her funeral you could have the stores play a video of the funeral and her memoir with Merry or at least the song "Dear Friends".

I don't agree with those who don't want Lily in the harem. I think he must have it just from reading James and Harry's reaction. XD And he should also have Hermione in the harem for her being so smart and talented.

This guy someone who asks for a lot of money for promises that he won't keep about his garbage stories whose only promise is some smut (which is not very good) and the story is pretty mediocre from what can be seen in the few released chapters and If one notices, he only has good grades in his stories thanks to his multi-accounts where he does the same in each of them.

The author must not like Obito because he could kill practically all Akatsuki himself.

Slughorn?

While I don't agree that Otohime is ugly, I don't consider her beautiful either, she's just there as "pretty", but anyway I prefer that you don't ruin the beautiful family that Neptune and Otohime form in the canon just to fill more a they will do what is already there (it gets to a point where it starts to get boring and I prefer it to focus on more reactions and less romance out of the blue). I want to see Shirahoshi born and not as the daughter of the protagonist.

Well, for me Snape (both in the book and in the movie) I liked him, his description of the book is like that because Harry likes to satirize the appearance of others and exaggerate, on the other hand, the marauders except Remus I like so bad that I will not say completely what I think because they censor the comment. The reason for Lily's anger was because Severus would join the Death Eaters, I don't think the word itself since it would be a hypocrite (she used Snivellus) for an insult given out of anger at humiliation and it could be said that it was also almost sexual harassment for pulling down his pants in front of everyone. I don't know how that is considered a joke, like sending someone with a transformed werewolf and knowing what other things between 4 people against one. And I know Snape treated Harry badly and I don't care.
