Monster Girl Encyclopedia I

Monster Girl Encyclopedia I (魔物娘図鑑 Ⅰ) is the original book of the Monster Girl Encyclopedia series by Kenkou Cross. It includes information on the monster girl world, interspersed with 100 monster girl profiles, to introduce the reader to some of the inhabitants of this lewd and lascivious universe. Like several other works of the series, this first encyclopedia has a frame story where it is also a publication in its own setting, and the reader is addressed as though both they and the author can travel and interact with the various sexy species described.

The frame story of Monster Girl Encyclopedia I involves "A certain wandering scholar of monsters", its author, travelling the land and interviewing different monster girls you might find when exploring this setting; their diets, habitats, and the various inventive ways they're likely to seduce males who stumble into their territories. Small parts of the text are written with the help of the head baphomet of the Sabbath. Wandering Scholar even interviews the Mamono Lord, the monsters' leader, who describes how the once traditional swords-and-sorcery world had its dragons, orcs, and goblin foes replaced by cute, super-lustful monster girls. The wandering scholar's evidence-based approach to monsterology brings him into conflict with the major human organization of the world, the Order of the Chief God. He ends up having to flee for his life, which leads on to the next book, Monster Girl Encyclopedia World Guide I: Fallen Maidens.

The hundred monster girls whose profiles appear in this book are, in order: Succubus, Lesser Succubus, Slime, Red Slime, Queen Slime, Goblin, Hobgoblin, Werewolf, Werecat, Wererabbit, Weresheep, Alraune, Mandragora, Matango, Dryad, Honey Bee, Hornet, Grizzly, Harpy, Black Harpy, Cockatrice, Orc, Ogre, Arachne, Lamia, Medusa, Echidna, Lizardman, Salamander, Werebat, Centaur, Unicorn, Minotaur, Holstaur, Giant Ant, Ant Arachne, Mantis, Fairy, Pixie, Leanan Sidhe, Kesaran Pasaran, Elf, Dark Elf, Dwarf, Amazoness, Alice, Alp, Cyclops, Mermaid, Merrow, Sea Bishop, Nereid, Scylla, Charybdis, Sea Slime, Siren, Sahuagin, Bubble Slime, Large Mouse, Giant Slug, Devil Bug, Roper, Golem, Gargoyle, Mimic, Pot Devil, Mummy, Sphinx, Anubis, Girtablilu, Zombie, Ghoul, Ghost, Skeleton, Nightmare, Doppelganger, Dullahan, Vampire, Imp, Dark Slime, Beelzebub, Baphomet, Witch, Youko, Yuki-Onna, Red Oni, Crow Tengu, Kappa, Jorou-Gumo, Inari, Angel, Dark Angel, Dark Priest, Dragon, Undine, Ignis, Sylph, Gnome, Dark Matter, Lilim
