In Summoner’s Legacy, you’re a descendant of the occultist Aleister Crowley. You also have a strong interest in the occult. You encounter a sexy futa in the shower of your school, and you’re overcome with lust. You lose control over your actions, and that’s when things take a turn. You find a piece of paper tucked into your shirt pocket with the instructions to go to a local bookstore. You find an old book that is possibly demon possed. You take the book home and discover how sinister it is.
