The First Demon King's Chef in History

After a gentleman's summary, a single female protagonist with multiple characters will leave more feelings. It is relatively common for light novels (and otaku novels) with single heroines to do well (I am talking about Japan...). Of course, in fact, a small Shura field or something with three people or less is also cute. (Because this can actually better reflect the character's characteristics) And in fact, if the male protagonist of the stallion novel transfers most of his experiences with other harems to the female protagonist, there will be no shortage of articles, comrades! (Of course, if the single heroine theorem is pushed early, it will not be appropriate (help me). At this time, it will be better to have less than three heroines. But comrades who want a harmonious harem! Only when all the heroines have the same Mary Sue character will the harem be harmonious! Contradictions will inevitably arise with different characters. Many Chinese novels with harmonious harem heroines with clear characters will 100% feel inconsistent if you read them carefully!

The male protagonist and the devil signed a contract, and life and death were linked. In other words, he should be as important to the demon world as the Demon King. Why is there not even anyone to follow and protect him? Is the demon's brain flooded?
