Bonus: Lazuli 1
Before Stage Start
Kyubey: Go through the dimensional hole.
Mami Tomoe: ?
Homura Akemi: Kyubey, you knew everything. Didn't you?
Kyubey: Yes. I was watching you the whole time.
Kyubey: Ever since you came to this world.
Homura Akemi: Why didn't you tell us anything?
Kyubey: Hehe, I have my own objective.
Mami Tomoe: And what would that be?
Kyubey: You'll find out soon enough.
Mami Tomoe: What does that mean...?
Homura Akemi: Tell us what this "dimensional hole" is.
Kyubey: ...One day, a dimensional hole appeared at a singularity in space-time between this world and your world.
Kyubey: The two spaces are connected via this hole. That's how you wound up here.
Kyubey: Your temporary amnesia was a side effect of passing through the dimensional hole.
Homura Akemi: ...
Kyubey: And you already know what happened next.
Kyubey: Mami lived as a Killer Princess, and Homura just played along in spite of her misgivings.
Homura Akemi: Could we go back through the dimensional hole, and return to our own world?
Homura Akemi: Show us. Let's go back home.
Kyubey: Look over there...
Mami Tomoe: That's...
Homura Akemi: A dessert witch!
Kyubey: That's not good. The witch is guarding the dimensional hole.
Mami Tomoe: Then we have no choice but to fight.
Homura Akemi: Yeah.
After Stage Clear
Mami Tomoe: This is the dimensional hole?
Homura Akemi: It's fading away...
Kyubey: How unfortunate.
Kyubey: The dimensional hole has been converging on the singularity over the past several days. There's only a small residual hole left.
Mami Tomoe: What do you mean?!
Kyubey: It's not enough for you to travel through space-time. In other words, there's no way for you to return to your original world.
Homura Akemi: ...But we could have several days ago?
Mami Tomoe: What are you thinking of doing?
Homura Akemi: I'll go back in time, then escape this world with you.
Homura Akemi: ...What's going on?
Kyubey: What did you expect? You're not from this world.
Homura Akemi: ...
Kyubey: This world has its own set of rules.
Kyubey: You can't recreate the timeline of this world. You could do it if you belonged here, but you don't.
Mami Tomoe: Then what should we do?!
Kyubey: You don't have any options. All you can do is live here, in this world.
Mami Tomoe: That's not funny! There must be another way!
