What I'm doing is avoiding coming to a conclusion because we don't have enough evidence and questioning what appears to be nothing more than a delusion or paranoia of the main character, which definition does that fit? Oh, that's right, none of them.
All of them. You decided he had a cheat because he used a sword someone weaker than him couldn't use.
I never said he HAS a cheat skill, I said he MIGHT, and only after
you asserted that he did not. The conjecture there is yours, by all three definitions, because you are making an assertion of fact based on your own guess with no solid evidence of your claim. My "conjecture" is an open-ended refutation of your assertation, demanding that additional information be provided before a conclusion can be made, which does not fit
any definition of "conjecture."
Then there's you, "Oh, we don't have any concrete evidence of this, but it fits with my own headcanon and appears to be true at a glance so it must be true."
I have no idea what you're talking about. I remember telling you that the Felice summoned the guy, that the others were specifically unshackled by goddesses, that the goddesses briefed them on their powers, among other things, and that MC doesn't have a cheat. One of those is an inference, and that's because it's a staple trope of the genre. The alternative is that they were dumped, entirely at random, without explanation, then independently discovered not only the use of magic, but their own specific brand of OP bullshit magic.
They cannot use any magic outside what their cheat grants? So, by extension, would Kyouya being able to use all kinds of magic prove he does have a cheat, since you initially placed an emphasis on the fact that the others could use magic at all as evidence of them having cheats?
Chapter 18. Dude is shown to only live for praise, but his biggest boast is that the townspeople called him a hero, if he had met a goddess and been told there that he was to be a hero then he would have opened his backstory with that instead of him falling on his ass when he was summoned.
Why would he be more impressed by a debrief when the first thing he sees in his new adventure is an entire town of people chomping at the bit to worship the ground he walks on? The bit is never that the gods praise you for being the guy. They're the ones that tell you you have a job to do. Or do you think the first thing she did was tell him how absolutely awesome he was? The people are the ones that see the good in what you do.
He views all the people in that world as NPCs, but the first one to call him a hero would have been the goddess. With as much as he loved being called the hero, at no point did he ever say that anyone but the villagers called him that, nor did he mention ever being told he was chosen. (as tends to be part of the trope you're clinging to)
Yes he did. It's the exact reason he's OP in the first place. Though it wasn't the one to summon him, as far as I know. But this is an apples and oranges comparison.
He actually did not. It almost sounds as you got as far as him hearing the voice and didn't read any further.
It is. Fantasy world A to fantasy world B is still isekai.
I'd check, but any discussion surrounding that series spoils every last detail of every last character and event for literally no reason. Also, I said "Involved when MC gets a cheat skill". I'm perfectly familiar with "Oh, I guess I came back to life. Let me work hard to get stronger". I'm talking about "Ooh, I'm The Hero. And I have a special cheat skill!" You know. Like in this story.
Still an isekai reincarnation series where the MC obtains cheat powers and does not meet any deity during the world transfer.
And for that matter, neither did the other summoned characters.
Sure, no gods, but no cheat skill, or "Hero" setting. Dude wasn't even summoned. Apples and Oranges.
Dude is a de-facto hero with super-cheat strength and intuition, he just prefers to pretend to be a pretend villain.
Wrong Way to Use Healing Magic
Oh right!
So you'll admit this one fits, but are denying others fit on the basis that their MC isn't the hero. Incase you forgot, this MC isn't the hero either, nor was he summoned to be one.
The one with the bitch? Did the guy get a cheat skill? All I know about the series is he gets tortured regularly for no fucking reason.
He gains the ability to adeptly use any "weapon" he touches.
If you really want to nit-pick about whether or not the MC is the hero, as you did with a few of my previous examples, you end up forcing the requirement that someone tells them that is their role and has the power to all but force them to fulfil it, which, would you look at that, ends up needing to be someone with stronger cheat powers or a deity. Otherwise, I'm fairly certain Isekai Walking, Instant Death Cheat, Aligned Seven, and Lv2 kara Cheat, among others, still qualify just by removing the "MC is proclaimed the hero" requirement.
All that out of the way, you STILL have not explained how Kyouya showing off his strength results in Felice being outed as a demon lord. They have no evidence to make that connection unless Kyouya or Felice provide that information themselves. From every shred of information we have, Kyouya showing off his strength shouldn't result in anything more than incredulous looks and jealous pressure. They have no way to connect Felice to any demon lord, they even already know that she exists and can talk from when they brought Kyouya in. The only information they don't have about the two that they could possible gather at this point is how strong Kyouya is, but they have no way to connect that to anything except the fact that he's a returner,
especially if his summoning was not through the goddesses.
Because he's the strongest returner ever? They already sort the returners by strength, so there was already a "strongest returner ever" before him, he just happens to be stronger than them. Because he's that strong without a [Savior Crest]? That still doesn't connect him to anything, that just means he wasn't part of the group that defeated the demon king, or that he got returned for other reasons. He has no actual reason to be holding back that we've been told about beyond his own paranoia.
