In Xanadu did Kublai Khan
A stately Pleasure-Dome decree,
Where Alph, the sacred river ran
Through caverns measureless to man
Down to a sunless sea.
Toyohime could not let herself feel pity for the two men staring at her arrival amid the peach trees. She couldn't let herself think about what this meant for her, her home and the poor souls before her. That would only make things worse.
It helped that their spacesuits made them featureless and kept them from talking.
As the lead figure raised his hand in greeting Toyohime called upon her powers to summon the god of calamities. With the tiniest amount of the gods power the violent materials the humans used for their crafts fuel went out of control. There were a lot of fail safes of course, but against divine intervention even a miniscule chance became near certainty.
The craft began blaring warning signals, and the two intruders turned towards it, probably in shock. Toyohime couldn't be certain, but she imagined they were even more surprised when their surroundings vanished and they appeared somewhere else, on the 'scientific moon.'
She turned to her sister. "Is it taken care of Yorihime?"
Yorihime closed her eyes then shook her head sadly. "Sorry. The humans are gone, but this area's border is too weak, and it's been contaminated. We'll need to cleanse the area and pull back."
Toyohime looked at the beautiful orchard and shook her head again. "We can't keep this up. We're losing too much ground."
Yorihime simply nodded. Toyohime had noticed that her sister hadn't been smiling as much recently. Then again there hadn't been much to smile about.
Sighing Toyohime ran her hand along the trunk of one of the trees, as a wordless apology, before calling on her power again. "Kagazuchi."
The trees all burst into flames, as the god of fire was unleashed upon the garden. Soon there was nothing but ashes that blew away as the atmosphere began to leak.
Yorihime waved over Reisen, her emissary. "Eliminate everything else then return to the city and pack for a meeting with Eirin."
"Um, sure." The moon rabbit replied. She began pulling out the artifices that would make this former part of the lunar capitol indistinguishable from the dead moon surrounding it.
"Let's take the quick route home," Yorihime said waving her fan.
"Sure thing," Toyohime stated. She was tired, and there was a lot of work to be done before she could rest again.
Still she looked back at the tracks in the dirt that the human's lunar rover had made. "I didn't think we'd have to use that plan this soon," she muttered.
This is, unsurprisingly, a continuation of A New World: Book 1, which is available here or on shrinemaiden. While that story can work as a standalone piece, how and why Maribel and Renko arrived in Gensoukyo is explained much better there.
