Fridge / Knights of the Otherworld

• A weakness the story has is not seeming to realize how introducing superheroes battling monsters and villains changes the narrative. For instance, like in Ever After High, Wonderland is under a curse and its people can't go back. However by making Lizzie's boyfriend a Kamen Rider, Knights of the Otherworld gives the Wonderlandians a powerful champion who travels to another world all the time to fight evil. Who's friends with a legendary wizard and an army of other powerful champions. Even with how common a hero breaking a curse is as fairytale plots go, the story doesn't even suggest asking the Knights to look into helping with this problem for the longest time.
• A big plot motivator for the early part of the story is the knights trying to save their girlfriends from having to live out their parents' destinies, to the point of Arthur threatening Headmaster Grimm with his Rider powers on Legacy Day. Then it spends the next two chapters having the knights meet their girlfriends' parents, practically all of whom are happy, successful and well-adjusted royalty. Only a couple of them having gotten bad endings, and even those are seriously downplayed. ^note  Ginger Breadhouse's mom is extremely nice, she wasn't burned to death in her own oven. It's commendable the knights want to save their loved ones from having to go through scary stuff, but it turns into a fair bit of Narm when they're determined to save their girlfriends from their parents' destinies, but practically all those parents are shown to be doing extremely well.
