That's Koakuma

Got it!

Let's go all quietly... Don't make a sound...

Quiet... quiet...

She moves around inside the library, so we have to be careful...

Ah! I just thought of a good idea!

Eh?

If we use these... we can be disguised!

Like this! If we stand next to the bookshelves like this, they won't suspect a thing!

No, I don't think that's going to work...

Ah! This book is full of pictures!

I can't read this, but it looks fun!

Hey, wanna let me see it for a bit?

Maybe going inside the bookshelf could be good!
