So they have airships, and a month's operational cost in fuel alone is tens of billions...? Even if that's JPY, that's crazy inefficient.

I kinda assumed from the fact that it's set in Minato Ward, Tokyo, non-hunters dress in modern clothes, the presence of PCs, cell phones, wind turbines that generate electrical power, LCD billboards and traffic lights, etc. that they had modern technology. A standard blimp or jet aircraft does not take hundreds of millions of USD to operate for a month.

Even if airships are super high performance luxury craft, the numbers don't seem right to me.

I mean it might seem so but something comparable could be the Hindenburg which costed around 5,07,600 usd to operate for 60 hours (ticket cost fully loaded) so take of about 20%+50% of markup cuz rich people toy. The ship is prolly wayyy heavier than the Hindenburg so it seems rather reasonable. Though ofc using nuclear means to get energy is wayyy more efficient and using something more appropriate and realistic to fly around like a jet or a helicopter. Also not to forget the weight savings coming from such a small piece to get energy instead of a fuel tank.

Ticket cost is nowhere near operating cost. Airfare is not a for-cost charity.

For example, a fully loaded 747 costs about $6,240 / hr in fuel. A mid-haul flight is around five hours (most flights are shorter, but I'm trying to use figures most generous to your case). At a conservative estimate, they seat around 500 people, and an average ticket is about $350.

That's a $175,000 ticket cost fully booked, despite the fuel cost being $31.2k, a little more than 1/6 the revenue.

Hundreds of millions of USD just for fuel is not plausible.

Also, you seem to have a comma out of place; the adjusted-for-inflation ticket cost for a fully booked Hindenburg should be around $500,000. Even IF we assume ticket prices match fuel prices AND tack on 50% markup (despite the Hindenburg already being priced in as an analogous rich people toy; people during the Great Depression did not generally have $10k inflation-adjusted to spend on a single trip), the Hindenburg would have had to make ~133 trips in a month to have comparable expenses. This is impossible for hopefully obvious reasons.

Rechecking that message in Google lens gives "the size of the wind magic stone this time is probably worth several hundred billion yen"
Siennas message also comes to "With a magic stone of that size, would the ship be able to operate for a month?"

So idk maybe they live in a world of hyperinflation

Oh, we're back at the adventure of the dummy who keeps nearly getting killed off.

I worry about what he's going to end up doing with that stone...

Between the mentioned resource scarcity (=unknown fuel cost), unknown airship weight, and unknown money value (though it's fair to assume today's value for this), it's not necessarily inefficient

True, there are too many unknowns to say it's inefficient.

It's definitely not even close to competitive with non-fictional aircraft, though, and it seems bizarre to me that they live in a world otherwise indistinguishable from modern Japan, yet lack said aircraft. Or that they have both modern non-fictional aircraft and fantasy airships, yet airships are prevalent enough that an average person would understand an economic explanation couched in airship terms.

Ad hoc explanations can be made, of course. Maybe people in this world take climate change seriously, and are willing to pay hundreds of times more for a zero-emissions method of flight. Maybe they never discovered fossil fuels (though they seem to have plastic and other petrochemical products, so that's dubious). Maybe they're all huge fantasy nerds who are willing to pay an insane premium to see a sailing-style ship in the air.

Honestly, manga authors like to throw around big numbers without really thinking about them, and I'm inclined to think that's all that happened here. The author's intended point was just "even one of these would make you rich if you can get home".

I don't want to belabor the point, so I'll stop banging on about it. Sorry to anyone annoyed by my nitpicking.

No worries, I wasn't doubting the translation, just that the author properly thought that through.

In chapter 2 we see him commenting on ¥400 for a 500ml bottle of water as "tourist attraction prices". Actual conbini water prices seem to be about 100-400円, so the currency itself is probably not massively devalued.
