@SomeDuder I think giving him an overpowered pet helped in making it very unlike any other isekai. Mostly because it is not made to praise the main character. Feru is made fun of much more than it is shown on a good light.
Plus, without Feru we would like character's interaction since Sui is not the most talkative character and any other character is temporary.
Plus Feru and the gods help a lot at desacralize this fantasy world and its "faith". Both Gods and legendary beasts are simple gluttonous beings.
Without Feru, it may have been much closer to a traditional isekai story with cooking as an overpowered ability to sway anybody (otherwise, not a chance he would have survived).
It is clearly not an adventure based on battle but rather on story and jokes. Some sort of "Slice of life x Fantasy"
ps: Sorry about the formulation, the mistakes, etc... not my first language, you know the drill
