Hifuu Club Activity Record: The Sealed Esoteric History

Few people in the Outside World are aware of the secret world known as Gensokyo. Maribel Hearn and Renko Usami, the only members of the Secret Sealing Club, are two of those people. Together, they commit themselves to finding out more about Gensokyo, from the tens of thousands of years ago Genso-Lunar War to the background of the Moriya Shrine. Even the sky cannot contain their rising curiosity, whether it be through casual conversation, in-depth talks, or the pursuit of individuals who could have connections to this mysterious realm.
