Really cute

Absolutely beautiful

Good to see that hosen is still making such masterpieces

-Nails as large as a human arm
-Kosuzu stuck to a pictureframe(?) by those nails
-Akyuu hammering said nails in
-Reimu stuck in an adjacent pictureframe(?) by similar looking nails
-Similar-looking pictureframes(?) all around, at least three of them have people inside

Okay, I don't think I want to know what's going on...

This is a reference to the album cover of 音 and a reference to the song 忘らるる物語 from the same album. It's not creepy, rather sad.
