Iku Iku Succubus

Iku Iku Succubus is a visual novel set in modern Japan, where university professor Tanehisa Busujima is assigned to teach study-abroad students from the Succubus Kingdom. His job is at risk because of his lack of restraint, but the university president gives him a chance to stay on as their instructor. The exchange is part of an agreement between the Japanese government and the Succubus Kingdom: the kingdom will help address Japan’s declining birthrate, while Japan supplies male energy. Though Busujima is supposed to teach the students about the Human Realm, program director Lima tells him that his real task is to rehabilitate two failed succubi in his care.

The Succubus Kingdom

The Succubus Kingdom lies in the Dream Realm, a separate world from the Human Realm. Its students come to a university in Japan through the government’s exchange agreement, bringing magic, demons and witches into the story. The visual novel offers over 10 hours of story, is fully voice acted, and has multiple endings.

The heroines

You choose between three heroines, each with her own background and personality:

• Lima Grimalkin: A short, intelligent feline succubus with powerful magic, a teasing and belittling manner, and ambitions to rise further in the Succubus Kingdom. Despite the Grimalkin clan’s declining status, she became director of the study-abroad program. Some other clans disdain her and believe she reached her position through luck.
• Ruk Orcus: A carefree, kindhearted swine succubus from the highly esteemed Orcus clan. Sheltered and curious about Human Realm food, she often posts pictures of her meals on Incugram. She considers humans inferior to succubi and believes Lima is unfit for her position, though neither view comes from malice. Ruk speaks in a refined way, but can be foolish or silly.
• Ico Bicorn: A rebellious succubus from a horned-beast clan known for its militancy. Raised on the idea that modesty and marriage have no place in a succubus’s life, she wants to remain faithful to the person she eventually chooses. The Succubus Kingdom treats devotion as taboo, and Ico’s hostile manner, golden skin, muscular build and large, spear-like horns make her stand out.
