"You could tell from how those two girls acted earlier. They didn't want to leave at first, but once Miku infused her words with spirit power, they obediently left.
"As for why the two of us were fine, it might be because I have more spirit power than most Spirits, plus mental abilities.
"And you're immune to Miku's voice because you've sealed the spirit power of several Spirits."
"So that's why..."
Shiori nodded in realization.
"Wait—if Miku's a Spirit, shouldn't we hurry back and try to win her over?"
No sooner had Shiori finished speaking than Lingmeng gave him a light hand chop on the head.
"Ow..."
It didn't hurt at all, but Shiori instinctively covered his head with his hands anyway, looking at her in confusion.
Lingmeng could only give him a helpless, wry smile.
"If we go back, she'll devour both of us... What she said just now made it obvious she wanted to take us home, then use her ability to trick us into bed for a threesome!"
"Ah... uh..."
The corners of Shiori's mouth twitched slightly, as though he had no idea what to say.
Lingmeng went on to add,
"Besides, she still doesn't know her ability doesn't work on us.
"If we just go back, do we play along, go to her place, and get down and dirty with her?
"Or do we come clean and tell her we're done pretending? That's another problem~
"Anyway, without support from the Fraxinus, we'd better not approach a Spirit on our own."
"So, in other words..."
"Yep~ Of course we're going to cheerfully stand that idol up! Let's make a run for it while we can!"
Shiori looked hesitant.
"But wouldn't that make Miku really angry...?"
"Between Shiori-chan's chastity and Miku getting angry, Shiori-chan's chastity obviously matters more!
