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!!!"
Yumemi "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!❤"
