I coincidentally bumped into the cover of a new light novel which is a reverse Isekai, where the hero summons truck-kun instead of the other way around.

I love how this is worthy enough to fit in the News forum

Absolutely groundbreaking.

So do they send Demon Lords to our world then?

Optimus Prime isekai?

So according to the linked article, Isuzu -- the truck company -- helped make or fund this book.

That's hilarious.

Lol this is hilarious thank mangadex news
