Greetings, my name is Patchouli Knowledge. I am the librarian of the Scarlet Devil Mansion. I am usually just at the library because of my passion for books. Due to ashma and poor health, I rarely leave the mansion. I am also a very powerful spellcaster controlling elemental magic. I have been given nicknames as the Great Unmoving Library and the Wizard of the week. I once constructed a rocketship to get to the moon.
