Yotsuba, don't be afraid of the library. The tower is only at its most dangerous at night. There are often many people during the day that will help you in case a monster does show up. Did you go to the library by yourself? You should always travel with someone if you may be staying until night, especially with the new monsters about this month

But I am glad you met Lucifel. He is a very good friend of mine. I assume he helped you? If you are ever in danger and you see him, go to him for help. He can help you escape quickly.

Tell Little Yoba and Juralumin hello for me, then.
