Yumemi: "So, I wasn't able to defeat real magic after all... How frustrating! Why wasn't I born in this world?! Now that it's come to this, I'll show you the true power of SCIENCE!! Take this! My Planet-Destroying, Fourth-Dimensional Positron Booomb!!!"
Well, I have no other choice. I will give up on learning magic. But, I was able to collect quite a lot of data, and I can present a report to the Academy. "Magic is real! Closely related to religion, can solve our energy crises and environmental issues. It will save humankind! And...""
Chiyuri: "Somehow, that seems off..."
Yumemi: "Anyway, a promise is a promise. I will give you whatever you desire."
Marisa: "Hmhmhmhm...♥"
Yumemi: "...But only within reasonable limits."
Marisa: "Hmhmhmhmhmhm...♥ What kinds of things can you do?"
Yumemi: "Um, well... you know..."
Marisa: "I seeee... Well, what if I want you?"
Yumemi: "Denied.💧"
Marisa: "Well, how about Chiyuri?"
Chiyuri: "No way.💧"
Marisa: "Come ooon! Aren't you going to give me anything?"
Yumemi: "Ugh. No way around it, huh? I shall become yours for a juuust a little while...💧"
Marisa: "Weirdo. I don't want you!"
Yumemi: "...💢"
Marisa: "Come on, I was only joking... Anywaaay. What I'd like is a weapon."
Yumemi: "Come again?"
Marisa: "Like, something that can be used even without magic. I want a weapon from your world."
Yumemi: "Very well. This can be easily arranged. OK, it's waiting outside. And with that, we are off."
Marisa: "Alright, that works!"
Yumemi: "Well then, may we meet again someday!"
Reimu: "Hey, what in the world are you riding on?!💧"
Marisa: "Oh, this? Her name is Mimi-chan. She's a weapon called an ICBM."
Reimu: "A weapon? How do you use it?"
Marisa: "Not a clue. But isn't she cute?"
Reimu: "R-really? Well um, that's..."
Mimi-chan: "Kyuuuuuun!♥"
