I hope there's more of this.
Just like I hope for more 'Serial Killer Reisen'

But, it'll probably end up the same way... Nada~

I think it ends here.
Sakuya has lost control over her power and gets stuck in time-stop for centuries while using it. If it's to serve her mistress, she doesn't care.

Ugh... painful.

Holy shit is this dark, sooooooooooooooo dark.

people that try to make touhou grimdark are annoying

Perfect and elegant till the end. For that, she deserves respect.

So...because she doesn't age while time is stopped she's spending insanely long amounts of time (whether it's because she's lost control, or doing it on purpose cause she's already insane idk)

seems she's lost total control of her time stop ability, and each activation lasts a whole century. She's not insane, what Eirin was getting at was getting stuck in a time stopped world for centuries will driver her mad.

You know, as you guys all put that together, it hits me. Until however much time passes by...

She'll be standing Right There. Literally.
Huh... I feel sympathetic, but, at the same time, charmed by her devotion.
