The reason why Tohru keeps trying to feed Kobayashi meat from her tail
It is considered an intimate gesture among dragons to feed each-other meat from their tails (they have a magic healing factor), so Tohru wants Kobayashi to eat meat from her tail because she in love with her. Fafnir's roughly humanoid "demon" form in his first appearance in the series is that of a corrupted dwarf.
Why Fafnir doesn't seem to be that addicted to his treasure hoard
There could be three possibilities which could explain why Fafnir does not seem concerned with his treasure in this series.- He has mellowed out from his past self, when he was addicted to his wealth.
- This is a case of Sadly Mythtaken, as Fafnir's obsession with his gold hoard was actually overly exaggerated in the human world.
- He keeps his treasure hoard in a Pocket Dimension that only he is able to access, therefore he can always protect his precious wealth.
Lucoa is a fusion between the original Quetzalcoatl and Quetzalpetlatl
Originally there were Quetzalcoatl and Quetzalpetlatl, but after the Brother–Sister Incest, they lost their divine titles. Both deities were fused into one (either as part of the punishment or due to another unexplained incident) which created the current Lucoa. If these two were fused, it would explain why Lucoa has heterochromia.Miss Kobayashi's Dragon Maid and Gabriel DropOut takes place in the same world
Both shows feature the Abrahamitic god as a background character (Tohru calls him a bastard in the Christmas chapter of the manga, and Gaberiel Dropout features heaven and hell), the existence of other religions (Tohru talks about Shiva, a Hindu god, and Gaberiel features a chapter where the girls visit a shrine) and the existence of dragons on both worlds (which is shown is both shows with Kobayashi as a definite examples of dragons, and Gaberiel showing a brief shot of Gaberiel's sister taking down a dragon in the anime).- It might help a little bit that both animes are comedy-oriented as well.
Tohru hates young-earth creationists
Given they claim to be followers of the Abrahamitic God and make up lies about dragons (that they're dinosaurs that survived), how could she not? Mister Magatsuchi is aware of Azad's plans
Mister Magatsuchi is a well-informed and powerful wizard. He likely keeps up to date on things happening in the Dragon world by various means. He learned of Azad's plan to play both factions against each other and so had Kobayashi join Shouta to that magical academy to help awaken her magical talent further so she could provide aide to stopping the conflict Azad is creating. Saikawa’s love for Kanna is based off the love the Spirit Natsumi from Date A Live has for Yoshino.
Both of them have serious Cuteness Proximity for the objects of their affection, and both have declared a desire to marry their respective crushes. I might just be trying to make something out of a mere coincidence, though… Each of the Other World characters that took up permanent residence on Earth represents one of the seven deadly sins, and the time they spend on Earth is helping them overcome said sin.
In order of appearance, Tohru represents Pride, as her story mirrors that of the biblical Lucifer, having challenged God to a battle and lost, subsequently being cast down and finding herself at the mercy of those that she looks down on. In addition, she also has a large ego and frequently talks about how others are beneath her. Since Kobayashi came into her life, she has now willingly entered a more subservient lifestyle and learned to treat others as equals. Kanna represents Envy, as she desperately wanted her father's affection, which she could not have, and went to self-sabotaging lengths to get his attention when she couldn't have it. Since joining Kobayashi's household, she has received the loving family she always wanted and become far better-adjusted, even managing to confront her father in a healthy manner and resolve their past conflict. Fafnir represents Greed, as he spent his life hoarding and protecting his treasure and has stated that his only goal in life is to continue to do so, though now he has expanded the definition of treasure to include Takiya, for whom he has gone out of his way to do nice things and find common ground. Lucoa represents Lust, being an exhibitionist and implied pedophile, though in later chapters she does begin to wear more conservative outfits and take Shouta's feelings into account. Elma represents Gluttony, obsessed with food and eating almost constantly, though as she continues to live on Earth, there are several chapters where she makes an effort to learn some self-control. Ilulu represents Sloth, as when we first meet her, she lashes out at Tohru, not knowing how else to express herself, and upon joining Kobayashi's household, spends most of her time sleeping until she is told to get a job, at which point she develops a respectable work ethic and becomes popular with local children. Azad represents Wrath, as he instigated the war between the dragon factions in revenge for them having slighted him, and though he hasn't spent much time on Earth yet as of this writing, it is implied that Georgie will be a positive influence on him. The trio of otherworld creatures to whom Tohru speaks (and frightens) at the convention are in fact Kobayashi's three noisy neighbors.
The lady who makes oddly loud noises while allegedly cooking is the witch, as we never actually see what she is cooking or what methods she uses that would produce such noises. The death metal vocalist is the fishman, as both feature the color green on their person and have sharp teeth. The most obvious one is the woodworker being the Oni, as both have the same body type, hairline, and facial structure. Kobayashi will somehow become a dragon in the future.
Be it through reincarnation or some form of unknown result of long-term exposure to so many dragons at once. Or the tail meat, which Toru will finally convince her to eat. The series will end with Kobayashi's first name being revealed and her finally trying some of Tohru's tail meat.
Azad's sister is the Bandit Girl (Chapter 118 spoilers for those who didn't read it yet)
In the final panel of said chapter, we get to see how Azad's sister looks like. She resembles Saikawa. Guess who also resembles Saikawa? The Bandit Girl. My theory is that Azad's sister and the Bandit Girl are the same person. It could be that the siblings are separated due to a dragon attacking Azad's village, leading to his Start of Darkness.Either that or Bandit Girl's resemblance to Saikawa is Foreshadowing to the new chapter.
As an adult, Shouta will be impossible to seduce
Lucoa herself has stated that she wants Shouta to be more comfortable around girls. That will eventually work, but maybe not as she plans.
As the series stands, Shouta is growing up with a Hot Goddess who has few inhibitions regarding human fashion. She also showers him with physical displays of affection while claiming to be his older sister. Because of this, he will genuinely start to see her as a surrogate elder sister, an annoying elder sister whose antics embarrass him, but still someone that he feels purely familial fondness towards. He will become so used to her antics that he will be inoculated against them. As a teenager, he won't bat an eye himself. Instead, he will start calling her "Succubus" as nickname.
And because Lucoa sets the bar so high, any human girl who fancies him will have to try other routes to get his attention, perhaps asking him about magic.
