Author's notes: This isn't really a single story, but a collection of what-ifs I've been thinking of. I'll also upload chapters that combine multiple what-ifs that have already been uploaded here. Also, I'll be writing these in a different way from my other stories, but this doesn't mean I'm changing my standard writing style, this is just an exception.

Disclaimer: I do not own any of the characters in any of these what-ifs, this is simply my interpretation of what would happen.

Update: Added a condition to view this scene so that later scenes in this What-If make a bit more sense.

What-If 1: Reimu, Touhou Project, Part 1

Event Conditions: Must have obtained Poppi QTpi.

Location: Land of Challenge

Rex and the gang returned to the Land of Challenge, intending to complete more of the Nopon Archsage's challenges, but when they got there, they noticed a black-haired girl wearing a red and white foreign-looking outfit talking with the Archsage.

Rex: Huh? Who's that?

Nia: Perhaps someone else the Archsage brought here?

Tora: That most likely scenario.

Rex: Well, in that case, let's go meet her.

Rex walked up to the Archsage and the girl, with the rest of the group following behind.

Rex: Hello, there.

The girl turned to look at Rex.

Girl: Ah, hello. Would you happen to be that "Rex" guy that the Archsage told me about?

Rex: Yep, that's me.

Girl: The Archsage told me about you and your friends, so there's no need for you to introduce yourselves, though I suppose I should introduce myself. My full name is Reimu Hakurei, but please call me by my first name, Reimu. I'm a shrine maiden from a place called Gensokyo.

Rex: Shrine maiden?

Reimu: I'll explain what that is later.

Nia: Well, it's nice to meet you, Reimu.

Reimu nodded toward Nia before turning back to the Archsage.

Reimu: About what we were talking about earlier, I find both the roles of Drivers and Blades interesting, but I don't think I'll fit the role of Blade that well. Is there any way I can be a Driver instead?

Archsage: Of course! Nopon Archsage predicted this, so already created items!

The Archsage pulled out what looked like a red Core Crystal.

Rex: A red Core Crystal?

Archsage: Since Reimu cannot resonate with standard Core Crystal, Nopon Archsage made special Core Crystal specifically for Reimu. Just hold and focus on Core Crystal.

Reimu: I see, thanks.

Nia: So only Reimu can use that Core Crystal? I guess that explains the color, you'd need a way to tell it apart from normal Core Crystals.

Reimu grabbed the Core Crystal and held it up to her face with a tight grip while closing her eyes. The Core Crystal started to glow brightly, but the light dissipated quickly. When the glow dissipated, a new female Blade that almost resembled Reimu was standing next to her, but the Blade was holding some sort of sword.

Blade: Greetings, I am known as Meina. I look forward to working with you, miss Reimu.

Archsage: Archsage give red Core Crystal for free, but Archsage have two more different-colored Core Crystals that Reimu able to use, which Reimu must clear challenges before obtaining. Challenges are designed to help Reimu practice as Driver. Clear both, and Archsage also give item to let Reimu travel to Alrest.

Reimu: Fair enough. Thank you.

Reimu then turned toward the group.

Reimu: Well, if it's alright with you, I'll be working with you from this point forward.

Nia: It's no problem at all. And we'll teach you the basics of being a Driver.

Tora: New friends always welcome!

Reimu gave a nod.

Reimu: Thank you. I appreciate it.

*To Be Continued*

Meina is a fire-element Blade who uses a "Miko Sword", which is basically a reskin of the Aegis Sword weapon type. The only reason I considered Aegis Sword as an option is because Meina is exclusive to Reimu, otherwise I wouldn't be using weapon types that are exclusive to specific characters. Actually, for that same reason, I actually wanted to avoid non-exclusive weapon types. As Reimu doesn't have an anchor like Rex does, Reimu's counterpart Art replaces the anchor with a large danmaku bullet from her game series and doesn't inflict topple.
