It has virtually no story nor build up and fails to build up to an end goal. To some degree, its first few chapters make you think "what exactly is the end goal to all this?" Every chapter just seems to have the main cast doing repetitive odd jobs around town and none of the characters seem to be interesting enough to catch anyone's attention. Furthermore, its fights are relatively bland, quick and straightforward. Are these all necessarily bad things? No. There are various series like Gintama and Mob Psycho (Web Comic) for instance that tended to focus on odd jobs and seemed to lack a story and interesting characters in their early stages but made up for the lack of those through other means.
Gintama made up for that through its comedy and Mob Psycho made up for that through its relatability to its younger audience. It is also worth noting that both these series ended up having great stories and well developed characters later on.
But what exactly does Tokyo Demon Bride Story have that makes up for its lack of story and interesting characters? It's extremely lacking in the comedy department with its dependence on already overused Shonen Humor tropes. Despite having an implication of a marriage in its title, it also fails to build up any sort of romance. In fact, the "bride" relationship you come to expect is more akin to a stalker and victim one sided relationship that was caused by a childish promise that half the parties can't even remember. It lacks any sort of relatability due to its bland characters and to be honest, it's hard to see any qualities that makes it stand out.
It could be good as a Slice of Life series but as mentioned earlier, it fails to have a unique X Factor aside from the presence of demons that makes it stand out as a slice of life series. Perhaps Slice of Life fanatics would find enjoyment in this series but personally, I feel that there are much better SoL series out there than this one.
Overall, Tokyo Demon Bride Story is a series that does not know what to focus on and as a result fails in all the aspects it attempts to be. I think that if it chooses to focus on one aspect and executes that well then it may have a chance at survival. Particularly either a proper romance or comedy (or even both). It could also have a shot at survival if it decides to switch to being a battle shonen however a battle shonen about fighting demons has already been done countless times in the past (Yu Yu Hakusho and Demon Slayer for example). If it keeps up at its current rate however, I cannot see it surviving past 30 chapters. To me, this is probably the weakest link in the current WSJ roster thus far.
