I am an elemental magician who serves the great Lady Remilia. My name is Patchouli Knowledge. You could also call me the Spirit Mage or Magic Sage―I care not. So, what do you want? I've already heard about people traveling between different worlds. I'm constantly analyzing the data and devising countermeasures. None of this is unexpected. I will protect my mistress. So, what do you want from me? ... You know what's going on? I see. Tell me more.
