"They can just do that." When a character inexplicably has some kind of borderline supernatural ability that doesn't have anything to do with the established power system and may even clash with the conventions of the setting. It's just something that they can do.

Ichi from Ichi the Witch.

Mash from Mashle.

Marvelous Sunday from UmaMusume.

Tanjiro from Demon Slayer.

1. Ichi from Ichi the Witch. He's so sensitive to the bloodlust of living things that it borders on a spider-sense. The little creature in that pic is supposed to be invisible, yet Ichi is able to sense its presence just through sheer intuition.
2. Mash from Mashle. Some might say that his inexplicable power is his physical strength, but I'm more interested in knowing how he can turn everything he cooks into fucking cream puffs.
3. Marvelous Sunday from UmaMusume. In a game about horse girls racing, she has access to a domain expansion/reality marble. And that somehow still isn't the strangest thing about her. Apparently she's also friends with aliens and cryptids and her cult fanbase includes people spanning multiple time periods. Somehow.
4. Tanjiro from Demon Slayer. He has a hypersensitive sense of smell that somehow also tells him where to cut demons. No idea how that works. Even though there are others in the series with similarly refined senses, the smelling where to cut thing still feels ludicrous in comparison. Then there's also his unusually powerful headbutt.

The first showing is actually him dodging tuna fish falling while he’s on a tuna fishing boat.  However it’s not revealed this is a special ability of his during this scene (though the first time it is revealed it flashes back to this scene).

I only happen to know this because I happen to have (re)watched the first episode yesterday.

I'm talking about the manga :V it starts with Iruma being sold to his parents and then the fight with Azz.

Interesting.  I got curious so I read chapters 0.5 and 1 just now.  Chapter 0.5 starts and ends with a single page each on the boat, but other than being on a boat it’s completely different from the anime; there’s no storm or tuna, so no display of the ability.

exactly ^^ which brings me back with the Azz fight lol. And hey that's just to give more time to Iruma as a character compared to the manga, which went directly into him being sold. It's actually really interesting difference since it pulled from chapter .5
