You catch Reimu’s eyes, and motion for her to start interrogating.

“Alright, kiddo. What is the kamaitachi’s plan?”

The youkai takes a breath. “Manipulate the weather, lure humans into the forest, capture them, and use them to lure the Hakurei shrine maiden to us.”

“Why?” you ask.

“…To defeat her and prove the superiority of the kamaitachi to Gensokyo.”

“… Is that it?” Reimu asks after a minute, frowning. “If they want to try defeating me, all they need to do is challenge me to a spellcard duel. I’d be happy to oblige.”

The youth looks to the side.

Reimu’s mouth gapes slightly in dull horror. “…They don’t intend for me to live, do they?”

You move to touch her shoulder. Before you can do so, however, she grits her teeth, balls her fists, and a faint (holy, you’re sure of it) aura shimmers around her. “Those thrice-damned idiots! Are they insane?!”

“Reimu, calm down—“

She turns to you, fire in her eyes. “Wallace, if I’m killed without an heir, Gensokyo will instantly collapse!”

“Wait, what?” You’re not sure you heard her right.

“When Gensokyo was created, the Hakurei border was linked to the souls and bloodline of the Hakurei priestesses. Our lives are what stabilize the realm— in order to facilitate this, the border will prevent death by illness and other natural causes until an heir is produced, at which point the burden shifts to them. But what it doesn’t do is prevent unnatural death— such as at the hands of a living being. Which was the entire reason I started the spellcard system in the first place— so that youkai could challenge me without putting Gensokyo in jeopardy !” She turns to the weasel. “I know that the kamaitachi are recluses, but the clan elders have to know that my death is prohibited! It’s been common knowledge for nearly five generations!”

“…They do. And they’re against this plan.” He looks more collected, now. “About three months ago, our chief went into hibernation. He’s extremely old, so it takes him longer to wake up then it used to. With him out of commission, though, the leadership role fell to his eldest heir— currently his grandson, who shares the role with his twin sister. And they’re the ones who started all of this.” He sighs. “Tatewaki and Kodachi are extremely ambitious, and are not satisfied with living in the forest. They’re also incredibly charismatic, as well as unwilling to accept what they don’t want to acknowledge as truth. They’re convinced that the tales of the Hakurei clan’s life being tied to the realm are false, and they’ve managed to convince a good portion of our people of that as well.”

“…So they’re delusional.” Reimu mutters.

“…Very.”

“Well,” you say, drawing their attention. “What’s the plan, then?”

“What else?” Reimu says, cracking her knuckles. “I’m going to put a stop to this. He,” she says, gesturing to the youkai. “Is going to lead me to the village. Then I’m going to explain to ‘Tatewaki’ and ‘Kodachi’ just how very cross I am.”

“…You’re forgetting something important.” She looks at you, confused, and you continue. “I’m here as well. It’s not you, it’s us. I’m not going to let someone I consider a friend walk alone into hostile territory— my parents raised me better than that. I’m coming too.”

“That’s…” she trails off, and shakes her head, smiling. “…You’re right. I’m sorry.”

“Good. Also…”

[x] Write-in.

Some things to keep in mind for the write-in:
How will your group enter the village? It might not be so simple as having your little friend lead you in.

Speaking of which, what’s going to happen to him, now that he’s actively going against his people’s plans? Is that even an issue?

Also, how did they pull off this weather shebang? But now, in the face of this plot, does it matter?
