It was certainly an interesting collection of notable names that had come to visit Akyuu. Yuuka had smiles at the approaching group, with every intention of turning them away if they lacked a formal appointment. What else was a good gatekeeper to do? Sadly, the lady of the household herself had come out to put a quick stop to her fun, and thus followed everyone inside to find out just what was going on today.

It was certainly an intriguing Incident, with Yuuka pondering silently by herself, her folded parasol hanging from the crook of her folded arms. Documents chronicling past events, Gensokyo's history, were being altered. Memories were unaffected, but the woman with abilities tied strongly to history was also out of commission. The flower youkai was... not particularly concerned, in all honesty. Whether these logs had been filled correctly or not hardly mattered to Yuuka, she could remember her own past well enough. That said... this was an Incident to resolve, and it had been a while since she had gotten involved in something she had no immediate resolution for. And given this unlikely gathering, it could make for a surprisingly fun afternoon.

"...Her enthusiasm is infectious~" Yuuka chuckled once Koishi skipped out of the room - or view. Smiling politely towards Akyuu, she said, "I'd very much like to assist our guests in this matter, Hieda-sama~ Worry not, once this business has concluded, I'll return so we can have a lovely chat~"

And with that, she exited the room, following after the cheerful satori.
