Who cares about suffocating!

The biggest problem here...

...is how long that waterproofing magic will last!

If the waterproofing on those books runs out...

...then even I might snap for the first time in decades ♡

I have an idea!

First, I'll throw a Gungnir at the wall around that bookshelf...

Isn't that exactly how this all started!?

Patchouli! Couldn't you use your Water Sign...

...and control all that water?

...That's impossible.

The water coming in is from the lake, right?
