You, Twilight, Spike, and Tohru had Lucoa come over. 

(Y/N): Oh, hey Lucoa. 

Twilight: What's up? 

Lucoa: Well, we need to talk. And I figured you four would be the most willing to listen. 

And so... 

Spike: You're living here in this world too? 

Lucoa: I stop by your place a lot, so I figured I should crash here. I'm even living with a human, like you guys are living with (Y/N)! And I also need some things to clear up. 

Twilight: What do you mean by that? 

Lucoa: I was on my way home after visiting you one time, but then someone seemed to summon me. And- 

Much later... 

You all were walking with Lucoa. 

Tohru: YOU GOT SUMMONED BY A CHILD WHO PERFORMED A RITUAL OUT OF CURIOSITY?! AND YOU EVEN ACCEPTED HIS REQUEST TO BE HIS FAMILIAR?! 

Lucoa: Yep! That's right! I'm living as his servant! 

Twilight: And what do you want to clear up? 

Lucoa: He thinks I'm a demon. I want you guys to talk to him and tell him I'm not. 

(Y/N): Okay! Sure! 

Spike: That shouldn't be too hard. (sweatdrop) At least I think. 

Lucoa: Great! 

At the house... 

You all sat down. 

Twilight: Lucoa. 

Lucoa: Yes, Twilight? 

Twilight: If you're supposed to be the same goddess as in the legends, then why are you hanging around here instead of- 

Lucoa: Technically, I'm a former goddess. 

Twilight: What? What happened? 

Tohru: She got drunk with her friend, violated her younger sister, and got expelled from her throne. 

(Y/N), Twilight, and Spike: WHAT THE HELL?! 

Lucoa: TOHRU! WHY DID YOU SAY ALL THAT?! 

(Y/N): Changing the subject completely, you're a demon? 

Lucoa: NO! I created civilizations, and culture! Demons wouldn't do that! I prefer to be called a venusian! 

Spike: And this kid. What about him? 

Lucoa: His name is Shota, and he's kind of a cautious one. I tried everything to get closer to him. I snuggle with him, and I even take baths with him! But none of it ever works. 

Spike: That is ... geez ... personal space much? 

Shota then appeared. 

Shota (A young boy who is a descendant of magic users! He tried to summon a demon when he ended up getting Lucoa!) 

Lucoa: Hi Shota-Baby! Welcome home! 

Shota: B-BAD DEMON! You can't go doing things like this without permission! You're trying to gather your friends so that you can take over my house! 

Twilight: Aww, it's cute how he's trying to show off authority. 

Lucoa: I know right? Isn't he the cutest thing? Sorry Shota-Baby!

Shota: (blushing) A-As long as you understand it's fine. 

Lucoa: The truth is, I called them here to clear up a misunderstanding. 

Shota: And that is? 

Lucoa: I'm not a demon, I'm a dragon. 

Shota: But I performed a demon ritual. 

Lucoa: I thought it would end badly if you summoned an actual demon, so I intervened. 

Shota: But I don't have enough magic to summon a de- WAIT, YOU'RE TRYING TO TRICK ME! 

Lucoa: See? This happens every time. 

Tohru: Shota, you appear to be a wizard. But why were you performing a ritual? 

Shota: I want people to respect me. Wizards are living peacefully in Remnant, but we will have to go back to our original world someday. We have to maintain our power level in order to succeed our superiors. That's why- 

Twilight: So, you summoned Lucoa in order to show off your power? Ouch. 

Lucoa: Huh? 

Shota: Now that I think about it ... even a demon would be troubled if it was summoned at a random time. And there's no point in them staying with a kid like me. Sorry, Lucoa. 

Lucoa: Look, it's not like I want to go back! 

Shota: Really? 

(Y/N): Look, if you really want to stay with him, then you have to at least do something. 

Spike: Yeah, Twilight and I go on adventures with (Y/N) and the rest of our friends. 

Twilight: And Tohru is one of the maids of the mansion. 

Shoat: Well, my Mom does all the house work. 

Lucoa: So, I have to do something in order to keep living here? 

Shota: Y-Yeah. 

Lucoa: How about a hoard of precious gems? 

Shota: My Dad knows alchemy, so no thanks. 

Twilight: Alchemy? That sounds really interesting! 

(Y/N): You want to learn alchemy? 

Twilight: It's kind of like magic, right? 

(Y/N): I guess. Maybe we'll be able to learn it eventually on an adventure. 

Lucoa: How about I teach you how to farm? 

Shota: No thanks. 

Lucoa: Then I offer ... my body. 

Shota: AAAAAAAAAAAAAAAAAAAAAAAAAGH! I KNEW IT YOU'RE A DEADLY SUCCUBUS! 

He ran off in fear. 

Lucoa: SHOTA-BABY COME BACK! 

(Y/N), Twilight, Spike, and Tohru: You did that to yourself. 

Later... 

Shota had ... an interesting dream that night.
