Cirno also appeared as Letty's sub-boss in Perfect Cherry Blossom.

I'm more concerned with the 'let's sleep together' thing Letty said.

Hibernation.

And, Cirno was right, but she was one game off.

Sub-boss? More like a 15-second-lifetime fairy, amirite?

On Hard and Lunatic, she has a spellcard.

The spellcard kind of equals to Letty's non-spell, so her actual appearance is just... meh.

All this time later and Fairy Wars comes out...

QFT

The dialog sounds like the author expected PCB to be Cirno's last appearence.

Then comes PoFV, UNL...

Hilarious in Hindsight?

Well she did in the last game.

The description for saigyouji_yuyuko_(living) says that it applies to depictions of her living body before her death, and of her backstory suicide. Does that extend to her disinterred, skeletal corpse? I'm thinking of adding it, but want to make sure it fits, even by a stretch.
